Description
**AE3803:** This red blood cell transports oxygen, carbon dioxide, and nutrients. She possesses bright red hair with an ahoge, amber-brown eyes, and a reversible jacket signaling gas transport status (bright red for oxygen, dark for carbon dioxide). Her uniform features a beret shaped like a red blood cell. Her origin lies in the bone marrow, where her red hair led to selection as a red blood cell. As an erythroblast, peers teased her for clumsiness and disorientation. During training, she strayed into a restricted zone, attacked by a Pseudomonas aeruginosa bacterium. A young myelocyte (implied as U-1146) intervened, though both faced defeat until a neutrophil resolved the threat. They parted promising reunion, but neither recalled this as adult cells. Post-enucleation, she became a full erythrocyte yet persisted in navigation struggles, often relying on guidance from senpai AA5100 or U-1146. She matured into a mentor for rookie NT4201, emphasizing hands-on learning and eventually gaining recognition for reliability. AE3803 exhibits chronic disorientation, frequent apologies, and a cheerful, helpful nature. Despite clumsiness, she shows determination in crises like hemorrhagic shock or hypothermia, persevering with oxygen delivery despite exhaustion. She shares a close, teasing relationship with U-1146, who often rescues her from pathogens, and acts as a nurturing figure to platelets. Her "AE" designation references hemoglobin E trait, a mild anemia explaining reduced gas-transport efficiency and airheadedness.
**AA2153 (CODE BLACK):** This red blood cell operates in an unhealthy body. He has brown hair, glasses, and wears the same uniform as AE3803. Initially enthusiastic as a rookie, disillusionment set in due to the body's deterioration (e.g., smoking, alcoholism). His close bond with fellow erythrocyte AC1677 ended tragically when AC1677 died during a stomach ulcer incident, triggering AA2153's emotional breakdown. He briefly rebelled, attempting to damage the body during a gout attack, but later reconciled with his role after U-1196's encouragement. Transferred via blood transfusion to a second, worse body, he faced mockery from local erythrocytes but persisted in advocating for improvement. He formed alliances with neutrophils U-1196 and J-1178 (whom he nicknamed "White Blood Cell-chan"), evolving into a determined leader motivating others despite escalating threats like diabetes and depression. His resilience involved overworking to compensate for the body's decline, though peers reminded him survival required collective effort.
**Shared Traits:** Neither AE3803 nor AA2153 possesses combat abilities, as their functions are purely transport-based. However, both demonstrate exceptional endurance and strength from carrying heavy loads and navigating tight spaces.
