About This Game

Build a Sanctuary for Idols Across Fantasy Worlds!

A City-Building × Idol Simulation Game

■■ About the Game ■■

Heroic Songs: the Remix! is an Idol × City-Building Simulation Game where you help develop a land known as the Void while guiding the main heroine, Akari Sunohara, on her journey to become an idol. Build roads and facilities, attract new residents, and transform this desolate world into a vibrant Fanctuary worthy of the spotlight!

● A Diverse Lineup of Buildings

With over 50 unique buildings, you'll have plenty of ways to shape your city!

- Basic Facilities such as houses to attract Fans, and roads to connect your buildings

- Production Facilities, placed around resource tiles and visited by Fans to gather materials

- Processing Facilities, which convert one type of resource into another as a result of Fan visits

- Recreational Facilities, where resources are spent to generate Likes, a key progression resource

You can also earn Likes through Tours, or the rhythm-based Concerts described below.

As you progress, you’ll unlock building styles inspired by the other worlds you visit—fantasy, sci-fi, Japanese, and modern-day aesthetics. And don’t forget to check out the diverse designs of your Fans, who arrive from across the multiverse to support their oshi! ♪

● Idol Stages

By constructing personal stages, idols will perform for their Fans by singing and dancing in town! Idols with stages become available for Concerts and Tours, and will boost the surrounding buildings whenever they’re present.

As idols gain experience from performances, their levels rise—enhancing those building effects even further! You can also assign skill points to customize how their influence spreads across your city. ;)

● Concerts

Concerts are short, 30-second rhythm games. Keep in time with the music to hit the target score and clear the stage! Successful Concerts will unlock new story content, boost idol and Fan experiences, and provide rewards. Some idols will also unlock alternate stage outfits as you progress through the game.

● A Wild Yet Heartfelt Story Unfolds!

Progress through successful concerts, construction projects, and city development to unlock new chapters in the story.

Follow Akari Sunohara—an ordinary girl with a love for idols—as she discovers her true calling. Dive deeper into each of the five main heroines in dedicated Character Stories, and experience each idol’s unique charm!

■■ Story ■■

You were just enjoying a concert by the legendary top idol Ruri Tsukuyomi… and then you woke up in a strange, unfamiliar world.

Rescued by Akari Sunohara, a cheerful girl with a deep love for idols, and guided by Moku-san, a flower spirit, you learn the shocking truth: you and Akari have fallen into a mysterious dimension called the Void, and there's no way home—at least, not yet.

Your only hope lies in Akari’s hidden potential as an idol. In this world, idols are more than performers—they’re beacons of hope and the key to restoring lost connections between realms. But Akari can’t do it alone. She needs your support.

To return home together, you’ll need to build a city in the Void—an idol sanctuary known as Fanctuary that will light the way!
