Bubble

After a mysterious phenomenon causes bubbles to rain down and shatter the laws of gravity, Tokyo is severed from the rest of the world. The abandoned metropolis transforms into a sprawling playground for orphaned youths who now settle their disputes through intense parkour team battles, leaping fearlessly between ruined skyscrapers. Among them is Hibiki, a gifted young ace notorious for his dangerously reckless style of play. During one such match, Hibiki pushes his limits too far and plunges into the treacherous, gravity-distorting sea below. He is rescued by Uta, an enigmatic girl possessing extraordinary powers. Immediately following her intervention, the two begin hearing a strange, unique sound that only they can perceive. Their sudden connection raises profound questions about why Uta appeared at that exact moment to save him. As the pair are drawn closer together, their fateful encounter sets in motion a revelation destined to change the world forever.
