The first smartphone app for the anime "Chiikawa," titled "Chiikawa Pocket," will host a "Mermaid Island" event starting July 24, 2026, featuring new costumes and a login bonus.
From July 24 to August 28, 2026, the "Mermaid Island" event in "Chiikawa Pocket" will let players explore the world of the film "Chiikawa: The Secret of Mermaid Island." Players can earn rewards including 5,000 "Small Candy" through event missions, obtain a "Welcome to the Island Flag" featuring Hito and Futa, and face the enemy "Siren" in challenge battles. A special login bonus on the second day will grant the "Mermaid Island" costume for Hachiware.
Additionally, a campaign called "Chiipoke Chase Challenge" runs from July 17 to July 23, 2026, on the official X account, offering serial codes for 10 "Mysterious Branches" to successful participants and a lottery for 50 winners to receive a "Chiipoke Clear Poster." A countdown campaign from July 17 to July 23 will provide daily ad skips and a special gacha with increased rates for "★7 Help" items. The app will also air commercials at select TOHO Cinemas and Aeon Cinemas starting July 24.
AniHeat's take: Worth noting for fans of "Chiikawa" who enjoy in-game events tied to the film, as this offers exclusive costumes and rewards like the Mermaid Island Hachiware outfit.
