My Neighbor Mitsuru -There's A Hot Young Guy Living in My Building
Ore no Tame Dake ni Naite
Sex and Dungeon
Humans level up through sexual acts... seriously, adventuring has never had these kinds of perks before... So it's a raunchy/sleazy premise on an interesting character base. Our MC is an adventure nut... and now that physical interactions are the only way to level up... Magical roofies are just the beginning...
Isekai NTR
I like that our MC is an Anti-Hero who is hell bent on protecting the hero from being used. I mean he's so jaded it isn't even funny, but he truly is very sweet and loyal in his own way. He still doesn't realize that he himself is pretty amazing. On another note, does anyone else feel like he might accidently become the demon lord?
