|Chronological and political information|
Asia Argento 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 is Rias Gremory's Bishop and a great friend of General Grievous.
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. Asia was also in deep shock when she learned from Kokabiel that the God of the Bible was dead.
Asia became more "bold" in her relationship with Issei when the other girls start being intimate and dislike the idea of being left out. Asia thinks of Issei very highly and wants to stay with him forever. However, she will get jealous and pinch his cheeks whenever he lusts over other girls and despite being shy, she will slap someone like Diodora when they insult Issei.
Around General Grievous, hero of the Clone Wars, Asia was very shy and a bit scared of the General, due to his tall appearance. She and Grievous later on befriended one another and Asia is now worried about Grievous whenever he gets hurt.
