Hanatare-kun is a character from the anime Pururun! Shizuku-chan. He is a nasal-mucus sprite who resides in Shizuku Forest, the primary setting of the series. His existence is part of a group of bodily fluid-themed sprites, which includes other characters such as Hanaji-kun, a nosebleed sprite, and Yodare-kun, a slobber sprite. This group's design and thematic role fit within the series' surreal comedic approach, where everyday elements are anthropomorphized.

In terms of background, Hanatare-kun emerges in the early episodes of the original Pururun! Shizuku-chan anime. His first appearance is specifically in Season 1, Episode 3, which is titled "Hanaji-kun to Hanatare-kun." This episode pairs him directly with Hanaji-kun, reinforcing his thematic link to nasal motifs. Throughout the series, his characterization remains consistent as a nasal-mucus sprite, and he is established as a minor supporting character among the larger community of Shizuku Forest's inhabitants.
