Aika Kiryuu

Aika Kiryuu (桐生 藍華) is a supporting character in High School DxD.

She is a third-year student at Kuoh Academy, in the same class as Issei Hyoudou, Asia Argento, and their friends. She has a very perverted and teasing personality, often giving lewd or bold advice (especially to the "Church Trio" — Asia, Xenovia, and Irina) on how to attract or get closer to Issei in intimate ways. She enjoys mocking the Perverted Trio (Issei, Matsuda, and Motohama) about girls and popularity, while sometimes fanning jealousy toward Issei.

She wears glasses, has golden eyes, and brunette hair usually styled in side braids. She's human (later becoming involved in magic as an apprentice), and she's known for her sharp, unfiltered, and erotic sense of humor.
