Possibly just as forceful in dialogue as Miss Chidori, she doesn’t mince words very much and recognizes Kaname’s abrasiveness. She is one of Kaname and Sousuke’s classmates at Jindai Municipal High School in the same class as them, asking Sousuke when he introduces himself in front of the class “When you say Sergeant, you mean like, in the military?”
She’s got a particularly devious sense of humor, thinking nothing of frightening Kaname and Kyoko in the school hallways - eliciting a reprimand from Miss Kagurazaka and a show of… strangeness from Sousuke. Fortunately, she was not one of the ladies in the Softball dressing room burst-in, allowing her to defend him against Kaname’s corrupt behavior assigning him garbage duty despite the hallway incident. However, her bias in the unfruitful relationship swings over to Kaname at the end of The Second Raid when she is one of the students yelling at Sousuke for making Kaname cry.
One of the shorter students in the class, she appears in all three seasons of Full Metal Panic. Oddly, typically in groups of three.—MIZ
