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.
Sasuke would probably be very guarded at first. He's not used to dealing with something so innocent and vulnerable. He might be suspicious of the baby's presence and think it's some sort of trap.
Sasuke would be furious. He's always been protective of Naruto in his own way. He would immediately start looking for her, using all his skills and resources. He might even go on a rampage if he thought Naruto was in serious danger.
On the other hand, Sasuke could be very stoic about it on the surface but internally be in turmoil. He might start to analyze his own actions and whether he had missed any signs from Sakura. He could also be the type to immediately start thinking of ways to win Sakura back if he realizes he can't stand the thought of her with someone else.
Sasuke might be initially surprised. He is used to the Sakura from his past, so seeing a different, more mature future Sakura could catch him off guard.
I think young Sasuke would have a very intense reaction. He was so consumed by his hatred for Itachi at that young age. A Sasuke vs Itachi fanfiction would be like a trigger for him. He would be eager to see how the fictional fight is portrayed. If Sasuke in the fanfiction is shown as strong, it might fuel his own ego and make him strive even harder to become powerful. However, if the fanfiction shows Itachi as superior, it could enrage him. He might feel that it undermines his own goal of defeating Itachi and he might even want to find the writer to correct their 'wrong' view.
One element is the lyrics. If the lyrics are about dark topics like death, ghosts, or curses, it can be scary. For example, lyrics that describe a spooky encounter with a supernatural being. Another is the tone of the rap. A slow, deep, and menacing tone can add to the scariness. Also, the setting where the rap takes place. If it's in an abandoned place like an old factory or a haunted house, it gives a creepy vibe.
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. It could also be about a relationship, not necessarily romantic, but one where Takemichi becomes a sort of moral compass for the group, and they in turn protect him from other threats in their dangerous underworld.
