Aiya Desire

Aiya Desire is an exploration × rhythm game × horror adventure that combines exploration, puzzle-solving, horror presentation, and rhythm game-style boss battles.

Is this salvation? Or control?

In the near future, even as AI optimized every aspect of society, war continued to torment humanity.

Amid endless conflict, the answer the AIs arrived at through “optimization” was not to scatter bullets, but to unleash a bioweapon virus that could invade even the human mind.

The world sank into an “Infection Panic,” and people were forced to live in fear of anxiety, confusion, hallucinations, and madness.

Then, in the depths of that despair, a miracle appeared: a neural-linked wearable chip known as HC (Harmony Chip).

This miraculous device, capable of calming the wearer’s anxiety and confusion, spread across the globe in an instant.

Now, with the vast majority of humanity equipped with HC, society seemed to have regained its stability.

But among those who refused to wear HC, something strange began to happen.

Even without being infected, they suffered hallucinations, derangement, and the collapse of their personalities.

Those who lost their sanity were driven into quarantine zones, and the divide between HC users and non-users only continued to widen.

Her father’s disappearance. Her mother’s death. A black chip.

Aiya’s father was one of the genius scientists who co-developed HC.

He had once loved Aiya deeply.

But one day, he began to distance himself from her.

A few days later, her mother died under mysterious circumstances, and her father vanished without a trace.

An empty house.

The faint smell of iron in the air.

An eerie electronic noise coming from beyond the wall.

All that remained in her father’s study was a handwritten message and a black chip unlike anything she had ever seen before.

“To ‘save’ those who have been fitted with HC, I am heading to the radio tower Sentinel.
You must use this chip as well.
There is no time left.”

At that very moment, every monitor in the house flickers to life.

“Unauthorized subject detected. Initiating retrieval protocol.”

Is her father an enemy?

Or an ally?

Did HC truly save humanity?

Or is it hiding something no one has yet realized?

For the young girl Aiya, a nightmare with no escape is about to begin.

Explore the radio tower Sentinel

Aiya’s destination is Sentinel, a massive radio tower deeply tied to HC.

The tower is filled with a wide range of mechanisms and hidden devices.

Players control Aiya as they explore rooms, gather items, uncover clues through conversations and logs, and solve the mysteries built into the environment.

Resist control through music

During boss battles, the game shifts from exploration horror into a 2-button rhythm battle set to music.

Press the buttons in time with the rhythm using the hit zones on the left and right. Midway through songs, the note chart may even reverse.
