The beloved young lady who was exiled abroad entrusted me with an enormous bomb, so I'm thinking of putting on a grand and dirty fireworks display.

"Don't cry, Chiyo." Young lady Chizuru, who is being exiled from the country, shows concern for the maid she must leave behind. When Chiyo weeps in frustration over Chizuru's banishment on false charges, Chizuru makes a request of her. A stone that purifies a distorted nation. She asks Chiyo to use it only after she herself has fled beyond the reach of the country's pursuers. Chiyo accepts Chizuru's wish, and in exchange, makes one request of her own: "Once I have fulfilled my duty, may I come after you, Miss?" This is the story of a girl left behind by her exiled mistress, who fulfills the role entrusted to her and returns to her mistress's side.
