Alright here is the spoiler

Spoiler

A guy got isekai'd as a dungeon boss/demon lord but he is weak from the beginning and he started off inside this cave on top of a mountain surrounded by a big forest

APPEARANCE

Spoiler

He looks like your everyday isekai'd guy black hair probably same looking hair as kirito in SAO
He got bat wings that he can hide/unhide whenever he wants

Im not sure if this is enough detail but if what i said above still doesn't hit you then let me know and ill shower more spoilers.
