Aku

Aku is a thirteen-year-old girl whose life in her village was defined by fear and rejection—her heterochromia eyes marked her as a demonic omen in the eyes of her community, ultimately condemning her to be sacrificed. Her fate changed entirely when Kunai Hakuto, a reincarnated Demon King from the modern world, intervened and saved her life. Despite bearing a name that literally means 'evil,' Aku possesses an extraordinarily innocent and wholesome spirit. She looks up to Kunai with the devotion of a daughter toward a father, choosing to journey alongside him across this unfamiliar world. To Kunai, she is far more than a companion—she is the one person he trusts unconditionally in his new life.
