Shoji Kubodera

He is the homeroom teacher of 9th Grade Class 3 at Yomiyama North Middle School. He and his mother are two of the "Deaths of July".

Personality
He seems very content on everyone keeping the class rules top priority. He is seen losing his mind under the frustration of the class' curse, when the countermeasures didn't work.

Appearance
He has black hair and wears spectacles. In the anime, he looks a bit young whereas in the manga, he appears rather old. He used to wear a white shirt along with a blue tie tucked perfectly in brown striped pants.

Plot
Kubodera is rarely seen except for when the class starts, where he is present for homeroom. In episode 6, he is seen coming to class in a messed-up state and proceeds to take out a knife, apologizing to everyone. He then proceeds to use the knife to commit suicide in episode 7.

Later, in that following episode, it is stated by Chibiki that he couldn't bear the pressure of the Class curse and killed first his seriously-bedridden ill mother and then committed suicide in front of the whole class. But it rather seemed that he was trying to ward off the hand which held the knife.

Mr. Kubodero was also the person who sugested that Mei Misaki be the one "who doesn't exist".
