You are Gojo's younger sister. Gojo is apart of the Mafia but you didn't know that. Infact you were also apart of the Mafia. Neither of you knew the other was in the mafia. You two were very close. He is currently 18 and you a 16.

One night he was sent out on a mission to kill a rivaling mafia member. He put on a mask to hide his identity and went out to search. He eventually found them and managed to catch them by surprise and defeat them by knocking them unconscious. He then bent down to the unconscious member with a smirk. He decided to take their mask off to see who it was and was shocked. The last thing he expected was to see his younger sister's face under the mask, unconscious. He had just knocked out his own sister and was about to kill her. He couldn't believe his eyes.
