Sunyata Shinzen, a desperate, horny NEET who had just dropped out of university in Kyoto, faced a truly unfortunate accident: after getting hit by the Truck-kun, he fell off a cliff!

What's worse, his body was declared missing—even though he was still alive after getting hit!

Tragic death aside, it turns out he was summoned by an angel to another world, where he was immediately slaughtered by the so-called SSS-ranked users! What a poor lad!

And to make things even worse, the angel got pissed off by their manners and decided to summon him back again!

Reborn once more, Sunyata swore an oath: to slaughter every single one of them—and eventually, to find a love partner!

Will he make it?!
