Napple Tale: Arsia in Daydream is an action-adventure game for the Sega Dreamcast. Players control Poach Arsia, who is unintentionally transported to the dreamlike Napple World during a Summer Festival. Guided by the novice Spirit Guide Straynap, Poach must navigate distinct seasonal realms to reclaim six escaped fairy beings known as Petals, ensuring her return home.
While enjoying the once-per-year Summer Festival, the heroine Poach Arsia is accidentally brought to Napple World due to a mistake made by Straynap, a novice Spirit Guide who leads souls into the afterlife. Napple World, known as the land of daydreams, lies between the Real World and the Deep Dream, where souls go to rest. The concept of time in Napple World is unlike the real world: the seasons of spring, summer, autumn and winter exist separately from each other as distinct locations. When Poach arrives in Napple World, six fairy-like beings called Petals leave her body and escape into the seasons, and she must retrieve them in order to go home again. To make up for his mistake, Straynap becomes Poach's guide and instructs her throughout the game, explaining the often contradictory nature of Napple World to her.
