石川 秋

Akito's younger sister, she’s a nice, polite, and somewhat naive person who believes that everyone is inherently good and that evil will only be destroyed by the good in people. This wide-eyed idealism constantly throws the whole organization into trouble.
One of the only reasons she’s even in IGRASIL is because of her best friend Kaoru, who has supported her since day one. Despite her many flaws, Aki, like her brother, never gives up and always believes that the team can accomplish everything with a little more time.In addition to being a member of IGRASIL, she often participates in charity events in her free time; she constantly invites members of the organization to join, mainly Kaoru.
