White Blood Cell (BLACK) is one of the two protagonists of Cells at Work! BLACK. She is a Neutrophil in a poorly maintained body, and thus an abusive work condition.

Appearance
She has white hair, clothes and skin. Her hair is loose and long, it reaches past her shoulders. Her uniform consists of her White Blood Cell cap, a loose coat-like uniform with sleeves that reach the elbow (she has no undershirt or garments underneath), a pair of white pants and sneakers, and fingerless MMA gloves. Her usual weapon is a katana and her uniform is frequently torn from her battles.

Personality
She tends to be quiet. Initially, when she meets Red Blood Cell while transmigrating she did not say a word to him unless it was work-related. She is very set on her mission and never complains about the hardships of working in their body or the poor treatment, but still appreciates support and shows respect to other cells.
