At the end of Volume 9, Azazel mentions that Ravel is transferring to Kuoh Academy as a first-year student.

Ravel arrived in Volume 10 and became a first-year student alongside Gasper and Koneko (the latter with whom she has a love/hate relationship), and later moves into the Hyoudou Residence with Issei and co. so that she could spend more time with him. Ravel later gets a call from her mother asking Rias and Issei to look after her. After the conclusion of the Rating Game between Rias and Sairaorg, she comes into the clubroom with a big cake unaware that everyone was spying on Issei's confession to Rias.

At the beginning of Volume 11, she becomes Issei's manager in the Underworld under Sirzechs Lucifer's request, due to the latter's show gaining popularity among the children. Later on, in the end, she starts crying after realizing Issei's demise upon seeing his Pawn Evil Pieces.

She aids Issei in choosing a Magician and, while doing so, gave her opinion on Rias Gremory's Peerage and how they were unique among the Devils. She later throws a tantrum about Koneko sitting on Issei's lap, and proceeds to push her off and sit on Issei's lap herself which resulted in the two fightimg over Issei's lap once again. The night after the arrival of Elmenhilde Karnstein, Ravel entered the bath while Issei was in it, and while washing his back, she tells him that she would like to continue being his manager. She is later kidnapped alongside Koneko and Gasper during an attack on Kuoh Academy during school hours. She, along with her fellow first years, are rescued by the combined forces of the Gremory and Sitri groups. After reuniting with Issei, she proclaims that she never lost faith in him and believed that he would rescue them.

In Volume 15, Ravel continues to assist Issei in finding a magician for him to make a pact with, where as Kuroka suggested that Le Fay might be suitable for it. However, Ravel turned it down due to Le Fay's former affiliation with the Khaos Brigade. Regardless, Ravel does question Le Fay and discovered that she has actually surpassed her criteria to assume the role.

In Volume 16, Ravel saw off the Occult Research Club members, Bennia and Loup Garou who are going to Romania to aid Rias and Yuuto. She reminded Issei to mind his appearance, just like a manager would. After the meeting for the formation of D×D ended, Ravel accepted Issei's request to make Le Fay his contracted magician.

Ravel oversaw Issei's contract ceremony with Le Fay in Volume 17 and was successful in making a 5-year pact between the two. She also went with the Occult Research Club to the Underworld to participate in the experience day in the school Sona Sitri built, during which she managed Issei's Oppai Dragon activities as well as sneaking into his bedroom to sleep with him, wearing nothing but an old shirt and panties while using Issei's arm as a hug pillow.

She is later seen along with the other girls observing the Interdimensional Room that Touji Shidou brought for Irina to be able to have sex with Issei without falling and commented on how if Kuroka found out about it she would take Issei inside and not let him go until he had copulated with her.

In the Extra Life of DX.1, While Ravel plays chess with Rias in the club room, they think back to the Rating Game against Riser and wonder what the outcome would've been with Rias' current peerage, with everyone taking an interest in the idea, leading Ravel to call her brother for a rematch. The Rating Game began on their next holiday, however, this time Ravel does not participate in it this time instead asks Irina to take her previous place as Risers Bishop. The end match resulted in the Gremory Teams victory. A few days after the Phoenix match, Ravel and Rias have another discussion and come to Azazel to set a Scramble Flag match with Seekvaira Agares.

In Volume 19, Ravel informs everyone that she will be rejoining her brother's Peerage for his Rating Game match with Diehauser Belial. Later while everyone was enjoying the underground pool within the Hyoudou Residence, she sorts out a timetable for Issei to apply sunscreen onto anyone who requested it. She is later seen seeing everyone off as they go into battle against the rebelling Exorcists. During Riser's Rating game, she joined alongside her brother as the only peerage left standing entering a dome-shaped cavern where they meet up with Diehauser. While Riser was excited to fight against him, he became confused towards Diehauser's sentences, Ravel senses something and is shot in the abdomen while protecting her brother from their opponents demonic spear, leaving her fatally injured unable to regenerate due to Diehausers "Worthless" ability and the games system could remove her from the field. The winner of the match is left ambiguously as Ravel, Riser, and Diehauser went missing.

A few days later, Ravel and Riser were recovered in Volume 20, under Ajuka's care, who DxD members met in a different dimension and took in the unconscious Ravel while her brother was already escorted to the Phenex Mansion by the Slash Dog Team. Back at the Hyoudou Residence, after Issei's parents were kidnapped, Ravel came to him with regrets for not being by his side during all the critical moments, however, he assures her that she has always given him confidence when he fights an enemy. They vowed to always stay together and that he will come back alive with everyone.

In Volume 21, when Issei was discharged from the hospital and met up with his friends, concerned for his safety, Ravel gave him a small bottle of Phoenix Tears she made herself before they head off into battle. They later appeared on an island in the coastal waters of Japan where she and the rest battled Apophis and his army of Evil Dragons and fake Scale Mails.

