Rin Nohara, Tobirama's Jinchuriki

Tobirama Senju died protecting Konoha's next generation and buying time for the few students he'd left behind. After death, instead of going to the Pure Land, he woke up in the inner world of a certain girl. Just like a tailed beast sealed inside a jinchuriki. Tobirama Senju initially only planned to figure out how to get back to the Pure Land, but along the way, he couldn't help helping the jinchuriki again and again. Flying Thunder God Technique... Senju strength... The places where he hid his explosive tags while alive... None of it stayed secret. Nohara, the new Sannin, the Purple Flash, Rin pulls down the same goggles Obito wears: "Let's go, Tobirama!" Tobirama: ...Use my title in front of outsiders! *Canon Rin! Still with a battle-and-power-up style, haha *The pairing is Obito! Theme: Never forget your original aspirations, and bravely move forward
