Nientum – Op.ZERO Mod is a 2D rhythm-action adventure that combines music, platforming, and story inside a forgotten theater. You follow Aleph and Liora, two girls who awaken backstage without their memories, as Liora's voice becomes the way to raise the curtain again.
Each stage is presented as a performance. You move through backstage platforming sections before stepping into the spotlight, where timing and rhythm drive the action and the story moves toward its final curtain.
A Theater Without Memories
The theater has been silent for a long time: its lights, music, and applause remain frozen in the dark. Aleph takes the director's chair while Liora takes the stage, and their missing memories frame the journey through the theater. The story places decisions at key turning points, so your choices affect how the final curtain falls.
Rhythm, Platforming, and Performances
Nientum – Op.ZERO Mod treats rhythm as part of the action rather than a separate activity. Backstage platforming leads into live performances, creating a structure where exploration and musical timing share the same stage. The game is built around the connection between its music, movement, and narrative scenes.
- Move through backstage platforming sections before entering the theater's live performances.
- Keep time during rhythm-focused sequences as the story progresses through each stage.
- Make choices at important story moments that influence the ending.
Boss Duets at Story Turning Points
Major confrontations take the form of boss duets. These battles occur at turning points in the story and are won by maintaining rhythm, turning musical timing into the central part of each encounter.
Japanese Voice Cast and Text Languages
Voice is a central part of the theater setting, with a full Japanese dub featuring Chika Anzai, Yuki Takada, and Takehito Koyasu. Text is available in five languages, giving players multiple reading options while following Aleph and Liora's story.
Opening Chapters and Full Theater
You can begin with the opening chapters for free, then use a single unlock to access the full theater. Chapters 6 through 10 complete the theater's opening, extending the game through its later chapters.

Mod Review
This build suits players who want a story-led rhythm game where platforming leads into live performances and boss duets. It also fits readers interested in a Japanese voice cast and a theater setting built around Aleph and Liora's missing memories.
