Naoya joins a group of friends camping in the woods. A sudden rainstorm drives them into an old mansion for shelter. He displays an arrogant and confrontational attitude, especially when reacting to Jun's panic over signs of recent occupancy. Inside the kitchen, Naoya physically knocks Jun down and orders him silent. Later, both are captured by the mansion's mysterious female resident. She strips them nude and chains them to a white room's walls. As she toys with them, Naoya attempts flirtation. He negotiates for his release by suggesting she remove Jun and the restraints so he can "please her properly." When the woman mentions he could be with the female members of their group instead, Naoya becomes boastful and aggressive. He expresses a violent desire to assault their friend Seiya, explicitly vowing to "ravage her body" and "put Seiya in her place." This provokes the woman's anger. She stabs him in the heart with a knife, killing him. His friends later discover his body in an empty mansion room.
