Yo-kai Medallium biography
"When Sandi inspirits you, the two of you will play in your dreams. It's too fun to ever wake up from."
Sandi ( is a Japanese: おねむの精 ) Onemu-no-sei Rank S Drain-attribute Rare Yo-kai of the Eerie tribe.
A white skinned Yo-kai with a single turquoise eye accented by pale pink eye shadow and a stripe with a yellow iris of dark indigo. She has long dark pink hair worn in two large horns on top of her head, held by black ribbon. She wears a dark purple dress with pale pink and blue material wrapping around her torso. At the end of her tail is a pale pink flame.
Sandi's powers function as the reverse of
Insomni's abilities, where Sandi instead pulls you into a dream where you and her will have so much fun that you won't want to wake up. Sandi's grip has been known to last as long as six months.
