I Was Reincarnated as a Devil, Would You Like to Make a Contract With Me? (WN)

A second chance at life comes with horns, wings, and a contract.

After dying in a hospital, a lonely young man awakens as Lept, a newly born devil in a strange world ruled by sorcery, monsters, and seven moons. Summoned by the eccentric magician Garmon, he becomes his apprentice and begins learning Magic, exploring an unfamiliar world, and discovering what it means to live as something feared by humanity.

But Lept isn’t interested in corruption or destruction.

He simply wants to live, learn, protect the people he cares about—and maybe enjoy his new life along the way.
