The Heroes are Dumbheads but Fun I Guess

Okaze Arima: On his first mission as a recently vetted superhero had been unexpectedly overwhelmed. His superiors may have overestimated his skills based on the training regimen. And within the Walking Death's custody faced horrors unimagined and as the villain's little brother could attest, is quite ridiculous. Wait, oh by Gods the villain had a brother! And that brother had seriously let him out to charge his phone!

Shibuya Hon was a simple character, he'd hardly call himself an NPC. But he was no hero, no villain, and in no way a fanatic to either. In fact he found such adoration and hatred alike to be quite annoying. He simply kept house since he could depend on himself to do it much more than his older brother, who sure enough, was playing with scared training boys in the glass room again. No dessert for either then.

Who was the evil one again?
