Insomni is a beautiful Yo-kai that makes people stay up all night. Then, the next day, they are so tired that they can’t stay awake. They also get dark circles under their eyes. Sometimes it’s fun to stay awake all night long, and Insomni feels this way too. But if you eventually decide you want to sleep, she will make you sleep forever! What a scary Yo-kai!
Insomni inspirits others by emitting red beams from her eye. The only way to defeat her is to get this nightlife-loving Yo-kai to fall asleep! Good luck!
She also has a differently-colored version called Sandi.
