A soldier with the United Forces of Earth. She serves as Darzana's aide. A member of the UES Wadatsumi of the 4th Fleet Escort Force. Kaoru appears to be a practical and capable individual. Little is known about her personal life, except for the fact that she seems to be friendlier with Darzana Magbaredge than a CO and subordinate usually would be. She also appears to have difficulty entering romantic relationships, something Magbaredge occasionally teases her about.
