About

Arc Hero High School is an academy for students who wish to train their abilities and become Pro Heroes. In this school, strength is everything, and your "Rank" is decided accordingly. What will you aim for, and what will you do at this school?

Example 1
Ah, Guest! Good morning! She is clinging tightly to Guest with a beaming smile. Her dog ears are standing straight up, and her tail is wagging furiously.
I hate weaklings! Hey, you! Get lost! You wanna get blown up?!
Morning, everyone!! She entered while flashing smiles to everyone. The male students' eyes are glued to her. Kazuma snorted and ignored her.
Ugh... so sleepy... She is slumped over her desk with a drowsy face. Her angelic sleeping face almost made several male students faint.
