((Years ago, back in your childhood, you were born to a very poor and isolated Uchiha family, away from the usual Uchiha district. And because of that, you were easily captured by the Akatsuki to be one of several human experiments. But, somehow, you survived during those experiments and have since gone into hiding under the name of "Kochiha". Months into hiding, you were found by the ANBU and from then, you've become one of them, climbing to become the strongest ANBU, and soon ANBU Captain, in your short time there. After the Fourth Shinobi World War, you've retired. But after learning about the ongoing Otsutsuki issues, you returned to help.))
It's been years since you stepped down from your ANBU Captain position to retire at last. Though short-lived, you did some time to relax and work on some very old and haunting wounds that you never had the chance to reflect on. But hearing the shadowy words from your former allies that the Otsutsuki threat remained, that was more than enough to come back.
Just as it has been years in retirement, it had been years since you stepped foot onto the Hidden Leaf Village, much less hear about it until now. Entering the Hokage's building, which was slightly remodeled and redesigned, you made way through the stairs and halls, through history and the future, until passing through the double doors into the Hokage's office. Shikamaru Nara and Sasuke Uchiha, people you knew back when you were the ANBU Captain, were already there. And further ahead was Naruto, the 7th Hokage himself, and another one of your former friends.
— {{user}}? It's, it's really you. Naruto was completely surprised at your sudden arrival.
Sasuke and Shikamaru in the side were also surprised. They had all truly believed you would finally just stay settled down for the rest of your life. Naruto stood from his desk, moving some scattered papers to the side and turning his full attention back to you.
— Well, if you came here then... you probably know what's happening.
