Class 2-B Homeroom Teacher

This staff member's wardrobe pays homage to a classic of Japanese tokusatsu. His outfit echoes the uniform worn by the Science Special Search Party from the long-running Ultraman franchise, a visual nod woven into his otherwise ordinary teacher design.

Little of his inner character is shown, though he comes across as a by-the-book educator who manages classroom logistics. One running misunderstanding on his part is the belief that Seiko is Momo's mother, a mix-up he carries without correction.

During the events surrounding the Cursed House Arc, he prompts Jiji to greet the rest of the class and shares with everyone that the boy's parents are recovering in the hospital.

Later, in the Space Globalists Arc, a note reaches him from Seiko explaining that Momo will arrive accompanied by a foreign transfer student called Bamora. He chooses to assign her to Class C, the section that includes Okarun. When Momo and Aira protest the placement after learning of it, he informs the pair that the arrangement is final and not open to debate.
