Sherbert is a magical creature from another realm called Lylasia, where different species of magical creatures are locked in a Magical Beast War. Immature and infinitely curious, Sherbert accidentally triggers a portal and ends up in our world. Without any knowledge about our world and our ways, he vows to become a hero here...and battles other magical creatures who make their way across the rift.
