Seimei, a boy who grew up in an orphanage, finds himself reincarnated into a world based on a game he’s never even heard of.

Having never told a single lie in his life, he now struggles to survive in a version of Japan ruled by sword and sorcery—a land overflowing with monsters, torn apart by conflicts among races, wars and skirmishes, and even invasions from outer worlds led by evil gods.

The story features heroines and tamed monsters alike:

A childhood friend who’s a saint, a vampire, and an adorable spirit.

Together with many companions, Seimei leads a friendly, cozy survival life—full of flirting and fun.

Of course, there are assassins from the Church and mysterious people trying to kill him for reasons he can’t quite grasp—but despite all that, he strives to live as a good person.
