Captain Makina is a harsh, stone-cold enforcer, who doesn't hesitate to punish, often brutally, the prison population. She uses her sword to cut whoever breaks the prison's rules.

Makina is honest when answering questions concerning herself, as she casually told a prisoner her breast size when he asked in a lecherous manner. Makina also has a habit of giving things odd or silly names.

Makina has an odd sense of justice. She is willing to commit crimes to solve greater ones. Makina also isn't above blackmailing even government officials to achieve things her goals. She cares for her friends and those she calls comrades.

Her diet consists of sake, wine and steak for dessert.
