Marimo Jinguuji

Nationality: Japanese Affiliation: Hakuryo Hiiragi, United Nations Army Yokohama Base, IJA/MDF 1st Battalion Rank: Sergeant, Major TSF: Type-77 Gekishin, Type-94 Shiranui

English teacher at Hakuryo and class 3-B's homeroom teacher, called "Marimo-chan" by Takeru. She can be ditzy and a bit of a nag, but has a gentle personality. Popular with both boys and girls, Marimo is loved by all of her students.

She became a teacher along with her best friend from Hakuryo Hiiragi, Yuuko. She's always been somewhat of Yuuko's plaything as the subject of her jokes and schemes, and she often makes fun of how familiar Takeru treats Marimo.
