What it is about

Chiikawa and friends set off on a whimsical summer adventure to a mysterious island said to hide a long-lost mermaid secret. What starts as a fun getaway quickly turns into a heartwarming journey filled with surprises, gentle thrills, and adorable chaos. With sparkling seas, strange legends, and unforgettable encounters, the trio learns about courage, friendship, and the magic hidden in small moments.

What to expect

Chiikawa and friends wash up on a mysterious island in this 99-minute feature, the first cinema outing for the manga and anime series. The Japanese voice cast returns, and the Hong Kong release keeps the original language with English and Chinese subtitles. The story moves between low-key discovery and gentle sentiment, never rushing its small-scale gags or the quiet reflections tucked between them. It carries a Category I certificate, so there is nothing to worry about for younger viewers. This is a special Siren Vehicle screening, playing at 19 cinemas across 14 districts with 341 showings in the next week. Tickets start at HK$60.
