In the private Hero High School, where young talents of dungeon explorers gather, Makoto Akaya enrolls, believing in his own abilities. However, upon discovering the gap between himself and his classmates, he realizes that he is the biggest failure in the school. Nevertheless, in the midst of despair, he encounters a skill tree that only he can use, and Makoto Akaya's life begins to change for the better.
Yakuzentaku tightened his fist, his expression exuding confidence as his signature technique, *Oxygenless Domain*, began to take effect. The air around the monstrous Tree Guardian grew thin as the oxygen levels plummeted, a suffocating silence replacing the ambient noise.
