Who could be the main character in an 'assassination classroom time travel fanfiction'?

One possible plot could be a student from the future traveling back to the time of the Assassination Classroom. They might use their knowledge of the future events in the classroom to change certain outcomes. For example, they could try to prevent some of the students from getting into dangerous situations during their attempts to assassinate Koro - sensei.

Koro - sensei could be a likely candidate. Since he has advanced abilities, he might be able to figure out time travel in some way. He could use it to try to change his own past or to better prepare the students for their future.

Karma Akabane would also be a likely main character. His mischievous and intelligent nature would have evolved over the years. He could be involved in some sort of high - stakes international work, using his sharp mind and combat skills. And of course, he might still have that competitive edge when it comes to his former classmates.

The author of Assassination Room was the Japanese novelist, Keigo Higashino.

The children of Nagisa and Kayano could be main characters. They might inherit some of their parents' skills and quirks. For example, Nagisa's son could have his father's stealthy nature.

The plot could center around Nagisa's relationships with the female students in the class. Since she has now become a girl, she might form a closer bond with them. They could start a girl - only club or group within the class where they share secrets and train together. However, this could also lead to some jealousy or conflict from the male students. Nagisa would then have to navigate through these relationship issues while still focusing on the main goal of assassinating Korosensei.

Well, perhaps a group of students time travel to a future where they see the consequences of not assassinating Koro - sensei in time. This could give them new motivation and strategies when they return to their own time. Or, what if Koro - sensei time travels to different points in the students' lives and helps them in ways that are not related to assassination, like helping a student deal with a family issue in the past.

Shun would also be a good choice. His calm and strategic nature would serve him well in the unpredictable situations that come with time travel. He might be more interested in exploring the historical aspects of Bakugan in different time periods and uncovering secrets that could benefit the present.

Kayano could be her best friend. They have a lot in common, like being part of the assassination class and having their own secrets. They could support each other during tough missions and share girl - talk moments.

I think Ruby and Nagisa would be a great pairing. Ruby is all about being a hero and has her own sense of justice, while Nagisa has been trained to be an assassin but also has a good heart. Their different outlooks could lead to some really interesting conversations and adventures.
