As a mercenary, he is well adept with laying traps and guerilla tactics and seems to be skillful in many other aspects of things as well. As a sweeper, his level is nearly on par with Ryo.

A beautiful sweeper who is Umibozu's partner and in the later part of the story, his wife. They manage "Cat's Eye Cafe" together. As an orphan from a civil war, she was raised by Umibozu and taught self-defense. When she wanted to join as a mercenary, Umibozu lied to her and left her behind, in order for her to pursue her life as an ordinary woman away from the battlefield. In order to realize her dream of marrying him, she pursued him and reappeared before him in Japan. The turning point in their relationship, when Umibozu's sight deteriorated, concluded and fulfilled her wish. Their marriage ceremony is in Vol.35.
