01 / THE GUIDE

Linear Storytelling

Harmonia presents its narrative without any decision points, so the plot proceeds exactly as written, similar to watching an anime or reading a novel. This design ensures every player experiences the same sequence of events.

Because there are no branches, players can focus on the story’s emotional beats, voice performances, and musical accompaniment without worrying about alternate outcomes.

  • Enjoy the story at your own pace; there’s no pressure to replay for different endings.
  • Take notes on moments that resonate, as they will be the same for all players.

02 / THE GUIDE

High‑Definition Visuals

The game runs in full HD (1920×1080) delivering crisp character art and backgrounds. This resolution lets the colorful graphics and animations appear sharp on modern displays.

Combined with the voice cast, the visual fidelity enhances immersion, making each scene feel like a moving illustration.

  • Set your monitor to native 1080p for the clearest image.
  • Adjust brightness to highlight the vibrant color palette.

Multilingual Text Options

Players may switch the in‑game text among English, Japanese, or Simplified Chinese at any time. This includes menus, options, and the digital manual, while audio remains Japanese‑only.

The ability to change language on the fly helps non‑Japanese speakers follow the story without restarting.

  • Switch languages before starting to avoid missing subtitles.
  • Use the digital manual in your preferred language for clearer instructions.
