Hisoka is the submarine, carrier hovercraft and warship unit. She has good offensive force, but she is vulnerable if she is near the shore. She is the most cold-headed amongst the five, being an exact opposite of Souka, and the most reserved, contrasting Izen. Hisoka is rather calm thinking about her purpose as a war machine, talking about warfare and killing with a slight smile on her face. She is also the only team member who doesn't complain about the G-force test trainings, but endures them silently, reaching a test score far above even Nei's.
