Prologue
Denki and Eijiro follow Katsuki to a city area inside the arena. They walk out in the street and Seiji immediately attacks them. Eijiro pushes Katsuki away and gets hit with an attack that transforms him into a ball of flesh. Katsuki notices Seiji and challenges him to fight.

Seiji explains that Shiketsu students are obliged to wear their hats while working because their actions is crowned in tradition. He believes the importance placed on obligation and dignity make him a more focused and stronger hero than "vulgar" folk like U.A. students. Denki doesn't understand a lot of what is said and Katsuki plays it off by insulting Seiji's eyes.

Seiji respects U.A. and claims that students like Katsuki continue to ruin its dignity. Katsuki taunts Seiji for talking too much about obligation and dignity and says he needs to speak more with actions instead of words.

Battle
Angry, Seiji attacks with projectiles made of flesh. Katsuki counterattacks with his AP Shot: Autocannon move and blasts the flesh balls apart.
