The facility called Rikitake was not a place one entered willingly. It was a terminus for the broken, the brilliant, and the damned. Buried three hundred meters beneath the artificial island of Nami-no-Kuni, its corridors were lined with lead and silence. Suzune Wakakusa knew this because she had counted every step of her descent.

"Correct." The warden slid a tray through a slot in her cell door. On it: a single origami crane, folded from silver leaf, and a vial of clear liquid. "Your daily choice. The crane or the draught."

Because Suzune Wakakusa, Entry No. 012, had never been the patient.

Whir. Click. Unfold.

She had chosen the crane for 411 days. Each one she unfolded, studied the crease pattern, and refolded into a different shape—a wolf, a lotus, a spiral that collapsed into a point. It was a test. Rikitake was an experimental facility, and every inmate was both prisoner and puzzle. The cranes contained encoded data. The draught was amnesia.

"To the birth of a new Thought-Whale. Not in the ocean. In the psyche of every human connected to the global net. A cacophonic birth." She closed her eyes. "I'm not the anomaly, Warden. I'm the alarm bell you've been locking away."

She was the cure.

Instead, Suzune pressed her palm against the cold floor. The concrete was embedded with piezoelectric filaments—designed to dampen psychic resonance. But Suzune had spent 411 days learning its harmonic flaws.

Her crime? She had listened to the Song Below.

The Song Below was not music. It was a frequency emitted by the Earth's molten core—a resonant thought-pattern older than humanity. Most brains filtered it out as noise. But Suzune’s unique neurology, the very gift that had made her a prodigy, turned noise into meaning. And what she heard had driven three of her assistants to suicide and one to claw out his own eyes.

"I'm sorry," Suzune said, and she meant it. "But you've been containing the wrong thing."

"The Song Below has changed," she said, loud enough for the hidden microphones. "It's no longer a dirge. It's a countdown."

The lock on her door snapped open.
