Yokoyama Mitsuko

Japanese name:

横山 みつ子

Mitsuko Yokoyama is a supporting character of Prison School and one of 1016 girls in attendance at Hachimitsu Academy. Mitsuko is the secretary of the official Student Council.

Appearance
Mitsuko is short and slim with a normal bust, has dark green hair, and emerald eyes. She wears her hair in a twin buns. Mitsuko is seen wearing the standard school uniform, without a tie, and sometimes dresses with an open collar and without the blazer when doing manual labour for the official Student Council.

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