Nyuru Nyuru!! Kakusen-kun

Nyuruo is a young pore-clog born in the strange little world of a human nose, and almost everything around him is new. Senior Kakusen creatures teach him about the skin, pores, oil, and the peculiar life cycle of their kind, though their explanations are rarely as dignified as a scientific lesson sounds.

Nyuruo's innocent questions turn the hidden life inside human skin into absurd comedy. Surrounded by eccentric elders and fellow pore-dwellers, he learns what it means to be a Kakusen while discovering that even something humans desperately want to remove can have a surprisingly complicated society of its own.
