The Kingdom of Haricot stands out as a complete mystery as 20 years before the event of the story, it inexplicably took to the skies, turning into a series of disconnected floating islands, allowing the power-hungry Church of Aloe to take hold of the land.

Entering Haricot by sneaking on one of the Church’s aircrafts, Vernal has a personal disdain for the Church and its agents. She is an independant adventurer, travelling through Haricot as she searches for revenge on her long-gone deadbeat dad. Blessed with an abnormal martial prowess and helped by the amnesiac automaton Chervil, she goes through the different islands of the Kingdom with her own aircraft.
