Description
Leucocyte 1212, designated U-1212, operates as a neutrophil within a poorly maintained environment characterized by demanding work conditions that impose significant stress and operational challenges.

She possesses short, fluffy blue hair and matching blue eyes. Her attire includes a standard neutrophil cap, a loose white coat-like uniform worn without garments underneath, white pants, sneakers, and fingerless black MMA gloves. She wields a katana as her primary weapon.

Within the neutrophil division, she functions as a junior colleague to U-1196, combating pathogens and infections alongside fellow neutrophils. She maintains a close working relationship with U-8787, frequently appearing alongside this colleague during missions.

U-1212 participates in critical defense operations, such as responding to a bacterial invasion following reproductive system activity in Episode 3. During this event, she joins other white blood cells in confronting infiltrating Neisseria Gonorrhoeae bacteria.
