Synopsis: The Three Skills I Received, When Combined, Were The Most Powerful

Mutou Kushina's life, filled with brutality, came to an abrupt end. In his new incarnation, the goddess granted him three abilities: [Super Speedy Regeneration], [Agelessness], and [Grit: Indomitable Spirit]. However, those skills were outlier skills that were not offensive skills! The place where he was reborn with such skills is the Forest of Endless Calamity, where a large number of Danger Level S monsters roam, one of which is capable of destroying the world. Having no offensive skills, Kushina's should have been killed by the monsters right away, but...? With all three skills, he can instantly regenerate no matter what kind of attack he receives! And every time he is attacked, he gets stronger and stronger...
