Original otter character drawn by Uchida Shuu as a concept character for Kancolle Arcade (see post #3442956). Name literally means "I'm Otter" (as Uchida herself wrote on her illustration). The paper otter was later made into a real life mascot for the 2019 KanColle Zuiun and Reppu Paradise Festival at the Yokusuka Seaside Paradise Amusement Park.
