AA2153

AA2153 is one of the two protagonists of Cells at Work! BLACK. He is a rookie erythrocyte in a poorly maintained body that is subject to high stress, inadequate exercise, and imbalanced nutrition.

Appearance
This Red Blood Cell is a male with glasses and yellow pupils. He has average-length brunette hair with a strand that slightly resembles AE3803's iconic ahoge. He wears a uniform that only differs from AE3803's by the collar.

Personality
As a rookie, AA2153 was initially excited for his task of going to the lungs, only to find LDL's, Carbon Monoxide, and Pneumococcus along the way. He is dedicated to doing his part in helping the body, however is strongly disheartened by the awful work conditions and failure of the body to improve. He develops a friendship with a neutrophil, U-1196, who frequently rescues him. When the body survives a heart attack and begins to improve, AA2153's attitude becomes more optimistic and resolute.

After being transfused into a new body with even worse conditions, AA2153 is scorned and mocked by several local erythrocytes for his belief that this body can turn itself around. Despite this harsh welcome, he goes out of his way to encourage the other erythrocytes and cells to work harder for the body's sake, even as successive tragedies take away new friends and shake his outlook. During his separation from U-1196 in the immediate aftermath of the transfusion, AA2153 finds himself repeatedly saved by another neutrophil, J-1178, who he calls "White Blood Cell-chan", much to her embarrassment. Eventually, the deteriorating conditions in the second body strain even AA2153's hopes, but he continues forging ahead and eventually becomes a leader among the erythrocytes.

Trivia
