Xenovia Quarta is one of the many female protagonists of High School DxD. She is a third-year high school student at Kuoh Academy in Class 3-B and is a natural-born Holy Sword user who wields the Durandal. After learning the truth of God's death in the war, she was excommunicated from the Church and decided to join the Occult Research Club as Rias' second Knight, alongside Yuuto. After Issei's promotion, she now serves under him as his first Knight and is also one of his fiancées.


Xenovia is a young woman with chin-length blue hair with a dyed green fringe on the right side and brown eyes (dark yellow in the anime, season 2-3). Her body measurements are [B87-W58-H88 cm] [B34-W23-H35 in], and her body weight is [56 kg] [123 lbs]. Xenovia's height 166 cm (5 feet 5 inches).

Her battle attire is her Church battle suit, which consists of a black, skin-tight, short sleeve leotard with pauldrons, matching fingerless gloves that extend to her biceps, and thigh-high boots, all of which are adorned with straps. This attire is worn under a white hooded cloak with gold and blue accents. She also wears a crucifix around her neck, which was later removed after becoming a Devil.

After joining Issei's peerage and during the Rating Games, Xenovia wears a uniform that consists of a red button top with a white tie and red shorts. She also wears a black waist cape as well as a purple cape over her left shoulder.

Upon transferring to Kuoh Academy and joining the Occult Research Club, she wears the Kuoh Academy girls' uniform but without the cape.


When Xenovia was first introduced, she was shown to have a calm, quiet, and serious demeanor, putting her mission first and only speaking when necessary. She was also very cold, bordering on heartless, as she called Asia a witch for becoming a Devil (even though she became one unwillingly so she could be with Issei) and even went so far as to try and kill her. She later threatened to do the same to Kiba when he was technically a Stray. After being reborn as a Devil, however, she gains a very close relationship with Asia, being touched by her kindness and apologizes for calling her a witch when they first met.

While a faithful member of the Church, her beliefs are flexible enough to accept help from a Dragon such as receiving a free lunch (after Irina spent all their money on a fake painting of a Saint) and wanting to not only accomplish their mission but survive afterward as well.

In battle, Xenovia appears to be a bit arrogant, stubborn, and rarely using her head and attempting to overwhelm her opponents with pure power and strength instead of being subtle or using skills. According to Issei, her fighting style is comparable to that of a Rook despite being a Knight, referring to her as a "Power idiot". As Xenovia was raised in the Church, she lacks common knowledge on the life of a normal person, evident when she brought a box of condoms to school as well as wanting to give birth to strong children, and has chosen Issei as her mate. As the series progresses, it is shown that Xenovia has developed genuine romantic feelings towards Issei due to him protecting his comrades even if he gets injured by doing so. As a result, she becomes more aggressive in seducing him, which proves that Xenovia is quite perverted as well, a fact that she is "cool" with.

While still a faithful Christian, Xenovia has become extremely flexible and open-minded with her beliefs as shown when she deeply sympathized with Masaomi's tragedy and during their Second fight, she shed tears for Masaomi's agony contrary to her calm and serious nature in battle.


Since her childhood, she has endeavored in her training and studies for God and her religion. She was also raised and trained as the wielder of Durandal under Griselda Quarta as her sword master and legal guardian. Eventually, she becomes an exorcist, an agent of the Catholic Church, and partnered with Irina Shidou.

After Xenovia's life was put in danger three years prior to the series, because of her formerly long hair in a mission with Irina to exterminate a stray vampire from the House of Manthar, she chose to cut her long hair to prevent that kind of thing from happening again. She also dyed a part of her hair green for fashion.


Birth of the Breast Dragon EmperorEdit

Xenovia first appears in Volume 3 along with Irina under the order of the Church to retrieve the three stolen Excalibur swords. She and Irina formed a temporary alliance with Issei, Yuuto, Koneko, and Saji, in which they would retrieve the stolen Excaliburs fragments but would allow Yuuto to destroy one of them. During the fight with Freed Sellzen and Valper Galilei, she reveals herself to be the wielder of Durandal and quickly turns the tide of battle by destroying the fused Excalibur and cutting down Freed. Following the battle with the Fallen Angel leader Kokabiel, she became a Devil under Rias after finding out that God died.