In Volume 22, Ravel barged into Issei's room to give him the news that the Rating Game World Tournament have been officially announced, only to interrupt Rias and Akeno from attempting to take his virginity. He, Ravel and Koneko were present in the club room when Nakiri Ouryuu whom the trio were already acquainted with, introduced himself to the others. On the following weekend, the ORC group, Issei's parents and the Vali Team attended a fishing trip on an inhabited island owned by someone related to them.

Ravel primarily served as the teams strategist, but after ten days, their group mainly received bad reviews in the tournament after their first few matches. For their next match up, Issei's team would eventually went up against Baraqiels team of Fallen Angels under the Rating Game rules Object.

The victor goes to her team when Issei defeated Baraqiel while proposing to Akeno.

In Volume 23, by this time, Ravel had already enrolled in her school a year up along with her peers. She and her team had just won another match for their ongoing winning streak. While in the waiting room, when Xenovia worried how easily their ongoing victories could be halted, Ravel added that at this point it was natural for most teams and they must come op with countermeasures even if she admitted to being an amateur. Elmenhilde then hands Ravel a clipboard, to which upon checking ended their meeting for Issei to continue his work as a High-Class Devil.

Later on after school, they continued their Devil work underneath a cram school building where it lies a lab that Azazel had set up which has now became the workplace for Issei and his peerage as they now work for a branch store in the Gremory Large Enterprise, Ravel handled receiving the payment of object everyone comes back with from their jobs and check their worth with a professional. Though when Asia came back she passed Ravel, forgetting to hand her payment. She and Issei had a private discussion concering Asia while observing her customers questionnaire and believed that Asia was over exerting herself as the new President of the ORC. Ravel smiled at Issei who expressed worry for his peerage and agreed to help her when they can, the two came out of the storeroom with everyone accusing them of workplace romance, Issei attempted to deny it while it occurred it Ravel that storeroom could also be used as such. Elmenhilde came in with tea to serve for everyone to be as helpful as she could but soon enough tripped and nearly broke the teacup if it weren't for Xenovia, Ravel had also given her a strict training menu with Xenovia that she must follow if she were to join them in the Tournament

During the meeting, Duilio was getting Issei detracted with Sister Mirana's chest, asking his manager for help, Ravel suggested that she'll let him touch hers if he resisted the Sisters. She was surprised to witnessed that Rudiger had become the opponents supervisor and could see through Asia's troubles, revealing that he had also been gathering as much Intel from them as he could, with that she interrupted Irina from reveal Elmenhilde was also present as to not give too much away. That evening, Ravel came to join Issei in bed in place of Rias and Akeno who were absent which she excused it as simply her duties as his manager. Ravel grabbed his hand to place it on her breast, she called back to when everyone misinterpret the office storeroom incident when she replayed to them that she would answer all of Issei impulsive requests, going on to say to Issei that her body and mind now belong to him; her King. Their moment was interrupted when Asia also came to spend the night, Ravel attempted to explain her situation a was merely her duty when Xenovia and Irina had rushed towards Issei like ninjas. Everyone clinged to Issei showing off their breasts to him and how they tried different methods in making them big, Ravel also explained that Devil's bust continues to grow even after maturing due to their Demonic energy.

Days later after school within the clubroom, Issei had previously asked Ravel to find anyone suitable to join their team, to which she narrowed down to Ouryuu Nakari to meet with them, though following him was Tiamat as the boy was in her care and only allowed him to join on the condition that if they won they'd have to use the prized wish to return all of her treasure. Ravel explained to Issei the number of wishes the winners gets depand on how grand they were. Elmenhilde who had requested to join beforehand and gone through training questioned her standing, Ravel told her that she was still under consideration that she still doesn't know what her true intentions are, though the Vampire girl kept insisting that it was for sake of the Carmilla faction and the motherland.

At that point they were greeted by the surprised visit from Roygun Belphegor by Ravel's aforementioned brother for a a job. She handed documents game data that could be useful in their next fight, while she may have found them to be helpful, she pulled Issei back from Roygun who attempted to flirt with, recalling the rumors about her liking younger males. Roygun soon left with heartfelt smile when the girls present gave off stinging gazes towards Issei while Ravel continue to hold onto his arm.

In Volume 24, everyone came to the school pool for an enjoyable time, which is when all of Issei's fiances fought over who should he apply suntan oil to first, therefore she organised a line in which order he will do so to all of them. Shortly after, she scolds Kuroka for attempting to cut in line before she ran off. Everyone then immediately headed to the Hyoudou Rsidence once they heard that all of their parents and guardians have gathered there. Upon arrival, they learned the reason for their meeting was to discuss plans for wedding ceremonies for each of Issei's fiances. Her mother states that the Phoenix House shall oversee the series of schedules, she also teased that her daughter eventually get engaged and makes arraignments for her anyway.

