One day, as Chiikawa and Hachiware were relaxing in the square, a rabbit with a flyer stuck to its face suddenly appeared.
When Hachiware examined the flyer, it turned out to be an invitation that read, "We invite you to a special island."
Lured by the appealing words on the flyer, Chikawa and her friends decided to go on a training camp to an island.
Chiikawa and her companions board the ship with a stingy sea otter who is suspicious of the flyer's contents, and upon landing on the island, they are warmly welcomed by the islanders.
Chikawa and the others were having a good time,
Upon hearing the fact that a giant "siren" living on the island was carrying the islanders away one after another,
I get caught up in a plan to defeat the Sirens.
Chikawa and her friends face one challenge after another as they move forward with unwavering determination. Can they overcome them all...?
And what is the real "secret" hidden on the island...?
"The movie Chiikawa: The Secret of the Mermaid Island" will be released on Friday, July 24, 2026!
