|“||I am a servant of the Red Dragon Emperor, Hyoudou Issei, and someone who will be his wife. —I will keep fighting until the end.||”|
Asia Argento 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 girl with a very gentle heart who possesses a rare Sacred Gear, Twilight Healing, in her body that is capable of healing the wounds of Humans, Angels, Fallen Angels, and Devils alike. She was formerly one of Rias Gremory's Bishops but now serves as Issei Hyoudou's first Bishop and one of his fiancées.
Asia is a pretty young girl with long blonde hair and green eyes. Her body measurements are [B83→85-W55-H81→83 cm]; height is [155 cm] [5 feet 1 inch] and body weight is [44→45 kg] [97→98 lbs]. Her hair flows all the way down to her back, with split bangs over her forehead and a single strand sticking out from the top and sloping backward.
Her former main attire consisted of a dark teal nun outfit with light blue accents, a white veil over her head with light blue accents, a brown satchel slung on her right hip (where she holds her Bible), and brown boots with black straps in an X-shaped pattern. She also wore a silver cross necklace around her neck (she was later forced to remove it after becoming a Devil).
Upon transferring to Kuoh Academy, she wears the Kuoh Academy girls' uniform, albeit with a black sweater vest over her dress shirt in place of the cape and corset which has become her current main attire.
Asia is extremely shy, innocent and fairly inexperienced in things like socializing. Despite being reincarnated as a Devil, Asia still believes in God and follows his teachings such as praying to him and reading the Bible, which would usually result in her getting severe headaches. Even when she was still a human, she harbored no hate towards Devils and treated everyone equally, regardless of what they were. Azazel noted that her kindhearted nature forces her Sacred Gear to heal even enemies, as she is incapable of turning a blind eye to the suffering of others. Asia was also in deep shock when she learned from Kokabiel that the God of the Bible was killed during the Great War.
While initially having difficulty adjusting to her new life as a Devil, she has stated that she has found more important things than her faith in God, those things being her new friends, comrades as well as Issei's parents and Issei himself.
Asia is noted to be a very pure individual as people are drawn to her and that she is easily liked by others. Her charm and purity is such as that she was able to tame Rassei, a Sprite Dragon despite being a Devil as normally Sprite Dragons aren't tamable by Devils and are only tamable by those with pure hearts. Azazel noted that she had outstanding talent for taming dragons, as after receiving Ophis' blessing, she was able to form a contract with Fafnir, one of the Five Great Dragon Kings. After she managed to tame 4 mass-produced Evil Dragons, her name was spread in the world of Dragons due to the fact that only Evil Gods were able to tame Evil Dragons, as she became known as the Dragon Priestess (龍の巫女, Ryū no Miko) among Dragons.
Due to having to give away her panties each time she wants to summon Fafnir, she has become very embarrassed due to seeing Farnir eat her panties to the point of escaping from reality, lamenting that she has become associated with panties. However, after seeing Fafnir's resolve to protect her against Rizevim, she has become a bit less embarrassed by it and can put her shame aside during battle when Fafnir is fighting for her intensely.
Asia has a love of agricultural work as she often does gardening and planting. She has even stated that she would like to live with Issei in the country side of the Underworld and do cropping along with other kind of agricultural work.
Asia became more "bold" in her relationship with Issei when the other girls start being intimate and dislikes the idea of being left out. Due to Issei initially viewing her as more of a sister due to his desire to protect her, he didn't ogle her like he did other women, causing her to be sad and develop a bit of a inferiority complex when comes to comparing her looks to the likes of Rias. However, she will get jealous and pinch his cheeks whenever he lusts over other girls. She is shown to desire to be treated as a woman by Issei and to have his erotic behavior directed at her, as she has even shown a desire bear his children. Asia thinks very highly of Issei and has stated a desire to stay with Issei forever, even being willing to become his servant. Despite being shy, she is shown to be protective of Issei as she will slap someone like Diodora when they insult Issei.
After becoming Issei's servant, she has begun to shown more courage and determination in battle, as demonstrated in the Rating Game against Team Rias Gremory, where Asia stayed behind to fight Crom Cruach alone to allow Xenovia and Irina to proceed ahead as well to preserve Issei stamina, with Crom Cruach admiring her courage and guts. During the fight, she even displayed the ability to use magic offensively, in contrast to her past passive self, as she continued to fight Crom Cruach even after Fafnir was defeated, stating that as the servant and future wife of the Red Dragon Emperor, she would keep fighting until the end, which deeply impressed Crom Cruach as he praised her courage and spirit, stating that it was his honor to fight her and Fafnir.
In the past, Asia was abandoned by her mother in front of a church as an infant and was raised there. Sometime, during her childhood, she had awakened her Twilight Healing to heal an injured puppy she discovered, which was witnessed by one of the Catholic Church members causing her to become symbolized as the Holy Maiden. But, in all that time she didn't have either friends or people to talk to since most people viewed her as a monster who could heal wounds.
At some point, Diodora Astaroth devised a plot to have Asia heal him, a Devil, and cause her banishment from the Church with people labeling her as a "witch". With no place to go, Asia had to rely on the Fallen Angels.

Dragon Tamer: She's shown to have the talent of compatibility and outstanding luck with Dragons, as she made a pact with a baby Sprite Dragon, Rassei, whose race is notoriously untamable. After receiving Ophis' blessing, her compatibility increased, and she made a pact with one of the Five Dragon Kings; Fafnir. Asia was able to make a pact with four mass-produced Evil Dragons who were named Anselmus, Cyril, Gregorios, and Simeon, which is an act that only Evil Gods were able to do before.

Twilight Healing (聖母の微笑, Towairaito Hīringu): Asia's Sacred Gear and her main weapon of choice, she can heal Humans, Devils, Angels, and Fallen Angels alike. Since she has shown no actual combat skills, she relies on her healing abilities as a healer of her team. Asia learned how to expand the range of her healing field and send her healing powers as a projectile, although these are inferior to actual touch. In Volume 11, Azazel has said that she mastered her Twilight Healing more than other possessors in healing powers and time. She can also create a bow and arrow of healing power, and if the arrow is about to hit an enemy, it will disperse instead of healing them.

Asia's Balance Breaker takes the form of a Golden Dragon Armor with red jewels that cover her body and grants her a field of absolute defense and protection. For a limited time, Asia can cover a field with tremendous healing energy and can negate any damage from virtually any sources. It does not negate the attack but rather it negates the damage that the attack would inflict. As Fafnir's aura is included as well, it also boasts immense defense on top of the healing ability.
Bishop Piece (僧侶の駒, Sōryo no koma): Asia was reincarnated using the Bishop Piece, which grants her enhanced magic power.
