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

Nientum – Op.ZERO MOD APK is a 2D rhythm-action adventure set in a forgotten theater, where Aleph and Liora wake backstage without their memories. Aleph takes the director’s chair while Liora takes the stage, and Liora’s voice is needed to raise the curtain again.

Each stage treats the theater as part of the game’s structure: you move through backstage areas, then step into live performances under the spotlight. The story follows the two girls through a theater where its lights, music, and applause have remained frozen in darkness.

Rhythm, platforming, and story

Nientum – Op.ZERO MOD APK combines rhythm gameplay, platforming, and story progression in the same stage flow. Backstage platforming leads into performance sequences, so moving through the theater and keeping time are connected rather than separate activities.

Boss encounters appear at key story turning points as rhythm duets. You win these duets by following the timing, while your choices influence how the final curtain falls.

Voice and text options

The game includes a full Japanese dub featuring Chika Anzai, Yuki Takada, and Takehito Koyasu. Text is available in five languages.

Chapters and access

You can begin with the opening chapters for free, then use a single unlock to access the full theater. Chapters 6–10 were added on October 14, 2026, opening the theater’s full chapter set.

Release background

Nientum – Op.ZERO MOD APK first released on PC in Early Access. It received Excellence in Audio at BIC 2024 and was selected for TGS 2026 SELECTED INDIE 80.

What this build changes

This build is labeled Menu, God Mode, Unlocked.

This build fits players looking for a story-led rhythm game that combines platforming with timed boss duets. It also suits players who want to start through the free opening chapters before deciding on the full theater. Pass on it if your device cannot meet the Android 7.0 minimum requirement or cannot accommodate a 2056.1 MB download. The current release notes list minor bug fixes rather than a new gameplay change.

Inside this build

This version is labeled Menu, God Mode, Unlocked. That label identifies the modification attached to this build. The underlying game remains Nientum – Op.ZERO MOD APK, with its backstage platforming, live performances, rhythm duets, Japanese voice cast, and chapter-based access structure. The listed version is 1.0.9, and its release notes mention minor bug fixes.

Strengths

• Backstage platforming flows into stage performances, giving movement and rhythm a connected role across each area.
• Boss duets appear at story turning points, making timing part of the narrative progression rather than a separate challenge.
• Choices affect the final curtain, giving the story an outcome tied to the player’s decisions.
• Japanese dubbing and text in five languages support the game’s theater-focused presentation for different readers.

Trade-offs

• The 2056.1 MB file size requires substantial storage space before you can install the build.
• Android 7.0 is the minimum operating-system requirement for installation.
• The latest notes only mention minor bug fixes, so they do not indicate a new chapter or mechanic.

Bottom line

Install it if the mix of rhythm duets, platforming, and a branching theater story matches what you want to play. Check that your device has Android 7.0 or later and enough available storage for the 2056.1 MB file first.
