Possible-reverse-harem Stories

Her parents are dead, her brother ran away from home years ago, and she lives by herself in an abandoned building. She's an aloof girl who makes AllMates, and knows how to take care of herself- and her panda bear AllMate Orio, of course. With few friends, she's happy in a weird semi-sad way. Apart from a fucked up government and the strangers she is forced to be around, her life was simple. Haha...not anymore.
