In the Meridian Empire, DiDi TiTi receives a letter that sends both hope and frustration through her veins. It contains three words, ones that make DiDi drop all the tasks she is in progress of in order to find the answer herself. "He is here." An important person in her life has gone missing for six years and this is the only chance she has to find them. Seeing that the Meridian Empire is temporarily not in need of DiDi's presence, she leaves all of it behind her as she travels great distances to the city of Dalia- a place where all of her answers will be unlocked.
