Nientum – Op.ZERO v1.0.9 MOD APK (Menu)

Nientum – Op.ZERO Mod APK is a 2D rhythm-action adventure where you move through a forgotten theater, perform on stage, and keep time through key battles. Aleph wakes backstage without her memories and takes the director's chair, while Liora must use her voice to raise the curtain again.

Each stage treats music, action, and story as parts of the same performance. Your choices shape how the final curtain falls.

A theater without memories

The story begins after a theater has been left silent, with its lights, music, and applause frozen in darkness. You follow Aleph and Liora as they wake backstage with no memories and try to bring the theater back to life.

Rhythm on and off stage

Backstage platforming leads into live performances under the spotlight. The rhythm elements are tied to the story, so major turning points become boss duets that you win by staying on beat.

Japanese voices and text languages

Nientum – Op.ZERO Mod APK includes a full Japanese dub featuring Chika Anzai, Yuki Takada, and Takehito Koyasu. Text is available in five languages.

Chapters and access

You can start with the opening chapters for free, then use a single unlock to access the full theater. The game first released on PC in Early Access, received Excellence in Audio at BIC 2024, and was selected for TGS 2026 SELECTED INDIE 80.

Chapters 6–10 were added on October 14, 2026, opening the theater in full.

About this MOD

Menu, God Mode, Unlocked.

Nientum – Op.ZERO Mod APK fits players who want a story-led rhythm game with platforming between performances and boss encounters built as duets. It is less suitable if you only want a conventional platformer, because the story and timed music sections are part of the same structure. The listed update only mentions Minor Bug Fixes, so it is useful for players looking for the existing chapter content rather than a newly described feature set.

The MOD in practice

This build is labeled Menu, God Mode, Unlocked. That label sits alongside the game’s theater story, platforming sections, live performances, and rhythm duets. The official game structure still centers on Aleph, Liora, and choices that affect the final curtain.

What works

• Backstage platforming flows into spotlight performances, giving movement sections a direct connection to the rhythm stages.
• Boss battles appear as timed duets at story turning points, making major encounters part of the narrative.
• Choices affect how the final curtain falls, which gives the theater story an outcome beyond individual stages.
• The full Japanese dub and five text languages give players multiple ways to follow the dialogue.

What to watch

• At 2056.1 MB, the download needs substantial free storage before installation can begin.
• Nientum – Op.ZERO Mod APK requires Android 7.0 or later, so older devices cannot meet the minimum installation requirement.
• Minor Bug Fixes gives little detail for comparing this version with another build.

Our take

Install it if the mix of platforming, staged rhythm play, and story-driven boss duets is what you want. Check that your device runs Android 7.0 or later and has enough space for the 2056.1 MB file first.