Before the time was up, they reconfirmed their plan and Xenovia ended up pairing with Tsubasa of the Sitri group and fought with the mass-produced Evil Dragons. After the fights were settled, she revealed her plan to run for the next Student Council President to Issei and the others.

Later the club members are challenged to participate in the fight against the exorcists that rebelled against the Church. Xenovia was troubled as she needs to fight against the former wielder of Durandal, Vasco Strada, that is said to be the closest to the original wielder Roland. While Issei was meditating in the underground pool, Xenovia entered planning to do her usual routine of skinny-dipping. During their talk, Xenovia expressed her worries of being unable to surpass Sona as the Student Council President and Vasco as the wielder of Durandal. Issei told her that she can do it and asked her why she chose to run as the Student Council President. Xenovia reasoned that she loves Kuoh Academy as it has given a lot to her and she just wants to give something back. Xenovia pulled Issei into the pool with her and kissed him a second time and reminded him of her intent to join his peerage once he becomes a High-class Devil.

During the fight against Vasco, even with the combined abilities of Excalibur, he was able to fight evenly against Xenovia saying that it is alright to combine the abilities of Excalibur but she must not forget the essence of Durandal which is pure power. This prompted Xenovia to dual wield Durandal and the True Excalibur. She and Vasco then clashed resulting in Strada's defeat. After Strada's defeat, Walburga appeared and fought against them using her Balance Breaker. Xenovia was able to defeat her Balance Breaker by sending a huge amount of holy aura from Durandal and True Excalibur in a criss-cross fashion while Issei defeated Walburga.

After the fights were settled, Xenovia was seen giving a speech in front of the students as part of her campaign and it was well received by the students. After the speech, Xenovia asked permission from Griselda to use Irina's room to make babies with Issei which resulted in Griselda scolding her and made Xenovia use her surname once again to remind her that Griselda is her sister. At a later date, it was announced that Xenovia won the election and became the new Student Council President.

In Volume 20, along with everyone in her year, Xenovia attends to her school's career consultations with Griselda meeting her teacher. A few days later, Xenovia and members of D×D meet up with Ajuka who has recovered Ravel and explains the shocking revelation about the secret King Pieces.

Xenovia assisted Issei and Asia to help find their parents by clearing a path through an army of Evil Dragons along with Kiba and Irina.

In Volume 21, days after Trihexa had been unleashed and wrought havoc onto the world, Xenovia and all her friends joined the army on an island on the coastal waters of Japan where they battled Qlippoth's army of Evil Dragons, fake Scale Mails and one of the imperial beast bodies controlled by Apophis.

In Volume 22, Xenovia arrived together with Asia and Irina and witness Rias and Akeno seducing Issei with Xenovia expressing jealousy of wanting her own Interdimensional room. During school, Xenovia and everyone had finished their end of semester test. At the club room preparing for the new year while reminiscing over the past, Xenovia reveals she wants to take a job of teaching and start a cram school. Xenovia praised Issei's achievement and his promotion to a High-Class Devil within one year. One of Xenovia's secretaries of the Student Council, Ouryuu Nakiri came to deliver the documents and reminded her that she was going to introduce him to everyone. Xenovia tells Issei that if anything happens they should call Ouryuu to assist them.

Next weekend, the Occult Research Club, Vali's team and Issei's parents went on a fishing trip on an inhabited island owned by someone related to them.

