Cells at Work!

This is a story that happens inside a human body. One day, as a Red Blood Cell is delivering oxygen and carbon dioxide, she is assaulted by Pneumococci and rescued by a White Blood Cell. To protect the body that’s their world, the White Blood Cell (Neutrophil) chases after the one Pneumococcus who’s escaped. But the enemy has hidden himself in the most unlikely place...

Things have been peaceful for Red Blood Cell when suddenly an abrasion occurs before her eyes. The White Blood Cells (Neutrophils) arrive to battle the bacteria and viruses invading through the wound, but they struggle against enemies like Staphylococcus aureus. Will the White Blood Cells (Neutrophils) find a way to defend this body?

Naive T Cell is patrolling the body for influenza virus proliferation. But since he’s never taken on the enemy before, he’s completely terrified and useless. He finally ends up fleeing the battlefield where White Blood Cell (Neutrophil) and the veteran Killer T Cells are fighting. Naive T Cell is filled with self-loathing until Dendritic Cell sees him and speaks to him kindly.

Bacteria appear near the stomach. White Blood Cell (Neutrophil) is on the scene at once. There, he finds Eosinophil, another type of White Blood Cell, already in battle, but she’s struggling badly. Seeing how powerless she is, the other cells start trashing Eosinophil behind her back. Even after White Blood Cell (Neutrophil) tells them, “There’s a job that only Eosinophil can do...”

The body has been invaded by a mass of cedar pollen! Rushing to the scene so that he can eliminate the cedar pollen, White Blood Cell (Neutrophil) runs into Memory Cell. Memory Cell is a Lymphocyte who retains the immune system’s memories. Seeing what’s actually going on, Memory Cell is strangely flustered. “What the heck? This is just like the legend...” What “legend” is Memory Cell talking about?

Let me become a great red blood cell one day... This is the story of Red Blood Cell before she became Red Blood Cell, when she was a young Erythroblast. The Erythroblasts are training hard to become full-fledged Red Blood Cells under the supervision of their teacher, Macrophage. But Erythroblast is directionally-challenged, and she’s always getting lost in the middle of drills. One day, while practicing to evacuate from bacteria, Erythroblast once again loses her way...

One day, while White Blood Cell (Neutrophil) is busy exterminating germs, he meets Backward Cap, a Platelet who wears her cap backwards. She is secretly training to become a stronger Platelet. However, a huge rumbling noise suddenly echoes inside of the body followed by violent shaking.

Memory Cell sees a dream where the arrival of messengers from the outside signal the end of this world... As if his dream became reality, unidentified enemies enter the body! Does Memory Cell not only have the power to remember the past, but also predict the future now? Will this world be ruined as Memory Cell predicts?

Toxic reaction found on the epidermis! Mast Cell does her job according to the manual, but complaints pour in from other cells that are annoyed by her actions. Mast Cell loses her cool and unleashes her rage... An incident occurs where an unknown entity breaks through a blood vessel and the blood cells get sucked away!

An incident has occurred in the body! The Immune Cells rush to the scene and fight the cells infected by a virus. An Ordinary Cell observes this everyday scene with a bored look on his face and says to himself, "I want to heroically save somebody and have them say to me, 'Thank you for helping me.'" A group of mysterious bacteria appear in front of the Ordinary Cell and...

Ordinary Cell heads to the intestines with White Blood Cell (Neutrophil) to reunite the lactic acid bacteria with their friends, but they get separated from one of the bacteria on the way there. Ordinary Cell desperately searches for the lactic acid bacterium but is attacked by cells infected by a new virus!

The antibody information of a cell has leaked. There is tension in the air after NK Cell makes a comment to White Blood Cell (Neutrophil). The journey to reunite the lactic acid bacteria with their friends takes the group to the large intestine. In the intestine, which has been irritated due to toxic gas being released by harmful bacteria, the group meets up with Memory T Cell who was formerly known as "Killer T Cell."
