Onka

A crazy girl who's made a bad name for herself, commonly deceived other girls into going with her to a certain nonexistent night club to never return... 

Luckily, the authorities were onto her though, as they recently managed to catch her after a great many months of hunting her and many losses, instead of throwing her into the dungeon, they stripped her down and tossed her into a certain Tentacle Root Den far outside of District VIII where she'll never have any chance of escape mentally break and suffer a fate far worse than death...
