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.
Akaya felt something strange when his punch landed on Yakuzan. It wasn't entirely unexpected, so in a way, his suspicion had turned into certainty.
(Just as I thought, Yakuzan-senpai. It feels... hard. Like I'm punching a block of metal.)
Seeing Akaya's surprised expression, Yakuzan gave a dry smile.
"Surprised? That's the secret to how I managed to withstand your iron ball, at least somewhat. Your attack power is way too high. If I took that head-on, I'd be finished... So, I showed off a new technique," Yakuzan explained.
"You really look like you want to say its name," Akaya commented dryly.
"It's called 'Nitrogen Creation: Nitro Artist - Solid Robust.' It's an intelligent technique that compresses the abundant nitrogen in the atmosphere to create both defense and offense," Yakuzan said proudly.
"That sounds... strangely familiar," Akaya muttered.
"Don't worry about the details."
