It is grandmother Haruko's birthday. She wants everyone home early for her special day: the day that serves as a reminder that she has been alive for more years than she can remember. Unfortunately, her family has completely forgotten and make up last-minute birthday promises to Haruko. The game begins like any other normal day for the family members - father Taneo, mother Etsuko, daughter Ririka, and son Tsuyoshi - until strings of events stand as obstacles in their way of returning to Haruko's with the presents.
