In the city of Ert'Aria lives the young inventor Leicester Maycraft. He is part of a small adventuring clan called Oasis led by Carina Verritti, the daughter of the Archduke who rules over the city. Later that evening there is to be a regular meteor shower that comes once every seven years, and the clan is preparing a party. They meet a young puppeteer named Agnes Boulange who makes an impressive show of her magical automata puppets in the square. They also meet a young knight named Chelsea Arcot and the sisters Ritos and Salsa who run the Tortilla shop in front of their clan hall.
