After transmigrating into the Uchiha clan, he became Uchiha Itachi's younger brother and Uchiha Sasuke's older brother.
With Uchiha Sasuke about to start school, Uchiha Yan isn't worried in the slightest.
The ultimate little-brother-obsessed Itachi wouldn't hurt his adorable younger brother, would he?
He wouldn't... right?!
Since he won't die, all he has to do is pretend to be the ultimate big-brother fanatic, Itachi's number-one bootlicker. So why should Uchiha Yan worry?
Why should Uchiha Yan, who knows the whole story, risk his life to help Two-Timing Sasuke get revenge?
So what's wrong with staying quietly in Konoha and being a lazy fish, even if that means being an Uchiha in name only?
Are Pain, the Otsutsuki, Black Zetsu, and Uchiha Madara not terrifying?
Or is the Konoha bathhouse just not good for the Uchiha's ultimate eyesight?
Are foreign village ninjas, the Nine Tailed Beasts, and technology fanatics not scary when you have the Sharingan?
Or can't you get by in Konoha with the Uchiha clan leader's stunning looks?
What? The world is going to end?
Isn't Two-Timing Sasuke and his blond best buddy still around?
I, the only Uchiha in Konoha, have resolved to restore the Uchiha clan to greatness... Just kidding.
Being a lazy fish is nice for a while, and being a lazy fish forever is even better.
