Linde transmigrates into the body of a demon mage who was burned to death by a demon's axe. To stay alive, Linde has no choice but to summon his own demons.
Only, the demons I summon are all a bit strange.
The Minotaur demon turns out to be a grass-eater, the nightmare becomes a timid, bloodthirsty centaur, and even the succubus becomes a frigid female secretary.
The demons being weird is one thing. Once he escapes danger, Linde plans to earn a noble title, live off the fat of the land, and happily spend the rest of his life farming.
Then Linde discovers that this world is facing an apocalypse.
