Some characters might become more protective of Takemichi if the fanfiction shows him in a difficult situation. They would feel a stronger bond towards him, wanting to ensure his safety. However, if the fanfiction distorts Takemichi's character too much, it could cause some confusion and even a bit of a rift. They might start to question if they really know Takemichi as well as they thought.
Well, Mikey might be a bit surprised at first. He would probably be intrigued by the different scenarios the fanfiction presents about Takemichi. Draken, on the other hand, might be more critical and analyze how the fanfiction portrays Takemichi's growth and relationships. Mitsuya could find it interesting from an artistic point of view, seeing how the writer has used Takemichi's character to create new stories.
In bonten x takemichi fanfiction, the story could revolve around Takemichi trying to reform Bonten. He has a history of going back in time to change things, so it would be interesting to see him use his unique ability within the context of dealing with Bonten.

In Takemichi x Mikey fanfiction, a common theme could be their growth together. Takemichi's time - leaping ability can create really interesting storylines in relation to Mikey.

It's also possible that the fanfiction shows their shared dreams and how they strive to achieve them side by side.
No, he doesn't. The Tokyo Revengers manga doesn't have Takemichi's death. Instead, he plays a crucial role in the unfolding events and continues to be an important part of the story.
A common theme is redemption. Takemichi often tries to bring out the good in people, and with Bonten, it could be about redeeming the members from their criminal ways. Another theme is friendship. Even in a world of crime, the fanfiction might show how Takemichi forms bonds with the Bonten members.
The world would be in shock. The media would be filled with reports of his death. Civilians who had always seen him as a symbol of safety would feel vulnerable. There would be mass mourning in the cities he had protected.
Ryuk would probably just be amused. He is a Shinigami who has seen a lot in his existence. Fanfiction is just another strange human creation to him. He might chuckle at some of the more outlandish ideas in the fanfictions, like a character having superpowers beyond the Death Note.
Naruto could see death magic as just another form of power that can be used for good or evil. If he witnesses it being misused, he would be angry and try to stop those using it in a harmful way.

He would adapt his fighting style to incorporate defenses against death magic, like using his shadow clones to test its limits without putting himself in too much danger at first.
