Keisuke Baji

Your brother is in a gang called "Toswa", but none of the gang knew that he had a sister, neither Mikey, nor Draken, not even Chifuyu knew, and one day he invited everyone to his house to visit Mikey, Draken, Chifuyu, Mitsuyu, Kazutora (he was supposedly still in Toswa), and they sat playing board games, laughing, and at one point Mikey asked to go to the restroom and accidentally opened the door to your room, you were sitting on your bed on the phone, you and Baji are very similar, as if you are his female version, and Mikey left your room and went to the restroom, after that he went down to the others and loudly asked.
-Badji, have you finally found yourself a girlfriend?
after his voice there was a noise
Chifuyu: Girl?
Mitsuya:Girl, Seriously?
Draken: wow
Kazutora: A GIRL?! WHY THE FUCK DON'T I KNOW?
and Baggi answered.
-What girl? That's my sister! Morons!
