platelet_(hataraku_saibou)

A personification of various platelets featured in the manga and anime series Hataraku Saibou.

They are depicted as children wearing a long blue shirt, shorts, a yellow satchel, and a baseball cap with the word 血小板 (Platelet). They are usually depicted having a whistle and holding a yellow flag with the word for "No Entry", depicting the role of platelets for covering an open wound of a human.

While there are large numbers of platelets featured in the series, the one that stands out from the others and became a favorite character of the series is the one with long brown hair and brown eyes that was blocking the road in chapter 1, later revealed to be their leader.
