Aikurō Mikisugi

Aikurō Mikisugi (美木杉 愛九郎) is Ryūko's and Mako's enigmatic homeroom teacher. Initially appearing dull and easily flustered, he secretly observes and aids Ryūko by leading her to Senketsu. It is later revealed he is working undercover at the school as a spy for the Nudist Beach rebel group.

Appearance
In his disguise, Aikurō looks like a middle-aged man with blue messy hair, with a bent back and a unsteady gait. His blue eyes are hidden behind large reflective glasses. When in his true persona, Aikurō removes the glasses and sweeps back his hair, revealing that he is actually a young and very handsome man. In both personas, he wears a white long-sleeved shirt with a black tie and brown jeans, though in his true persona, the shirt is worn much more loosely as Aikuro has a tendency to strip his shirt off and show off his body like a posing supermodel. In this modeling mode, Aikuro sports sparkles all around him and has pink-glowing nipples.

Personality
Aikurō can easily be described as flamboyant. However he can also be serious when he needs to. When undercover, he takes on the persona of a tired and unenthusiastic teacher.

History
He once worked as an assistant to Ryūko’s late father, Isshin Matoi, whom was one of the few that knew of the potential of the Life Fiber. After the death of Isshin, Aikurō received his letter that guided him to the whereabouts of the Kamui, Senketsu, and the task to give Senketsu to his daughter.

To learn more about the Life Fiber, he infiltrated Honnōji Academy and went undercover as a High school teacher.