The next day while she was out shopping with Issei, Bennia and Ouryuu came rushing to them warning that a group of Grim Reapers were attacking their school, specifically Koneko and other Gasper and Millarca. They were able to arrive just in time to save all of them. they soon learned that the reason for their assault was to target Kuroka and Koneko were being targeted by Grim Reapers due to being involved in their late father's research in artificially creating Super Devils. When it came time for Rias and Vali's Rating Game match, Ravel along with her friends and members of Tobio's Slash Dog team fended off the Grim Reapers from interfering with the match. Lavinia took the lead in having frozen all of them in place, allowing the rest to easily strike them. When all their enemies were dealt with, Issei used his new ability to contact Koneko and Kuroka via her breasts to assure them they are now safe and proposes to them both at the spot.

Everyone then payed Rias a visit at the medical room, there she was thanked by Koneko for also trying to protect her and asked to refer to her as "Shirone". She then watched as almost all of Issei's fiances requested kisses from Issei as Koneko and Kuroka were hogging him for themselves.

In Volume 25, Ravel 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.

On the day of the match, Ravel travels together with her team to Valhalla in Norse mythology at the Thor Stadium for their fight against Team Leisure of the Kings. Ravel tells the team about the promotion of Pawn is possible after reaching the halfway point after listening to the rules of the match and it’s unnatural if they lose the match because of the difference there is between our basic fighting power and theirs and bravely says to her team to win because they’re many opportunities for us to win because of the rules. Ravel asked Roygun about her specialty of Crack abilities because she can tear on anything but Roygun tells Ravel that she has limits as there are those who are more powerful than her such as Satan-class and God-class and Ravel looked at the artificial Yggdrasil as she wanted Roygun to use her Crack on the Yggdrasil’s roots and make the tree fall over. When the match started, Ravel joined Issei, Irina, Rossweisse, Xenovia, and Ouryuu in the stairways of the artificial Yggdrasil. As Issei fights against Vidar, Ravel fights together with Rossweisse against Brynhildr and the Valkyrie Squad and tells her teammate she would try much to assist her. During the battle, Ravel took damage from Valkyries’ fire magic but she used her family’s regeneration abilities to heal her injuries at the cost of her stamina. As the Valkyrie Squad released their attacking stance because of Rossweisse revealing to them that she kissed Issei, Ravel and Rossweisse counterattack them with magic and defeating four of the Valkyrie Squad. Ravel and her team win the match due to Ddraig defeating Typhon in the fight.

Ravel and the group arrived at the park where Issei was attacked by the unknown devils and transported them to the Underworld, they began to discuss and she and Rias became shocked when Vasco mentioned the devil’s mother Lilith being involved. After the discussion, Ravel rushes to Issei’s room after hearing the girls fighting over the rights to sleep with Issei and wanting to sleep with him as well, in the end all the girls ended up sleeping with him. Ravel and the group arrived at the town where the devils were residing, while the group were fighting against them, she protected Asia from any attacks coming from the devils. Ravel and the others became shocked to see Issei, Ddraig, and Bova in pain when the purple-haired started singing until Rossweisse stopped her with Hypnosis spell.

Ravel and the others were astonished to learn from Ajuka that the girl is Ingvild Leviathan, a descendant of Leviathan and a half-human Longinus wielder. After the meeting with Ajuka, Ravel went to inform Issei that Ingvild has woken up from her sleep and decided to take her to the beach so she can see the sea. They went to beach in a unpopulated island with a barrier, when Akeno prepared their meals, Ravel asked Issei to bring Ingvild to join them until they were interrupted by the arrival of the goddess Nyx. After reporting to Ajuka about Nyx’s actions and gaining the approval from Apollon, Ravel watches as Xenovia and Akeno attempted to have sex with Issei to help him lose his virginity so he fight Nyx, but she reminded them that Rias is the first and they need to earn her permission, despite wanting to do it herself. Ravel and the others headed to Nyx’s location until they were intercepted by the devils and uses her Phenex fire on them and later reminded Issei that Rias is waiting ahead. While Issei was fighting Nyx, Ravel was fighting the devils that was summoned by the goddess.

After Nyx was defeated, Ravel and her team headed to the Agares territory for the tournament announcing the next matches and they will be facing Rias and her team in the first match.

In True Volume 2, Ravel appeared in Issei’s dream of him being in his wedding ceremony to marry his brides and she informed Issei that his second group of brides are ready to be wed so they need to be finished. In the morning, Ravel went to do a morning marathon with Issei, Ingvild, Ouryuu, and Bova in order to boost their stamina and they were joined by Elmenhilde. Ravel became concerned of Elmenhilde’s condition as she was becoming more exhausted, so she told her to rest, but Elmenhilde wishes to continue for another five minutes until Asia arrived at the park to give them some tea and ended their training. When Ingvild about to do her devil job, Ravel noticed her demonic power is too vast for her control and might cause an explosion once she reaches her destination, so Issei decided to go with her on his magic circle.
