Frontier Works has announced a delayed release date for Heroic Songs: the Remix, the upcoming idol x city-building simulation game. Originally scheduled for September 15, the title will now launch on October 8, 2025 on Steam, with the Nintendo Switch digital release still set for November 27, 2025. The delay was cited as a move to improve the quality of the release.
Opening Movie and Theme Song
To accompany the update, Frontier Works shared the game’s opening movie on its official YouTube channel. The theme song “Follow the Glow” is performed by protagonist Akari Sunohara (VA: Seika Hirose) with lyrics by sunny and composition by Tsūten. The video was produced by En and Ayato of Miu:Z.
New Gameplay Details
While the initial announcement already described resource collection, town building, and idol performances, the new update provides a deeper look at mechanics. The game will include side stories that explore the five main idols beyond the main story of Akari’s growth.
- Players can design their Fanctuary using over 50 building types across categories like housing, production, processing, and recreation, with additional visual styles unlocked through fantasy, sci-fi, Japanese, and modern themes.
- Idol stages can be built and customized. Idols performing on them not only take part in concerts and tours but also provide boosts to nearby facilities. Their abilities can be enhanced further using skill points.
- Concerts are defined as short 30-second rhythm challenges that drive story progression, rewards, and idol experience. Some idols will unlock alternate stage outfits as players advance.
The story begins when the player and Akari are transported to the Void after a concert by top idol Ruri Tsukuyomi. Guided by Moku-san the flower fairy, they must build a Fanctuary to restore resonance between worlds. Idols are portrayed as key to rebuilding hope, and Akari’s growth becomes key to the journey.
The main characters include:
- Akari Sunohara (CV: Seika Hirose), an ordinary girl with the rare potential to become an idol bridging worlds.
- Ruri Tsukuyomi (CV: Yukimi Hayase), the “ultimate idol” whose influence echoes across realms.
- Lynalelle Singulant (CV: Hitomi Sekine), a fantasy-world idol who is also a king and idol enthusiast.
- Haru (CV: Yuka Amemiya), a veteran idol from a sci-fi world with hidden struggles.
- Kaguya (CV: Risae Matsuda), an idol from a Japanese-inspired realm and Akari’s formidable rival.
Additional supporting roles include Moku-san (CV: Masato Kokubun), Kroschel (CV: Kosuke Nakazawa), D.D. (CV: Asahi Fujino), and Charlotte (CV: Saya Shirahase).
The game is developed by Emma Create Co., Ltd., whose motto is “Continuously Create Fun.” Character designs are drawn by illustrator Rose, known for work featuring “kemomimi” (animal ear) characters
