i've read hellstar remina which was pretty good and army of one, i liked both of them but i don't get army of one too much
spoiler;
how the hell did she kill over 500 people and make them disappear within minutes? the whole coming-of-age event apparently had excessive security, did they just not have any cops in there, either? how did she string up like 80 people at a metropolitan center with christmas decorations with nobody there to notice? i remember one of the officials in the story suggesting it was 'extra terrestrial' so was that really it? how much did she spend on fishing wire? also why was the mother all 'don't come in here' at the end when it was the girl?
i also remember reading this one about swirls that caused everything to go to absolute stuff and drove people insane, i'm not sure but i believe that one was junji ito
