Limited information is available about the character named Cutie from the anime Puniru is a Kawaii Slime. Cutie is a fictional mascot character within the world of the series and is not a character who appears as a living being interacting with the main cast. Instead, Cutie exists as a popular franchise of merchandise and goods, comparable to real-world character brands. Kotaro Kawaii, the young boy who created the slime Puniru, is secretly a devoted collector of Cutie-chan goods and memorabilia. He finds the mascot genuinely cute but keeps his enthusiasm a secret because he believes the character has an image that is more popular with girls. This secret affection for Cutie is a source of conflict and comedy in the series, as Puniru, who desperately wants to be acknowledged as the cutest being by Kotaro, sees the mascot character as a rival for his attention. Puniru’s desire to surpass Cutie in cuteness is a significant motivation for her actions, as she believes that if she can be cuter than this popular character, Kotaro will finally look at her again with the same wonder he did when they were younger. Therefore, Cutie serves as a standard of cuteness that Puniru strives to exceed and represents a part of Kotaro's personality that he tries to hide from his peers.
