Omg please help me! The manga is a heterosexual one and the story is mostly art like the characters are in an art school and there are two crazy characters one of them is a woman who is obsessed with drawing terrifying drawings also beating up men and has this huge drawing of the other crazy character in the manga who is a man who I dont really know that much about and I think he draws everything in black and white. There are other characters and one of them is this woman who draws men dicks and is like you know quirky and shy type and the other character is so fucking blank like that son of bitch is not interesting in anyways even he's art teacher is telling him that he's drawings are not emotionally or has feelings into them. Please if you know the name of it tell me!!!!
so basically its about this boy who gets decapitated and then this demon lord turns him into a demon and the boy has to train to become a stronger demon. The boy works at a “brothel” of sorts and becomes stronger and looks for ways to kill his demon lord.
