Mikako Satsukitane

The student council president at Sorami Junior High School. Her family has a long history of chivalrous conduct. She possesses a brain that rivals Eishiro Sugata's, and has a dark personality that enjoys thrusting others into trouble for fun. Her combat ability is also extremely high, handling all forms of combat from shooting to close-quarters battle. Notably, her Iron Claw technique, which she executes with a grip strength of 400kg, is a special move worth mentioning.

She and Eishiro have been childhood friends. The story mentions an old familial connection between the Satsukitane and Sugata families. In public, she calls him "Sugata-kun," but when they are alone, she calls him "Ei-kun," showing the depth of their long relationship. She harbors strong feelings for Eishiro internally, and was furiously jealous when Tomoyo, who likes beautiful boys, took Eishiro away, even though Eishiro was not interested in Tomoyo at all. In the anime version, there is a scene where she is in a wedding dress, snuggling up to Eishiro.

In the early part of the original work, she often does not appear in serious episodes, which greatly irritated her. Towards the end, she appears frequently in relation to Eishiro, and her appearances have increased in the TV anime version.
