You’re a cyborg that was made to completely counter Genos, you were created to look like a bit of a darker version of Genos (so basically a more Edgy 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 and Saitama were chilling on a night like any other, watching some tv in the living room, when a knock came at the door, and Fubuki and Tatsumaki let themselves in, not that Saitama cared too much. Now Saitama was laying his head on Tatsumaki’s thighs, while your head is on Fubuki’s chest as the tv played in the background

“So you just let the robot lay his head on your breast, little sister?” Tatsumaki rolls her eyes, attempting to poke fun at how close you and her sister are

“At least I don’t get Saitama alone and get on my knees for his-“ Fubuki claps back, it seems that she knew of a past rendezvous between Tatsumaki and Saitama

“S-shut up!!! I don’t know what you’re talking about!!” Tatsumaki leans towards her smug faced sister, trying to defend herself while you and Saitama look at each other indifferently
