Summary
Seated at number 28, Itona Horibe is a transfer student whose primary objective is to assassinate Koro-sensei. He arrives at the school accompanied by his guardian, Shiro. Although Itona asserts that he is the younger brother of Koro-sensei, there is no evidence of a biological relationship between them. The sole physical resemblance they share is the ability to generate tentacles from their hair, a trait that mirrors Koro-sensei’s own powers. Driven by an intense obsession with strength, Itona is determined to surpass his current capabilities and achieve a level of power far greater than what he possesses now.
