It Wasn't A Ghost Knowing Eiji killed their mother, the twins aim to find his motive. While Migi is studying, Dali reprises his role as the female student Sali to approach Eiji. Dali blackmails Eiji into giving him childhood photos. In one photo from December 24, 1982, a five-year-old Eiji is shown wearing pajamas with snowflake buttons, and in a photo from the following day, there is a photo of him with the button missing. Eiji tells Dali he does not remember what happened to the button. Migi finds the dolphin pendant he gave to Sali and believes she has returned. Upon finding Dali with Eiji, Dali tells Migi that she is now dating Eiji, leaving Migi heartbroken. At the Ichijo home, Dali uses regressive hypnosis on Eiji to reveal how and why he killed their mother. Following advice Migi received that he ought to fight for the one he loves, Migi climbs to the second story of the Ichijo house where Dali (dressed as Sali) has Eiji in a hypnotic state. Eiji pushes Migi out the window, but Dali saves him from falling. Migi begins to realize something and bites his hand before falling to the ground. Still in a hypnotic state, Eiji finally remembers what happened the night Metry died. He describes how Metry came to him through the window and tried to tell him something, but Eiji became scared and pushed her away. Falling from the window, Metry grabbed the snowflake button. Eiji brought his mother to the window to show her what happened, but by then Metry's body was gone (Metry left and soon died and then Migi and Dali found her), so his mother told him it was a ghost, which he came to believe. Returning to the Sonoyama home after learning the truth from Eiji, Dali hopes to tell Migi this so they can plot their revenge. Upon returning home, Migi grabs Dali's hand to see the bitemark. Migi becomes angry at Dali for having deceived him about Sali.
