Mitsuko Yokoyama

Mitsuko is a beautiful, slim and short teenage girl with dark green hair that is tied in twin buns with bangs swept to the left side and emerald eyes.

She is seen wearing the standard school uniform, without a tie and sometimes dresses with an open collar and without the blazer when doing manual labor for the official Aboveground Student Council. She is often inadvertently seen with her skirt stuck inside her underwear.

Mitsuko is a extremely clumsy girl who befriends Gakuto due to their having embarrassing public situations in common. Like Gakuto, with her klutzy attempts at manual labor (and sometimes by sheer bad luck), she can start off huge chain-reaction accidents that usually result in minor injury for those involved.

Mitsuko displays a heavy interest in the histories of the Three Kingdoms, and displays 'otaku' behavior by staying in the library and collecting manga issues. Mitsuko has a shy and kind temperament.

Notably, she is the only Student Council member to hold no grudge against the Underground Student Council.
