EPISODE CONTEXT

As the first of only three episodes, 'Phone' carries significant weight as both world-builder and hook, establishing Kagami Village's unsettling atmosphere, the sisters' fractured relationship, and the supernatural mystery that drives the entire series. Nothing precedes it, but the episode's cryptic revelations and deliberate ambiguity are clearly engineered to escalate through the remaining two installments. Every detail introduced here — the village folklore, Sui's absence, the warning call — functions as groundwork for the suspense and identity-driven narrative ahead.
