The Asian small-clawed otter "fairy baby" character debuted on December 15, 2017. The "eternally 0-year-old" character has no gender, and they wear the turtle character Kame-chan on their head.

The mascot character is based on a real-world female pet otter of the same name, who gained a social media following big enough to become the honorary tourism ambassador of the city of Susaki, Kochi.