Red Dragon Emperor of the Blazing Truth × White Dragon Emperor of the Morning Star: The True Dragon(s) of the Kuoh AcademyEdit

Xenovia arrives together with Issei and their fellow team members at the Azazel Cup through Ryuuteimaru. After ten days, Xenovia gave a bitter expression of their bad ratings and also agreed to Issei's decision. During the rating game tournament against Baraqiel, Xenovia successfully defeated Baraqiel's knight and two pawns. Xenovia and Irina take on a man with thunderclouds supporting him. Xenovia then gave her praise to Issei for his confession to Akeno. After the match, Xenovia watches as Rias and Akeno bicker over Issei while also saying to Asia and Irina that they need to get closer to Issei and make him take responsibility for them.

In Volume 23, Xenovia and the rest of her classmates have now enrolled in as third years. After winning another recent match for their continuing victories, in the waiting room Xenovia was the only one feeling gloomy as she worried that bad things could happen in times like these, they discussed the possibility of countermeasures to ensure everything goes smoothly. Xenovia and her team were then announced that they will be battling Dulio's team of reincarnated Angels. At school, a Ball Tournament was announced with participating as a member of the Student Council team, pitting her against Asia, Irina and the ORC members, though the trio had a simple friendly declaration of war. Later on underneath a cram school building lies a lab that Azazel had set up which now became the workplace of Issei's peerage as they now work for a branch store in the Gremory Large Enterprise, the requests concerning any physical activity were left to Xenovia, she soon entered the room still unused to the elevator followed by a long corridor with multiple doors.

Xenovia notice Asia was a little unwell after Issei came back from talking with Asia within the storeroom, Xenovia and the other girls mistook it as shameless acts within the workplace. When Elmenhilde brought tea for everyone, she tripped which lead Xenovia to take out Excalibur and halted the teacups and tray in mid-air. When Elmenhilde poured the tea, Xenovia complained how was bad she was at it, then commented that she herself who only knows how to fight and eat had no right to say. Both Issei's and Dulio's teams met up with each other at the Hyoudou Residence as to get its members acquainted with each other, Xenovia reluctantly met up with a familiar face; Nero Raimondi who was as energetic and childish as she remembers. When Dulio was notifying Issei that Mirana had enormous breasts, Xenovia suspected that it was part of the Joker's strategy to distract Issei during the match, which he revealed to have been intended. Xenovia then wore a complex expression on her face when Griselda thanked her friends for looking after her. Later that night, when Issei was in bed with Ravel and Asia, Xenovia and Irina switched off the lights and then came running in like ninjas to also cling to him for staring too much at Mirana's breasts. The five of them then spend the night together, where she kicked Issei off the bed again due to his bad sleeping habits.

Needing to strengthen their fighting numbers, Ravel called Ouryuu to meet with them, Xenovia vouched for him as someone she has sparred with. She and Irina ran into Issei with Lint Sellzen in the living room, the two immediately take a liking to her as her seniors of the Church and came to be more acquainted with her. The next day, she had a mock battle with Irina as their next game approaches. The time came for both teams to have their match at the Ajuka Stadium in the Astaroth territory with the game they'll be playing called Rampage Ball. As the game commenced, the whole team headed after the ball before the other team could, they were met with thunderclouds created by Dulio that caused icy cold heavy rain accompanied by lightning strikes that they had to dodge. Xenovia was the first to attain the ball. She then fought against Nero who rushed in to retrieve the ball from her, passed the ball to Bova under Issei's orders. While Nero was able to get the ball from Bova, Ouryuu managed to gain it back and score his team the first 5 points. At one point as part of Rudiger's plan, Xenovia had to back up Irina, which allowed for Dulio's team to score. As she was about to fight with Nero next, that's when Ravel gave Issei the signal to use his Wyverns to create Xenovia's own variation of the Scale Mail armor; Crimson Destruction Dragonar, with she was able to regain strength, Nero then responded by releasing his Balance Breaker and the two began a fierce melee battle.

