Ishikawa-sensei
Summary
Ishikawa-sensei is a teacher who appears alongside the 5th Grade teachers, presumably serving as their gym instructor. He is characterized by his constant movement in a jumpsuit, messy hair, beard, and glasses. While he occasionally offers advice and shares knowledge based on his experiences, particularly regarding spiritual matters, he also acts as a bad influence by keeping cards from various porn shops in his jumpsuit pocket, a fact Nube accidentally discovers when items fall out of a borrowed suit. Although his official status as a 5th Grade teacher remains unconfirmed, his frequent presence with them justifies his inclusion here. He has a notable habit of going over a month without showering and harbors a fetish for wearing women's undergarments, which backfires when Minki, the sister of the Oni no Te from Baki, arrives from hell to reclaim them.
