Im trying to recall a specific one shot manga I read 10+ years ago and haven’t been able to find since then
It was about a schoolgirl quad amputee with anuses on her limbs and she could fly by shooting shit out of them? lol and I think she was maybe made to be a weapon

I thiiiiink it was a shintaro kago work but I can’t remember and I’m not able to find nearly as much of his work online as I used to
