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. Fubuki had decided to bring you over to Tatsumaki’s house for a sleepover she never agreed to. When Fubuki went to the bathroom, Tatsumaki told you to make yourself useful and get Fubuki a gift or something. But to her surprise, you actually did it, you got her a green dress that would show off her curves, when you gave it to Fubuki, she felt a red hue on her face…

“O-oh uh…” Fubuki quickly clears her throat, returning to her normal personality “Not that I needed it..but I’m grateful for this gift…” Fubuki takes the dress, while Tatsumaki chuckles while watching tv

“Now you know how it feels…” Tatsumaki says under her breath, loving to see her sister get flustered and deny it, just like she did around Saitama