The game continued for about a solid 2 hours. As Dulio with the ball headed top for the next goal, Irina and Xenovia closed in on him but were intervened by the opponent's swordsman; Kiyotora Shinra who wielded two ethereal katanas, Rossweisse tried to assist them but failed when Mirana and Griselda blocked her attack and forced the Valkyrie to retreat. With everyone's stamina nearly empty, Xenovia came to Issei claiming to have a trump card but may collapse though depending on his answer. Xenovia then proposed to him out loud to take her as his bride, not only was he and everyone present shocked by this, but Irina requested that he also take her as his bride too. Issei soon regains his composure and accepted them both and as if the fatigue of the two was blown away, they both gained a huge motivation as well as a massive power boost as unbelievable aura surged forth from their Holy Swords.

The two were able to send the opponents in their way flying off, then Xenovia took out her Excalibur and were able to use Ruler to snatch the ball from her opponent from a far distance to Elmenhilde. Full of confidence, Xenovia took out Excalibur and claimed she felt like she could even take down a Satan while proclaiming to Issei that she wanted at least five children (three boys and two girls) further embarrassing Issei, she continued to express her dreams for her future children as she then faced Griselda who was not amused that she had gotten engaged without informing her first, while she simply tells to rejoice at the beginning of her journey. Griselda still intended to give a lecture afterward. With all the focus now on Issei, Xenovia, Irina and Elmenhilde, none of the opposing members notice Asia who was able to score a goal.

The ball was soon passed to Xenovia when Nero stood in her way again, she threw the ball in the air to bring out Excalibur again to be used alongside her Durandal for her signature technique; Cross x Crisis that has been augmented by the dragon armor she wore, completely obliterating the surrounding terrain. Nero, who was engulfed in the holy aura, was able to stand up and charge at the fallen Xenovia but had reached his limit also, before passing the ball to his comrades. As the timer goes off, the end resulted in Dulio's team to come out victorious with the score being 144 – 146. Xenovia and Nero, who has regained consciousness, began arguing. But then the two of them smiled as they shook hands. Later when the Ball Tournament had already commenced, it was Xenovia's Student Council pitted against Asia's Occult Research Club in a game of basketball, which soon ended in a draw. On their way home, Xenovia and Irina just happened to come by Issei proposing to Asia and hid not wanting to ruin the moment. Xenovia contemplates how her engagement could've been just as romantic but shed tears as they're all happy that the three of them are now engaged and hugged each other in joy.

Xenovia appeared in Volume DX.4, participating in her team’s strategy meeting for their upcoming match against Sona and her team and revealed that some of Sona’s peerage members like Ruruko, Tsubasa, Tomoe, and Momo’s artificial Sacred Gears have reached balance breakers. Xenovia makes a request to Ravel to allow her face Sona alone in order prove her worth of being the student council president. Xenovia had Issei accompany her to Saji’s house to deliver some documents he had forgotten and they meet Saji’s siblings Kaho and Gengo. On the day of the match, Xenovia and her team headed to the Armaros Colosseum in the fallen angel’s territory and challenged Sona to battle. She destroyed Sona’s water dragons with her enhanced Durandal holy wave and uses both her Durandal and Excalibur to perform her Cross x Crisis technique to the number of water beasts and defeat Sona, which ended in her team’s victory.

In Volume 24, Xenovia and everyone was enjoying their time at the pool when they heard that all of their parents and guardians are meeting at the Hyoudou Residence. As Xenovia and the rest arrived, they learned that they've gathered together to discuss plans for their wedding ceremonies, all the girls engaged to Issei made their personal requests with Xenovia discussing with Griselda.

She and her comrades would later have to protect Koneko and Kuroka from Grim Reapers led by Thanatos. During the Rating Match between Rias and Vali, Xenovia and her comrades along with members of Tobio's Slash Dog team fended Grim Reapers from interfering, with Lavinia having frozen all of them in place. When all their enemies were dealt with, Xenovia and the rest went to watch the ending of the match, witnessing Rias having to reluctantly forfeit. She and everyone else later paid Rias a visit at the medical room. Xenovia and almost every girl present requested kisses from Issei as Koneko and Kuroka were hugging him.

