Ume Mizunoe 水之江梅

First-year student in Class 2 of the Fujinari Academy High School division. Student council secretary. Member of the Handicrafts Club.

An academic standout with exceptional grades in liberal arts subjects and a track record of winning literary awards.

Conversely, his performance in science and math subjects is abysmal—even recording single-digit test scores—putting him at risk of failing to advance to the next grade. As a result, his homeroom teacher, Satomi Hiratsuka (Biology), warned him that his grades would negatively impact his academic record and suggested he join the student council.

He acts as the "straight man" (tsukkomi) of the group; he is the voice of reason who calmly resolves comedic situations that would otherwise spiral out of control—situations that the President would simply let slide or that Arisu would resolve with physical force.

Thanks to his helpful nature and pleasant personality, he becomes well-liked by people both within and outside the student council.

He tends to reveal a "troublesome otaku" side of himself when the topic turns to literature, though such moments became less frequent as he was swept along by the eccentric personalities around him.
