EPISODE CONTEXT

As the thirteenth and final episode, 'Warmth on the Sea Floor' follows directly from the emotional revelations of Episode 12, 'Beloved Child,' functioning as a reflective epilogue rather than a traditional climax. The full season built toward understanding the supernatural tensions and emotional entanglements between Hinako, Shiori, and Miko, and this finale serves as the exhale — exploring what healing and a new normal look like for these characters. It closes the series with deliberate open-endedness, offering thematic resolution while leaving the door open for interpretation.
