[21] In 1983, a young Migi and Dali are seen standing on a bluff above Origon Village while holding a snowflake button, with an unmarked grave positioned behind them.

In 1990, 13-year-old twins, Migi and Dali, acting under their alias as one person named Hitori, used their room as base of operations to investigate the people of Origon Village.

While the couple is out planning for Hitori's welcoming party, the twins, searching around the house, find a shelf full of colored wigs laden with a particular odor, which they interpret as the Sonoyamas hiding something.

They later find a metal object in the garden shed, which believe is a machine that will scalp their son to use his hair to make a wig.

During the welcome party, they meet neighbors including Mrs. Ichijo and her children Eiji and Karen, Mrs. Tsutsumi and her grandson Maruta, and Shunpei Akiyama.

Migi and Dali's earliest memories were of them living with their mother hiding in a room with paisley wallpaper (that they describe as water fleas).

In December 1982, they are now living in a tent rather than that hidden room, though their mother still speaks fondly of her love for Origon Village.

Migi is locked in a hidden room where Eiji asks him how he obtained a button from his pajamas that was lost to him eight years ago.

As the Halloween costume contest commences, Eiji presents as sad and listless such that Dali convinces everyone that he is dressed as a beggar and his intense lack of expression shows how dedicated he is to staying in character.

Migi learns from Eiji that he stepped in to protect Hitori because he feels a need to atone for the sin of having pushed a woman out of his window to her death.

Eiji tackles his mother to allow Migi to escape, but Reiko grabs his hair, pulling off the wig to reveal him.

The four enact their plan with Akiyama dressing in his bird costume to distract the police who are searching for Hitori allowing Maruta and the twins to access the Ichijo house through Karen's bedroom window.

Dali fears that he will fall to his death as the tree branch supporting the rope begins to break, but Migi saves him.

Reiko, who had been feigning pregnancy, takes away the middle triplet with black hair and names Eiji as her own child.

In her bedroom, Reiko is dead and Eiji lies next to her, reminiscing about all the "perfect" times they all had together but laments that the blonde women he had accidentally killed had been his birth mother.

Due to the scar on Dali's face from the fire, he is no longer able to switch with Migi to play the role of Hitori.
