Eosinophil is a character from Cells at Work! who helps protect the body by fighting off parasites. She often stands out for her cool and calm attitude, but also shows a shy and cute side when others praise her. Eosinophil isn’t very strong against bacteria, but she is very brave and has a strong sense of duty to protect other cells, especially against threats like parasites that others can’t handle. She has a special bond with White Blood Cell U-1146, and her unique pink outfit and twin tails represent real features of the cell she is based on. Eosinophil’s personality, abilities, and story moments make her a memorable part of the series.
Eosinophil is a young woman with long blonde twin tails.
She wears a pink jumpsuit, which represents the dye used when real cells are stained for experiments.
Her twin tails are meant to show how a real eosinophil cell’s nucleus is split.
She always carries a two-pronged spear as her weapon.
Eosinophil is usually calm and very cool in tough situations.
She is shy and gets embarrassed and flustered easily when others praise her.
She rarely smiles, but when she does, her happiness is noticeable and cute.
She is also very determined and has a strong sense of justice, fighting bravely even when she is afraid or not as strong as other cells.
If someone compliments her a lot, her face lights up with happiness.
Eosinophil is a type of white blood cell that grew up in the bone marrow, the same place as the Neutrophil.
When she was younger, as seen in episode 27, she was timid and once cried during training because of a plush bacteria toy.
She trained alongside White Blood Cell U-1146 even from her bone marrow cell days.
Eosinophil uses a two-pronged spear to fight.
She is not very strong against bacteria and is usually not trusted to handle them alone.
Her main job is to destroy parasites inside the body.
She has a special talent for fighting large parasites like Anisakis, which even White Blood Cells cannot handle well.
She can also interpret the confusing phrases of Basophil.
She is close to White Blood Cell U-1146, whom she has known since their early development.
Other cells sometimes underestimate her, but they respect her more after seeing her real fighting skills.
She gathers with other Eosinophils during special reactions, like allergy attacks.
Fighting Parasites
In episode 5, when a huge parasite called Anisakis invades the body, Eosinophil steps in to fight even though others want her to escape.
She defeats the parasite alone, proving her real strength and earning much more respect from the other cells.
Childhood Days
In episode 27, her young days as a bone marrow cell are shown.
She is frightened easily, even by a stuffed bacteria toy, and trained side-by-side with U-1146.
Allergy Reaction
In a special episode about asthma, Mast Cell throws leukotrienes at her and she gets very angry.
When more Eosinophils gather, Helper T Cell spreads her private photos (like cytokines), making her even angrier and causing a huge allergy reaction in the body.
Her jumpsuit color is chosen based on how real cells are colored in labs.
Her twin tails show that the real eosinophil cell’s nucleus is split into two parts.
Anisakis, the parasite she battles, is shown as a monster rather than as a human character, unlike most cells and bacteria in the show.
If she’s complimented too much, her happy face is quickly calmed back down by a stern expression, known as the “green demon.”
She is unique for being good at understanding Basophil’s hard-to-understand way of talking.
