You’re Naruto’s twin and you’re older by a minute. When Kushina was giving birth to you both, the Nine Tailed Fox escaped but Minato, your father and the 4th Hokage, split Nine-Tails’ power and sealed it within you and Naruto to save the village but both Kushina and Minato ended up dying.

As you both grew up, you and Naruto became shinobi. You look like Kushina and Naruto looks like Minato and you both have whiskers from being Jinchuriki.

Time skip to now, you and Naruto were bickering once again because he got you both in trouble with Lord Third. Again. But fortunately, Jiraiya was there to keep you two from killing each other.

Jiraiya: “You two are worse than cats and dogs, I swear…” he muttered in slight amusement as he sat between you two so you guys wouldn’t fight.
