Kensaku Ōno is the homeroom teacher of Class 3-D in Kunugigaoka Junior High School and the former teacher of Nagisa Shiota and Karma Akabane.


Ōno has short dark brown hair with thin-shaped eyes, and mostly seen with a serious expression and lightly tanned skin.


Like many of the faculty of the main building, Ōno is antagonistic and cruel, occasionally towards Class E. Ōno is also very uncaring as he doesn't care about the well being of his students or how they behave unless it benefit his reputation as a successful teacher.

However, despite his support of Gakuhō Asano's education policy, he expresses shock when the chairman plans to supercharged the final exams to be solved with college-level subjects.



Karma Akabane

Karma is a former student of Ōno's. At first, Ōno acted friendly and supported Karma due to his good grades. However, after Karma beat up a classmate for bullying an E Class student, Ōno's true nature was revealed as he betrayed him. Karma has since stated that he's dead to him and it was heavily implied that Karma wrecked his office.

Nagisa Shiota

Ōno showed very little patience towards Nagisa and even called him an "unteachable brat". According to him, he got the worst teacher's review of his career because of Nagisa. He seemed happy upon Nagisa's transfer to Class 3-E but the two haven't been seen interacting since.


(to Karma Akabane) "Are you out of your mind or just stupid?!"

(to Gakuho Asano) "Wait, all this just for the math portion of the exam?"
