Itou is a character from the anime Papuwa, depicted as a small, pink, hermaphroditic snail. A notable feature of Itou's appearance is a pink bow, and it is characteristically depicted with its tongue hanging out of its mouth. Background details regarding Itou's origins or how it came to inhabit the island setting are not provided in the available information.

The personality and defining motivation of Itou are centered on a strong and persistent obsession with another character, Toshizou. This fixation drives much of Itou's behavior and interactions. A key aspect of Itou's role in the story is a biological trait: it constantly spawns or produces babies. These offspring are frequently consumed by other characters, a recurring element of the narrative. Itou's primary relationships are defined by its obsession with Toshizou, though the exact nature of Toshizou's response to this attention is not detailed. The character's interactions with others also involve the recurring cycle of producing babies that are then eaten by the surrounding cast. There is no information available about any developmental arc or changes Itou undergoes over the course of the series. The notable ability attributed to Itou is its hermaphroditic reproduction, allowing it to continuously spawn offspring, even if those offspring are almost immediately eaten.
