An exceptionally smart Maricha who suddenly gained human-level intelligence after seeing an 'Oni-san' (Abuser). Unlike other Yukkuri, she does not make optimistic predictions and sees the world much like a human does. Her treasure is a turntable, and she carries a spear connected to electrodes and a drone as weapons. While other Yukkuri use only hiragana, she naturally uses kanji in her speech. Since an Oni-san blasted away the Yukkuri living in her stolen nest, she wants to repay the favor someday. She ends her sentences with '-je,' '-nanoje,' or '-daje.' She generally doesn't care about her peers but cannot ignore a Yukkuri in trouble or pain. She never commits harmful acts that trouble humans.
