Summary
Celena Butterfly, the thirty-third Queen of Mewni, foresaw the end of magic and the destruction of the Butterfly Kingdom. Yet her visions also showed a Prince who, under the right circumstances, could save them both.
Three Queens later, Moon unexpectedly delivers twins: a girl named Star and a boy named Sky.
Fulfilling Queen Celena’s final orders, the Magical High Commission kidnaps the three-day-old Prince and smuggles him to Earth. Now known as Marco Diaz, the Prince balances learning to control his magic alongside normal human experience, like going to school, learning karate and perfecting his super awesome nachos recipe. Along the way, he befriends two boys whose lives have also been touched by magic: his smart and curious classmate Dipper Pines, who’s determined to finish his Uncle Ford’s creature journals and Wirt Walter, his introverted neighbour who once outwitted the Beast of the Unknown.
Together, they will save magic, uncover royal family secrets and fall in love with monsters.
