Another storyline could involve a character from Assassination Classroom being sent to the KHR world. Nagisa, with his assassin skills, could get involved in the mafia - like affairs of the KHR universe. He might use his stealth and combat abilities to help out the good guys in that world, or perhaps he gets caught in the middle of a power struggle between different mafia families.
First, understand the personalities of the characters from both KHR and Assassination Classroom. For example, Reborn from KHR is a strict and somewhat mysterious tutor, while Koro - sensei is a fun - loving but deadly octopus - teacher. When creating an interaction, think about how their different traits would clash or complement each other. Maybe Reborn would be intrigued by Koro - sensei's unique abilities and try to find a way to use them for his own training methods.
In Karma x Reader fanfics of Assassination Classroom, the fanfic writers often take advantage of Karma's popularity. They create stories where the reader - character is attracted to Karma's confidence. Some fanfics focus on how the two would communicate, like the witty banter that might happen between them. The world of Assassination Classroom provides a rich backdrop for these stories. There could be elements where Karma uses his skills to impress the reader - character. Moreover, the emotional aspect is important too. How the reader - character makes Karma feel more vulnerable or how Karma's actions affect the reader - character's emotions are often explored in these fanfics.
One possible plot could be that the students from Assassination Classroom are sent on a mission to the world of KHR. They could end up having to help the Guardians in a battle against a new and powerful enemy. Tsuna and his friends would be initially suspicious of these strange new allies but soon realize their skills and unique abilities can be of great help.
One great 'Karma x Okuda' fanfic is 'A Different Kind of Bond'. It beautifully explores their relationship development. The author does a wonderful job of portraying Okuda's shy nature and Karma's mischievous side in the context of the story.
Itona in the Assassination Classroom fanfic is often depicted as a complex character. He has his own unique backstory and growth arc. His relationship with other characters, like Nagisa and Karma, can be explored in different ways in fanfics. Sometimes he is shown as a more vulnerable side, which is different from his tough exterior in the original anime.
Well, Maehara in fanfics related to 'Assassination Classroom' can be quite interesting. He might be the center of a romantic sub - plot. Some fanfics could focus on his growth as a character, perhaps from being a bit of a class clown to someone more responsible. His skills in assassination, which are not as prominent as some other characters in the original work, might be enhanced in fanfics to give him more of a role in action - oriented scenes.
In fanfic, Karasuma can be a source of stability for the students. He is not only teaching them assassination techniques but also life lessons. His no - nonsense attitude can be a guiding force for the students, especially when they are faced with moral dilemmas in their training. For instance, when a student has to decide between a quick kill and a more humane approach, Karasuma's influence might come into play.
Karasuma in fanfic can be seen in various relationships. For example, his relationship with the other teachers and how they collaborate to handle the students. His interactions with the students also show his growth as a character. Sometimes, fanfic writers explore his past, which may not be fully revealed in the original work, adding more depth to his character.
Definitely Nagisa. In the crossover, he could be the one who has the hardest time adapting to the new world of KHR. His assassin skills would be put to the test in a different way compared to Assassination Classroom. He might form an interesting friendship with Tsuna, as both are somewhat timid at first but have great potential within them.
