Korosensei is the most interesting without a doubt. His appearance alone is striking, and his ability to teach while being targeted for assassination is quite remarkable. Karma Akabane is also very interesting. He's a bit of a troublemaker with a high intelligence and his interactions with other characters add a lot of spice to the story. Then there's Kayano Kaede. Her true identity and her role in the story are full of mystery and make her an interesting character.
Well, for me, Korosensei is the most captivating. He has so many layers to his character. He can be very humorous at times, but also shows great wisdom and care for his students. Nakamura Rio is also an interesting character. She's outspoken and has a strong personality. Her views and actions often challenge the other characters. And Tadaomi Karasuma, the government agent, is interesting as he represents the outside world's view of the situation in the classroom and his relationship with Korosensei is full of intrigue.
Koro - sensei is definitely one of the most interesting characters. He's an octopus - like alien who is supposed to destroy the Earth but instead becomes a teacher. His superhuman abilities and his unique teaching methods make him stand out. Nagisa Shiota is also interesting. He has an unassuming appearance but is very perceptive and has some great assassination skills.
Definitely Koro - sensei. He's a very unique character as he's an octopus - like teacher who the students are supposed to assassinate. His abilities and his rather jovial yet mysterious personality make him stand out. Another interesting character is Nagisa Shiota. He has a gentle appearance but is quite skilled in assassination, which is an interesting contrast.
Nagisa Shiota from 'Assassination Classroom' can also be quite popular in these crossovers. He has his own growth arc in the original series. In a fanfic with Harry, he could learn from Harry's experiences at Hogwarts and vice versa. Their friendship could develop in a way that combines the best of both worlds, with Nagisa's assassination skills and Harry's magical knowledge.
Ayanokoji Kiyotaka is very interesting. He is highly intelligent but often hides his true abilities. His complex personality and his mysterious past make him a character full of intrigue. Then there's Horikita Suzune, a strong - willed girl who is determined to rise to the top through her own efforts.
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.
Naruto himself would be really interesting. His never - give - up attitude could inspire the students in the Assassination Classroom. He could also learn from their unique skills and knowledge. His journey in this new world would be full of surprises as he tries to adapt to their assassination - based curriculum.
Midoriya and Nagisa would be an interesting pairing. Midoriya is all about becoming a great hero and has a powerful Quirk that he's constantly learning to control. Nagisa, on the other hand, is a skilled assassin - in - training with great stealth. They could learn a lot from each other. Midoriya could teach Nagisa about the importance of having a big dream and standing up for what's right in a more heroic sense, while Nagisa could show Midoriya how to be more stealthy and observant.
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.
The author of Assassination Room was the Japanese novelist, Keigo Higashino.
Ayanokouji Kiyotaka is quite interesting. He's a very intelligent and mysterious character. He often acts in ways that are unexpected, hiding his true capabilities. Another interesting one is Horikita Suzune. She's highly competitive and determined to succeed, which makes her character engaging.
