Sumi Otokawa

Sumi Otokawa is an upperclassman at Misato West High School who rose from Student Council Secretary to become its President. Heavily influenced by her grandfather, she speaks with a distinctive archaic flair, often ending her sentences in a quaint, old-fashioned manner. She harbors an unusual fondness for collecting fake mustaches and a peculiar habit of touching other girls' chests. Despite these eccentric quirks, her warm-hearted nature and sharp perceptiveness have earned her the deep trust of her juniors, making her an indispensable supportive figure who quietly watches over the main cast.
