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. Said platelet has later gained similar meme status to Kanna Kamui from Kobayashi-san chi no Maidragon, as both were popular loli characters and voiced by Naganawa Maria.
