It's a cliché, and the protagonist is dressed as one of the most popular time travel characters now. I'm trying to create my own Sawada Tsunayoshi. What I admire the most is a tutoring work from a long time ago. I forgot the name, but he was also dressed as Tsunayoshi. In the end, he seemed to have escaped to China with 59, and Yamamoto entered the political arena. In short, that one is my favorite tutoring fanfic, although the writing style is a bit heavy.
In this article, Tsunayoshi's fire attribute is still Sora, but he will never become the leader. The protagonist does not have the character of Vongola Sora. The protagonist is just a mortal (in my opinion, the attribute of fire has no connection with personality). Many places will be different, and the specific details are still being conceived.
The protagonist's childhood will not have any (accent) intersection with Yamamoto and Hibari.
