Youjo to Scoop to Maganou

Tsuguto Sumihara is way too nice...or rather, was too nice. He lost his life in a bus accident after being bullied into giving up his seat, and somehow was reincarnated into a mining camp! Not only that, the mine is at the base of an impossibly tall tower. It's there he meets the ram—horned Loulier, his first friend in this bizarre land. But when she's bullied, Tsuguto finds that maybe he wasn't reincarnated without powers after all...and that, if he's to have a future in this strange new land, Loulier's just the partner he needs.
