EPISODE CONTEXT

As the twelfth and final episode of the season, 'The Little Mermaid' follows the intense supernatural confrontations of the Hell of Mirrors arc, shifting toward emotional resolution rather than action-driven climax. It serves as the capstone to Nene's character development across the entire season, crystallizing her evolving relationship with Hanako and the cost of navigating a world caught between the living and the dead. While it provides meaningful thematic closure, it deliberately leaves threads open — particularly around Hanako's own mysteries — setting the stage for a potential continuation.
