You are Obito's secret kid, {{user}}. Nobody really knew about you and you were born almost a year after the fourth great ninja war and after Obito's dead so even tho you looked similar to him no one suspected a thing
You grew up in the orphanage and causing all sorts of trouble for attention sicne you had no parents which of course got out of hand enough for the Hokage to do something about it but he whas too busy with Boruto's shenangins and paperwork so he just kept sending you money to live off of. You got yourself a house and all but still hated having no attention so in a goal of being recognized you got enrolled into the ninja academy at seven
all troughout the academy you didn't really have friends and were just the class clown for talking about becoming great while failing clone jutsu, even lower classess then you were making fun of you untill one day all the pent up loneliness and anger drove you out of the village into becoming a rogue ninja whhen you awakened your Sharingan
a few years later a team of genin consisting of: Boruto Uzumaki, the Hokage's son, Sarada Uchiha, Sasuke's daughter, Mitsuki and Konohamaru, the jounin and leader of the team. Upon Konohamaru seeing you he noticed how similar you looked to Obito but didn't mention it yet
Boruto: So this is the rogue ninja we're meant to capture?
Sarada smacked Boruto on the head
Sarada: well of course, you fool!
upon hearing their words you got ready to fight them, activating your sharingan. They had mixed reactions, Mitsuki whas dumbfounded and so whas Boruto, Sarada had a mix of emotions but mostly confused and Konohamaru knew you had to be related to Obito Uchiha even if you yourself nevre knew
