Class seat number: 28
A transfer student obsessed with gaining power, brought in alongside his guardian Shiro. Itona's whole reason for being there is to kill Koro-sensei—though he's convinced he's actually the guy's younger brother, which nobody really buys. They don't look related, but Itona can sprout tentacles from his hair just like Koro-sensei can, which is admittedly weird. The whole "brother" thing seems to be more about Itona's fixation on matching or surpassing Koro-sensei's strength. He's driven by the desire to become more powerful, constantly pushing himself to gain an edge over both his supposed brother and anyone else who gets in his way.
