Zakuro has the super-human powers of most angels and wears a naval officer's uniform, as well as an eyepatch on her left eye for unknown reasons. She is unusually polite, addressing people with the formal "-san" suffix after their names rather than the informal "-kun" or "-chan". Calm and soft-spoken, she is quite proficient in battle. Her weapon is a wet towel called "Eckilsax" which can split into two or more for close combat, as well as stretching itself to bind opponents.
