Mankanshoku, Mako

満艦飾マコ

A second-year student who is quite attached to Ryuko. She is often taken hostage or punished by other members of the academy.
Because rank in the school determines one's living conditions, Mako resides in the poorer "slums" of the city with her mother, father (who is a back alley doctor), her delinquent younger brother, and Guts, the family's pet pug.
Mako is a very energetic lady, opting to greet people with an affectionate dive into them.
