The film is based on the “Mermaid Island Arc,” which garnered significant attention during its serialization on social media in 2023. The story follows Chiikawa and friends, Hachi and Usagi, as they receive an invitation to a “special island” promising hundredfold rewards and exclusive gourmet treats in exchange for simple tasks. Lured by the offer, they set sail for the island alongside the cautious sea otter, Usaki. However, what seems like a paradise soon reveals hidden dangers, including mysterious mermaids and unexpected events, setting the stage for an adventure beyond their wildest imaginations.

Key Visual Hints at Mysterious Plot Twists
The key visual released alongside the announcement offers tantalizing clues about the story.

Lurking beneath the water’s surface is the faint silhouette of a mysterious creature, foreshadowing suspenseful twists in this seemingly idyllic journey.

Since its serialization began in 2020, Chiikawa has captivated audiences worldwide with its blend of adorable art style and subtly dark, realistic themes.
