Bubble

In a near‑future Tokyo the very laws of physics have turned fickle, as countless invisible bubbles warp gravity into a constantly shifting puzzle. The skyline is a maze of floating fragments, towers become unreachable monoliths, and the streets pulse with a disorienting sense of weightlessness. Survival has become a performance, with daring parkour squads turning the city’s erratic terrain into a kinetic arena where every leap can be both a means of trade and a statement of defiance. The atmosphere hums with a blend of neon melancholy and restless energy, hinting that the city itself is alive with secrets waiting to be uncovered.

Hibiki is an 18‑year‑old prodigy whose agility on rooftops makes the impossible look routine. Beneath his confident flips lies a quiet isolation, sharpened by an acute sensitivity to sound that forces him to navigate the world with a heightened internal rhythm. He moves through the fractured metropolis with a blend of precision and yearning, constantly drawn toward the faint, haunting melody that seems to rise from the very bubbles surrounding him. His skill earns him a place among the most respected parkour crews, yet his solitary focus leaves him searching for something more than physical mastery.

Uta appears as a mysterious figure who seems to have been born from the very air that distorts the city. She moves with an instinctive grace that mirrors Hibiki’s own style, and the song in his mind feels strangely familiar when she is near. Their connection forms amid the ever‑shifting streets, hinting at a deeper bond tied to the strange gravity that plagues Tokyo. Together they navigate a world where every jump and every whispered note may hold clues to the phenomenon itself, setting the stage for a story that balances breathtaking visual spectacle with an intimate, almost lyrical exploration of what it means to find humanity in a world that no longer obeys its own rules.
