Source: Gonna be the Twin-Tail!! (Anime / Light Novel)

Character Description:
Iisuna Anko, also known by her codename Dark Glass, is a character with a complex double life. Initially appearing as a quiet, glasses-wearing student, she secretly works for the enemy organization, Ultimegil, as a high-ranking researcher and tactician. Her design revolves around her long black hair and purple eyes, always complemented by her signature semi-rimless glasses. Her style transitions from a reclusive student in a tracksuit to her high-tech, slightly more aggressive "Dark Glass" form. Despite her dark affiliations, she has moments that lean into the "Idol" or "Twin-Tail" aesthetic, showcasing a versatile and mysterious charm.
