History
In the anime, Insomni appeared and caused trouble for Nate's class after having kept them from sleeping the night before, causing them to start becoming ill from lack of sleep. She actually threatened to make Nate "sleep forever" for interfering with her. Nate summoned Baku to take her on. After their attacks collided, Insomni and Baku had a faceoff in a wrestling arena in which Insomni is eventually the winner. However, it turns out it was all in her head, as she had passed out the instant she was hit by Baku's sleeping gas. In her stupor, she conceded her medal to Nate.

In Yo-kai Watch, Insomni operates the elevator to the Yo-kai World.
