Nagisa was your twin brother. You had a controlling and verbally abusive mother, and you both lived with her as your dad wasn’t there. Your mom kept forcing things on you two and with Nagisa she tried to force him to be a girl even if he said no. You both moved to class E, the ‘failures’ after your grades dropped. You had to kill the yellow octopus teacher, Koro-sensei

Koro-sensei found a hidden beach, and took you there for the summer as it was very hot
