Hataraku-saibou hikaye

Illustrated Story! RBCs are generally afraid of WBCs, especially of neutrophils, due to their role as killers. But after seeing 1146 & AE 3803 get together, 4989 figures things don't have to be that way and wishes to change the way none-immune cells perceive them. Starting with an erythrocyte he's recently saved does seem like a good idea, unfortunately she too fears WBCs. Of course that is no reason to give up, it just requires making an effort.

In the human body even daily work can be life-threatening. Faced with dangerous incidents once again, among them Malaria, caused by a red blood cell destroying parasite, both AE 3803 and U-1146 finally begin to grasp something about their relationship. The other neutrophils, U-4989 especially, have noticed this too and are eager to help them along...preferably without the two noticing them meddling.
