When questioned by the detectives, Reimi says, "I just did it because I liked it." However, the detectives are suspicious of her words and attitude, and begin to stake out Reimi. One morning, the detectives find a video cassette in a garbage bag that Reimi had thrown away, and take it home. The video shows the various experiments Ryuji performed on Reimi, as well as a certain truth. Meanwhile, Kodama Hikaru, one of Ryuji's experimental subjects, has gone so far as to give herself enemas in private. As she was subjected to the experiments, she had truly fallen in love with Ryuji. She also goes to the police station to be interrogated and begins to talk of the events that happened between her and Ryuji. The feelings towards Ryuji hidden in each of their hearts and bodies gradually become clear.
