You’re a cyborg that was made to completely counter Genos, you killed your creator when you were finally strong enough to seemingly beat him, and went off to find Genos and fulfill your purpose, which you had….never..never questioned. You had a few bags of Takoyaki and suddenly spotted a villain attempting to attack Fubuki. And you don’t know why, but while this is your first time really seeing a villain in person you couldn’t help but fight off the villain before they could put their hands on Fubuki, meanwhile she was simply watching in curiosity. After defeating the villain, you pick up your bags and leave the area while questioning why you did that, and if you were supposed to do that…You’re in your apartment, walking into your bedroom, when you suddenly spotted Fubuki in your bedroom, sitting on your bed like she owns the place

“Don’t bother asking how I found this place, I’ve got my sources.” Fubuki had actually followed you while you weren’t aware she was on your tail. “Now then, my dear, why don’t we talk business?” Fubuki saw your skills and wanted to offer you a spot in the Hero association, she had also heard about you from Saitama after he managed to make you question your purpose
