Migi & Dali

A wealthy couple adopts an orphan boy, unaware that he has brought his twin brother with him. The boys quickly scheme to win over their new parents.

Suspecting that their adoptive parents are hiding something, Migi and Dali begin searching the house and make a series of surprising discoveries.

Migi and Dali decide to join the Boy Scouts, hoping that making friends can help them get closer to finding the truth about their mother.

The twins hope to get close to Eiji Ichijo at school so they can enter his house, but they must earn higher grades to join him in the advanced class.

The Sonoyamas are invited to the Ichijo residence, giving Dali the perfect chance to explore the house — until Eiji confronts Migi about the button.

Migi decides to play the part of a perfect child in a bid to uncover the Ichijos' secrets, but the twins have little time left to explore the house.

Disguised as Sali, Dali attempts to get close to Eiji on his own. Meanwhile, Migi finds the dolphin pendant he gave Sali and begins searching for her.

A distraught Migi stays at Akiyama's house and refuses to return home despite Dali's pleas. Dali resolves to avenge their mother by himself.

Migi visits Eiji's home dressed as Sali. Eiji opens up about his and Reiko's secret and says Hitori is in danger — but Reiko suddenly appears.

After being framed for the killing, Migi and Dali seek help from Akiyama, who recruits Maruta. Together, they form a plan to take down the Ichijos.
