EPISODE CONTEXT

As episode 1 of 13, this is pure foundation—establishing the central conceit of Migi and Dali's shared identity as 'Hitori' and introducing the Sonoyama couple who serve as their unwitting adoptive parents. The episode prioritizes premise over plot, ensuring viewers understand the rules of the twins' deception before the mystery of their true motivations unfolds across the season. Everything introduced here—the fragile disguise, the idyllic suburban setting, the brothers' unspoken agenda—becomes the framework for escalating tension and darker revelations in the episodes ahead.
