Tsukimi is a light-skinned young woman of average height and build. She has dark hair worn in a bob haircut with a fringe. Like her teammates', her uniform emulates a basic tracksuit style, combining a high-collared, zipped sweater with a single white line running along its sleeves with darker pants and a black undershirt (maroon in the anime). Border's logo is located on the outer side of both sleeves, roughly around the halfway point of the humerus.
As a B-rank agent, Tsukimi should be individually more powerful than C-rank trainees. Her Squad is strong at standard tactics. However, all three members were single-handedly taken down by Yūmabefore they could show their true capabilities.
