The curtain fell long ago on a forgotten theater. The lights, the music, the applause — all of it stands frozen in the dark. Backstage, two girls wake without their memories — Aleph, who takes the director's chair, and Liora, who takes the stage. Only her voice can raise the curtain again.
Nientum - Op.ZERO is a 2D rhythm-action adventure where every stage is a performance. Backstage platforming flows into live performance in the spotlight, and at every turning point of the story, boss battles unfold as duets you win by keeping time. Rhythm becomes the script, and your choices decide how the final curtain falls.
Voice is half of this theater: a full Japanese dub by Chika Anzai, Yuki Takada, and Takehito Koyasu.
Game Features
- A rhythm game where music, platforming, and story become one stage
- Boss duets fought in rhythm at the story's turning points
- Text in five languages
- Start free — the opening chapters are free, with a single unlock for the full theater
First released on PC in Early Access. Excellence in Audio at BIC 2024. Selected for TGS 2026 SELECTED INDIE 80.
And on October 14, 2026 — with Chapters 6–10 added — the theater finally opens in full.

2.) Download the MOD APK.
3.) Install the downloaded MOD APK.
4.) Enjoy.
Regarding login methods, please note that logging in with Google will not be possible when using signed MODs. Facebook login (if available) is possible, but it requires you to remove the Facebook application from your device. Other game-specific login methods (if available), such as email, transfer code or guest login usually work fine.
Notes:
- If you used our MOD APK before and just want to update, you can install the new MOD APK on top of the old without removing the game/app first.
- In-App purchases are not possible on signed APKs as they require Google services similar to the Google login process.

Unsigned APKs do only work on rooted and patched devices/environments.
These are not always provided by the mod publisher as they do only work under certain circumstances.
1.) Your device must be rooted.
2.) Your device must be patched to ignore app signatures. This can be done with the help of tools such as Luckypatcher or Xposed.
Once you fill that requirements the process is the same as with signed APKs with the difference that you can overwrite the original game/app with the MOD APK without removing it first.
1.) Download the unsigned MOD APK.
2.) Install the unsigned MOD APK.
3.) Enjoy.
Note:
For the case the unsigned APK does fail to install: Your device patch is not done correctly!
Login methods and In-App purchases on unsigned MODs function the same as in the original game. Logging in with Google works without issues. Keeping the Facebook application installed is also no problem.
