Sera Rokudou
Sera Rokudou is a senior student from the Aimafuchi High School in Adachi-ku, Tokyo. She is a strange, docile girl who rarely speaks. She is found by Aoi Misato on the streets at night, being groped by an older man; showing no emotion, Sera simply wanders off after Aoi saves her.
Afterwards, Sera loses her memory, and ends up living on the streets; although she still has power, she is no longer a threat, nor harbors any ill-will. She’s befriended by a group of homeless men, including Alan Claude.
