What Should You Pay Attention to When Changing the Job of a Shinigami to Become a Ninja?

First person warning. . . I dislike winter very much. I don't like the biting cold wind, my hands that can't be warmed, and my clothes that make it difficult to move around. It makes people feel uncomfortable no matter what. But I was born in winter, and was given the name of winter. Winter snow. Is my name. Even though I was calling such a name, I felt deep in my heart. . . Hate winter. It was on a winter day like this that someone asked me: Do you have any dreams? My answer: Drink strawberry milk every day. If you encounter something that cannot be solved, you can look for a time machine in place. So I became the Grim Reaper. He fought tooth and nail and fought to the death. It was the same scene again, the same annoying winter day. Someone asked me again: What is your dream? I won't be fooled anymore, I asked Him: Is it still like last time? He nodded slightly. I thought about it: Then be young. So I became a ninja = = Me:? ? ? Instructions for consumption: 1. Be careful when disassembling CP. There will be a mess of CP coming in, so be careful. 2. Got some weird stuff 3. The timeline is confusing, all members have single arrows, and there will be an if extra. 4. I write whatever I want, and you can read it as you like. No negative comments are allowed.
