Acchi lives in the attic above a restaurant where he works as a cook. His main focus is food preparation, and he shows constant enthusiasm for both cooking and eating diverse dishes. As one of three supernatural beings, Acchi joins his companions in playful antics, causing lighthearted mischief in the neighborhood. Their activities sometimes involve surprising humans by vanishing suddenly or floating through the air. Unlike traditional frightening ghosts, Acchi and his companions are defined by their mischievously playful, childlike nature.
