Description
U-1196, designated Leucocyte 1196, operates as a neutrophil within an ailing human body suffering from poor maintenance and harsh conditions. She possesses white hair reaching mid-back length, fair skin, and an athletic yet well-endowed physique. Her standard uniform includes a White Blood Cell cap, a loose coat-like garment worn without an undershirt, white pants, sneakers, and fingerless MMA gloves, often torn in combat. A vest housing her L-selectin and radar functions rests at her lower back. She wields a katana as her primary weapon, reflecting kendo proficiency honed during her myelocyte stage in the bone marrow.

Mission-focused and stoic, U-1196 never complains about the abusive work environment or poor treatment. She remains calm and caring toward other cells, though prone to self-criticism and overwork, embodying a "heroic elder sister" type dedicated to her duties. Following transfusion into a new, even unhealthier body, she swiftly earns the trust of local neutrophils through fearless action and an unwavering work ethic, rising to a leadership position. Fellow neutrophil J-1178 initially perceives her as cold and unsympathetic toward the overworked cells but later recognizes her proactive efforts against dire threats, eventually viewing U-1196 as a mentor and partner, respectfully calling her "big sister." U-1196 consistently arrives first at crisis scenes, motivating neutrophils to persist in fighting.

Her neutrophil capabilities encompass phagocytosis for analyzing foreign cells through ingestion, receptor-based pathogen detection, free movement as a wandering cell, and transmigration through blood vessel walls for rapid response. Combat effectiveness is amplified by her katana expertise. U-1196 forms key relationships: a close friendship with erythrocyte AA2153, whom she frequently rescues and encourages. She provides physical comfort during AA2153's emotional breakdown after his friend AC1677's death; their interactions feature mutual blushing and emotional vulnerability, hinting at a deeper connection. She also shares camaraderie with two unnamed neutrophil soldiers and strengthens her partnership with J-1178 post-transfusion.

When the original body deteriorates irreparably, U-1196 is transferred via blood transfusion into a new host body plagued by worse health issues. She adapts to these intensified challenges, maintaining her determined approach to protection. Across both bodies, U-1196 consistently demonstrates crisis leadership, reinforces fellow cells' resolve, and upholds her duty commitment despite relentless adversity.
