Arisa 2

A bizarre android female falls from the sky and crashes into Shinichirou's café, prompting her to register him as her new master. Even if helping with housework isn't Arisa's strong suit, she manages to blend in with his sister, Kotomi, at least until a new girl arrives seeking the Fire Bee. Fire Bee: Arisa is revealed to be the weapon Fire Bee Shinichirou's father was developing before he vanished after a series of sexual escapades. The military is now determined to get her back at any cost.
