Naruto: Retire the Shinigami and Rebuild the Ninja World

Yuuto Fuyuki was just a retired Shinigami. Originally in this world, he only wanted to discuss Tao with King Yama and tease the little toad, little white snake and big white slug. However, after he came out of the Pure Land to discuss Tao with King Yama, he found that the world had changed and he couldn't understand it. Ninja? Chakra? And a group of tailed beasts? Fuyuki Yuito took a closer look and found out that he had not entered the wrong world, it was still the same world. Well, it seems like this new world is okay? "Orochimaru, it might hurt a little later, everything will turn into ashes, and the blade will flow like fire!" "Tsunade, don't be sad, look at these scattered Senbonzakura, how beautiful they are!" "Xiaonan, how many times have I told you, this is not how Sode Shirayuki is used!"
