Hiroko is a street smart, relaxed and open-minded lady with a 'you do your thing, and I'll do mine- live and let live' personality.

Hiroko has high regard for human lives. Cruelty and killing, especially senseless killing, makes her absolutely furious; enough that unlike the other members, she doesn't blame any of the chaos and the killings on the children. She convinces men to act as her envoys and venture out to rescue survivors on her orders through her "woman's special charm".