A few days later, she and her team were gathered at the Hyoudou Residence VIP room by Shemhazai to give them all certain items Azazel had handed to him, Xenovia was given Excalibur's scabbard. They then met with the others who informed them of Mahabali's loss in the tournament and the opposing sides members; Verrine and Balberith whom they feel a tense pressure from as they claimed to be Super Devils. They began gathering information concerning the new enemies they've met earlier. Just then, Xenovia and everyone heard about Rossweisse's message that she'll partake in an arranged marriage with Vidar, news that everyone let out a surprised shock over after a slow pause.

In Volume 25, Xenovia and her team were watching the tournament in Issei’s room and sees Diehauser winning against God-class beings which amazes her because he only participated in the middle of the tournament. They also watch about mysterious new devils Balberith and Verrine, and the Shooting Star team who owns new Sacred Gears. After Rossweisse’s marriage with the Chief-God Vidar, Asia, and the team began to analyze the members of Team Leisure of the Kings such as Typhon and his weather abilities, Apollon whose light power is dangerous even to ultimate-class devils, and Vidar’s kicks and mystical boots put him on par with Thor. Rias comes to Issei’s room and informed the team that they been summoned to the VIP by Ajuka who offered to help train both teams in the smartphone game called Beelzebut. During their break from training and the girls start thinking about Issei, Xenovia and Irina became confused by their talk and wondered if they should become a kidnapped princess so Issei can come and save them but it’s impossible due to them being born in the battlefield. After training at the Beelzebut, Xenovia slept together with Asia and Irina in order to deepen their friendship.

On the day of the match, Xenovia travels together with her team to Valhalla in Norse mythology at the Thor Stadium for their fight against Team Leisure of the Kings. When the match started Xenovia joined Issei, Irina, Rossweisse, Ravel, and Ouryuu in the stairways of the artificial Yggdrasil. In one of the floating islands, Xenovia joined together with Irina and Ouryuu and became the first opponents to the current chief-god of Olympus Apollon with Xenovia introducing herself as Issei’s knight. Xenovia in her Crimson Destruction Dragon armor and Irina attempt to attack Apollon but he stopped their attacks with his divine aura and continued to dodge their attacks. Xenovia uses her Excalibur Mimic to lash at Apollon while making it invisible with Excalibur Transparency but he still managed to dodge her attacks despite being unable to see it. Xenovia changed using her Excalibur Ruler to charge Touki bullets direction and cornered Apollon but he still managed to dodge them and punch Xenovia with his power of light, which also destroyed her armor. Xenovia didn’t retire because of her Scabbard of Excalibur giving her immortality with Apollon praising her for using that weapon and Xenovia was joined by Irina and Ouryuu who declare their wills to fight for Issei which impressed Apollon who decided to fight them seriously. Xenovia was defeated along with Irina and Ouryuu but didn’t retire due to her Scabbard and was trapped in the cage of light by Apollon in order to keep her from joining the fight. Having broken through the cage of light, Xenovia fired her Cross Crisis at Apollon and wishes to continue fighting him until her strength is depleted. Xenovia and her team won the match due to Ddraig defeating Typhon and retiring him.

Xenovia and her teammates celebrated at the Hyoudou Residence along with the rival teams for passing the preliminaries and entering the main stage of the tournament. As Issei was surrounded by his rivals, Xenovia, Asia, and Irina pulled Issei away from them with Xenovia fearing that he will be taken by men.

