An exceptionally clever Maricha who suddenly gained human-level intelligence after seeing Oniisan. Unlike other Yukkuri, she does not make optimistic assumptions and sees the world much like a human does. Her treasure is a turntable, and she uses a drone and a spear connected to electrodes as weapons. Unlike other Yukkuri who only use hiragana, she uses kanji naturally in her speech. Since Oniisan blasted away the Yukkuri who stole her nest, she wants to repay the favor someday. She ends sentences with '-je,' '-nanoje,' or '-daje.'
