About the Game

"—To fade away... was it hope for you and me, or despair?"

『Nientum – Op.Zero』 is a 2D action-adventure music game that combines platformer, action, and adventure elements.

Tune the stage through musical interactions and experience a unique journey to breathe life back into a theater that has settled in a gray stillness.

A Strange Play Created Without Memories

A theater once filled with songs and stories is now filled only with silence.

In this desolate place, Aleph and Liora, who have lost their memories, become the Director and the Actress to raise the curtain on a new play.

On a stage that is beautiful yet foreboding, warm yet sorrowful, they discover lost clues one by one.

What truth will they face in the final scene of this play?

Prepare the Stage Through Action — The Power of 'Tuning'

The gems scattered throughout the stages are fragments of broken notes.

Use Aleph’s ability to tune them, play their restored notes, and restore stage devices to complete the preparations for the performance.

As platforming, puzzles, and action naturally intertwine, the theater begins to regain its vitality.

The Performance Unfolds on the Stage You Tuned

The Wizard of Oz, Cinderella, The Legend of King Arthur...

Familiar tales are reinterpreted, and sometimes twisted, into musicals that unfold before your eyes.

With each of Liora’s successful performances, a fresh glow of life returns to the theater. And their journey continues to the next act.

Truth Brought to Light — Endings Shaped by Your Choices

Nightmares and hope, wishes and despair, new encounters and farewells.

The fragments of memory lost by Aleph and Liora are revealed one by one, following your choices.

Depending on the direction of your choices, the end of the story takes a completely different turn, drastically altering their fates.

Please, join them in their journey and help raise the curtain on this strange play.

Music and Voices that Bring the Stage to Life

The stage is filled with music composed by renowned artists such as
Kagetora., Halv, and seatrus, delivering a deeply immersive experience.

The main characters—including Aleph and Liora—are brought to life by talented voice actors such as
Chika Anzai, Yuuki Takada, and Takehito Koyasu, vividly expressing the beauty and strangeness of the theater.

Additional Content

  • Director's Room: A space where you can record and view the various collectibles gathered while completing the play.
