Itona Horibe

Itona Horibe arrived at Class 3-E as its second transfer student, carrying a turbulent past as an assassin surgically augmented with tentacles by the shadowy organization known as 'White.' His obsession with raw power stemmed from the collapse of his family's manufacturing business. After his tentacles spiraled out of control and the organization abandoned him, Koro-sensei and the Terasaka group stepped in, removing the tentacles and giving him a genuine place to belong. Now fully integrated into the class, Itona contributes his sharp wit, unfiltered honesty, and extraordinary expertise in electronics engineering—serving as the team's go-to mind for mechanical development and covert surveillance equipment.
