i have a few i kinda came up with while prototyping some stuff

first one is dude ends up getting blackmailed to work in an office full of otherworldly creatures, kind of like a "reverse" isekai, so you have elves as accountants, a dwarf in a suit, necromancer neet programmer etc etc. i had a few stories and characters kinda fleshed out just for fun. no ending though.

second was based on nijiura fandom, where a girl dies and gets into the afterlife, but gets mistransported to this underworld fortress that's almost abandoned, with a few maids stationing it - turns out the fortress is a bastion for the souls to stay in the underworld and not enter other worlds again(the real worlds), think act 4 pandemonium fortress from diablo. the girls needs to gather the lost nijiura maids that all hold an aspect of underworld's power within themselves.

there were a few more, like a whole "kinda isekai" denpa story about shoolgirls, depression and suicide, but this is cringe enough, i suppose
