Genius Corpse-Collecting Warrior

Briefly about Genius Corpse-Collecting Warrior manga:

It has already been two years since I possessed a character in this insanely difficult game. In order to go back to Earth, I have no choice but to stop the downfall of this world and reach the ending of this game. [You have collected the body of a “pathetic soldier.” Inheriting abilities.] [Inherited rewards: Stamina +1, Proficiency +1, Dehaman’s Armored Combat (D)] I will see through to the end of this game no matter what!
