Assassination Classroom - Koro Sensei plush

Although he looks like a big yellow octopus with a smiley face, Koro-Sensei is a teacher, and even the main teacher of the 3-E class. Normally, his color changes depending on his mood, but here it is yellow, so everything is fine. The students in his class aim to kill him in order to get a nice reward, but if you do not want to see him disappear, you can buy this stuffed animal and guarantee him a good life.
