Takeshi Takasaka is a boy completely absorbed in video games, even on New Year's Day. His childhood friend, the one-year-older Reina Kagurazaka, is a selfish and spoiled girl. When she invites him on a date (disguised as a New Year's visit to the shrine), he's completely unresponsive. Furious at his indifference, she challenges him to a fighting game match with an outrageous condition: "The loser must do whatever the winner wants." As expected, Reina suffers a crushing defeat... and her chastity is the forfeit.
