Takeshi Takasaka, a dedicated player in a virtual reality game, regularly interacts with his 'girlfriend' character. One day, his childhood friend Reina Kagurazaka pays him a surprise visit and proposes a trip to a shrine. Takeshi declines, prompting Reina to challenge him to a video game duel. The stakes are high: if Reina wins, they will visit the shrine together, but if Takeshi emerges victorious, he can request a favor involving Reina's body. Despite his win, Takeshi never intends to exploit Reina. However, a surprising turn of events unfolds when Reina becomes curious about Takeshi's physical attributes.
