Naruto: Immortality and the Eight Inner Gates [Double agent]

Sharingan? Mangekyo? Rinnegan? Rinto shakes his head and says: Let me tell you about Immortality + Eight Gates Formation. After transmigrating into the Naruto world, I escaped from the Evil God Cult to the Hidden Rain Village, only to be sent by Hanzo the Salamander to infiltrate the Hidden Leaf as a spy; Initially, it was supposed to be just three years, but after three years came another three, and then another three… It’s been almost ten years, Lord Hanzo! That old geezer Sarutobi has summoned me for the fifth time today, pressuring me to succeed him as the Fourth Hokage! Good grief~ I don’t want to be Hokage, I just want to go home and get married!
