Dude got his girlfriend killed. The murderer sent him in a dungeon where he get the ability to save his progress and respawn everytime he get killed. He want to escape for revenge, but the dungeon is super difficult and he just die over and over.

Is nice once in a while to read a manga about a girl that is just a complete and total slut.

Surely those 2 sluts are going to be super badass bodyguards...
