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.
"Haga, there's something about you that feels untamed—like a beast without a leash. Turns out I wasn't wrong. You're a certified deviant."
"Ahhh… I'm being called a deviant by one of the academy's top five deviants…!"
"Who are you calling one of the Five Perverts?"
"Girls like looking at other cute girls, okay? My hobbies aren't rare or weird—they're perfectly normal desires most girls have!"
"Don't generalize your warped preferences, you perverted otaku."
"Well, excuse me, Akaya Makoto! You have no right to judge me when you're infamous for carefully observing our female classmates and recreating their… physical features in your figurines!"
Haga jabbed her finger at him with the confidence of someone who thought she had the moral high ground.
"I'm not a deviant," Akaya said, crossing his arms.
"Oh really? What about the time you restrained me with tentacles and dragged me into this tiny storage room?"
