this is GoDoongDoong World.
On Rhythm Island, Melody Island, and Harmony Island, unique sounds resonate from every corner. Between these islands, vibrant musical energy flows endlessly across staff bridges.
All these islands connect as one to create a magnificent symphony.
But secretly... a shadow is beginning to loom over this perfect harmony.

Since Maroong is neither a line, a space, a note, nor a rest on the musical staff, he has zero presence on sheet music—leaving him perpetually full of resentment.

Falling for the deception, Maroong teams up with the Demon King to take the lead in destroying GoDoongDoong World.

However, because she cannot produce a melody independently, she harbors a deep insecurity—feeling unappreciated and completely ignored by those around her.
That is when the Great Demon King approached her.
He tempted her with a grand promise: help him destroy GoDoongDoong World, usher in an era of pure noise, and she would finally become the true star of the show.
Blinded by this deception, Yodrey ultimately turns her back on her home and takes the lead in tearing apart GoDoongDoong World.
Having spent his childhood starved of appreciation, the Demon King harbors a deep emotional void, fueling an intense craving for validation and recognition.
Consequently, he suffers from severe mood swings—yet he will instantly flip into a sweet, gentle demeanor the second he receives a warm compliment.
While he ironically detests hearing nothing but raw noise, watching people purely immerse themselves in and enjoy music fills the Noise Demon King with bitter envy. This deep-seated jealousy drives his thirst for revenge against all music lovers.
Ultimately, he resolves to conquer his envy by transforming all the world's Musical Islands into Noise Monsters and collecting them for himself.