Xenovia reappeared in True Volume 1, informing Issei he has a call from Morisawa. After Rias announced her engagement to Issei to the people of the Underworld, Xenovia and Asia became frightened of doing a press conference of their own with Issei until Rias assured them that they don’t have to do the conference. Xenovia was one of the girls summoned by Morisawa to jokingly ask her to go out with him, but she revealed that she has Issei as her boyfriend and already has a promise future with him and after Issei returns from his devil job, she joined the other girls to wash Issei’s body. Xenovia and the group began to discuss about the devils that attacked Issei at the park and she came to suggest to know the mastermind and they should attack them first and listened to the opinions of Vasco. After the discussion, Xenovia and Irina started to bicker over the rights of sleeping beside Issei until all the girls ended up sleeping with him. Xenovia and the group arrived at the town where the devils were residing and she defeated several of them using her Durandal. Xenovia and the group became shocked seeing Issei, Ddraig, and Bova in pain after a purple-haired girl started singing, Xenovia and Yuuto attempt to face her until Issei told them not to attack her because of their meeting. Xenovia and the group were astonished to learn that the girl is Ingvild Leviathan, a descendant of the original Leviathan and a half-human Longinus wielder.

After Ingvild woke up from her sleep, Xenovia and the group took her to the beach on a unpopulated island with Rossweisse placing a barrier. Xenovia and Irina went to swim and play in the sea. As Akeno took out her handmade bento, Xenovia and Irina got out of the sea to eat the sandwiches until the group was interrupted by the arrival of the goddess Nyx. After Issei’s techniques fail to work on Nyx because of her Godly Virgin Killer Clothes, Xenovia and Irina stood up to Nyx because the clothes will have no effect on women and she started teasing Irina if she wanted to be embraced by Issei. After informing Ajuka about Nyx’s actions and gaining the approval from Apollon about defeating her, Xenovia attempt to have sex with Issei to help him lose his virginity so he can fight Nyx, much to the protest of the other girls. Heading to Nyx’s location, Xenovia and the group came across the devils and uses her Durandal Cannon to annihilate several of them. Xenovia and the sword group remained behind to fight off the remaining devils and defeated some of them while using both Durandal and Excalibur with Irina backing her until they assisted by Vasco and Cao Cao.

After Nyx was defeated, Xenovia and her team traveled to the Agares territory for the tournament announcing the next matches and learned she and her team will be facing Rias and her team in the first match and challenge Yuuto as knights.

In True Volume 2, Xenovia appeared in Issei’s dream of him being in the wedding ceremony, with Xenovia among the first and expressing her happiness for becoming a bride. In the morning, Xenovia went to do some training on her own in the large training space. After Ingvild returns from her first devil job with Issei, Xenovia welcomed them back.

Powers & AbilitiesEdit

Demonic Power: Xenovia has all the powers and abilities common to Devils, including the power to cast spells.

Natural-born Holy Sword Wielder: Xenovia is a natural born Holy Sword wielder and is able to wield any Holy Sword without artificial means like Irina. Even reincarnated as a Devil, Xenovia is still able to wield any Holy Sword without any issues.

Master Swordswoman: Xenovia is highly skilled with swords and prefers to dual wield. With the Excalibur Destruction, she could fight equivalently with Yuuto during their first match and also Freed Sellzen. Xenovia, however, is very weak in techniques and prefers to use power in all her attacks. However, she gradually improved her skills as the series progressed and Yuuto stated that if she mastered the use of the True Excalibur within Durandal, she would surpass him. It is stated by Azazel that her power is equal to that of a High-Class devil. In Volume 19, after fighting Strada, she started to return to her dual wielding style and focus back on the power aspect of her fighting. In Volume 25, by using Scabbard of Excalibur, Xenovia was able to keep up with Apollon, God of Sun.

Immense Strength: Due to her years of training in the church, Xenovia is shown to have gained superb arm strength, being able to wield very heavy swords like the Excalibur Destruction and Durandal with ease.

Enhanced Speed: Xenovia is able to move at superhuman speeds. She combines her speed with Durandal's destructive powers, making her a formidable fighter. However, Xenovia is considerably slower than Yuuto due to Xenovia being power-oriented as opposed to the technique-oriented Yuuto. When further combined with the Excalibur Rapidly, her speed is enhanced and she can move as fast as Masaomi.

Immense Stamina: Xenovia has massive amounts of stamina and endurance. She was durable enough to confront Nero at the end of their match. She can still muster enough strength to use Cross Crisis enhanced by Crimson Destruction Dragonar.

