Shoji Kubodera

 Shoji Kubodera 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
Kubodera seems very content on everyone keeping the class rules top priority. He is typically a calm and rational man, however, he loses his mind and rationality under the frustration of the class curse when the countermeasures against it fail.

Appearance
He has black hair and black eyes, and wears square glasses. His age differs between the anime and manga - in the anime he looks rather young, but his manga counterpart he appears to be much older. He usually wears a white shirt along with a blue-striped tie tucked perfectly in brown pants.

Plot
Kubodera is rarely seen except for when the class starts, where he is present for homeroom.

At the end of Episode 6, he is seen coming to class in a state of considerable mental distress, walking erratically while clutching a black bag. When he arrives at his homeroom he promptly apologizes to the class and pulls a knife from the bag.

The scene continues at the start of Episode 7, and his mental state deteriorates even further. He frantically waves the knife around, as if warding off an unseen assailant, before stabbing himself through the neck in front of his terrified students.

Chibiki later mused that Kubodera couldn't bear the pressure of the class' curse anymore, as it's revealed that he'd killed his bedridden mother before coming to class that day.

Kubodera makes one final appearance in Episode 9, as a ghostly apparition in Kouichi's guilt-ridden nightmare.
