Karma Akabane is a 16 year old student in Koro-Sensei's class 3-E of Kunugigaoka Junior High School, who had been suspended from school multiple times due to his violent behaviour. He is also one of Nagisa Shiota's best friends and has a mischievous and cunning personality. Karma may seem lazy, but he is on par with Gakushuu Asano from class 3-A academically and considers him his rival. He got downgraded for his rebellious and violent behaviour, but underneath it all he still has good values.
