Every 15 years a new Queen is selected to reign the hidden village of Dundansae. Keeping their myths and secrets, this village of trained ninjas has long closed its door to the outside world.
But not for long.
Lota, a teenage boy who dreams to see the city, joins the selection for the next Queen by pretending to be a girl. To his luck, he is crowned Princess and proclaimed as the next heir to the throne.
Everything is going as planned until he is forced to steal the ring only meant for the rightful Queen.
And accidentally wears it.
With no memory of what happened, Lota wakes up at the doorstep of a cupcake store located at the heart of Paris.
