Asaka Takatou

After facing repeated setbacks in her job search, she found herself working at a secretive research institute. Assigned to care for a boy known only by the codename 'ΑΩ' within an underground facility, she stood apart from everyone else by showing no fear of his instant-death ability, choosing instead to treat him as an ordinary child. By giving him a name and instilling in him a sense of ethics, she became the pivotal figure who shaped Yagiri's character and guided him toward restraining his own power.