Magic: Xenovia can use magic to store away Durandal in another dimension and summon it back when she needs it.

Praying: Xenovia is one of the two Devils, the other being Asia, that can pray to God without receiving damage in the form of a headache after Issei made a request to Michael to allow her to pray to God.

Flight: As a Devil, Xenovia can fly using her wings.


Xenovia and durandal

Xenovia wielding Durandal

Ex-Durandal (エクスデュランダル, Ekusu-Dyurandaru): This is an upgraded version of Durandal, which has been merged with all six Excalibur fragments held by the Church before Xenovia gains the last one in Volume 11, thus granting it the powers of Durandal and Excalibur with Kiba stating she would be able to combat even Cao Cao in balance breaker if she were to master it. Xenovia, however, partially mastered Ruler, Blessing, and Nightmare. In Volume 19, in the battle against Vasco Strada, she accepted the true nature of Durandal and Excalibur, thus letting Xenovia dual wield both the Durandal and True Excalibur.

  • Durandal Cannon (デュランダル・キャノン, Dyurandaru Kyanon ): This is a technique that has been dubbed as such by Issei, in which, Xenovia charges the holy aura of Ex-Durandal, then unleashes the aura as one powerful attack, which can devour her opponents. However, a drawback is that after a single use, it has to be charged up again, but it's not as fast after the first time.
  • Durandal (デュランダル, Dyurandaru): Xenovia's primary weapon. A uniquely-shaped broadsword with a blue blade and a golden edge. Durandal is a unique sword at the point that it responds to the user. For a user that seeks destruction like Xenovia, the Durandal releases a massive amount of aura with destructive powers. Xenovia can also tap into the Durandal's holy aura with other swords, evident when she uses it together with Issei's Ascalon.
    • Durandal Birth: A combination technique between Xenovia and Yuuto, both attack simultaneously with Xenovia unleashing the power of Durandal and Yuuto springing multiple Holy Demonic blades from the ground directing at their target.
  • Excalibur (エクスカリバー, Ekusukaribā): In Volume 9, it is shown that Xenovia can materialize fragments of the Excalibur and dual wield it with Ex-Durandal. In Volume 19, she could materialize the True Excalibur.
    • The Scabbard of Excalibur: This emits holy aura and grants Xenovia limited invulnerability.
  • Cross Crisis (クロス・クライシス Kurosu Kuraishisu): This is a new technique that Xenovia named in their fight against Walburga, in which, she uses Durandal and True Excalibur to augment each other's holy aura before unleashing a powerful cross-shaped attack powerful enough to split apart the purple flamed Yamata no Orochi whose soul had been used for Walburga's Incinerate Antiphon Calvario.

Crimson Destruction Dragonar (クリムゾン・エクスティンクト・ドラグナー, Kurimuzon Desutorakushon Doragunā): Xenovia's own variation of the Scale Mail armor, which she gained by syncing her aura with Issei's that uses his Red Wyverns to attach themselves onto her body which shifts into the form of armor. While wearing the armor, her strength and speed are greatly enhanced. A single swing of Durandal was powerful enough to create a large crater. It is currently unknown if it has all ability to use the functions of Boost, Transfer, and Penetrate like the Crimson Extinct Dragonar, being noted to be similar to Rias' and yet different.

Ascalon (アスカロン, Asukaron): Issei's weapon, Xenovia borrows the sword occasionally in order to tap the Durandal's aura into the Ascalon. After gaining the Ex-Durandal, Xenovia no longer borrows the sword from Issei.

Excalibur Destruction (破壊の聖剣エクスカリバー・デストラクション, Eksukaribā Desutorakushon): Xenovia's initial weapon. A Holy Sword that has the ability to unleash pure, destructive power that can easily shatter anything it comes into contact with. Xenovia abandons the sword after she became a Devil under Rias. However, the sword was later returned to her and fused with Durandal.
