Bubble

Five years after gravity-warping bubbles with unknown properties poured over Earth, an unexplained blast left Tokyo sealed inside an enormous sphere. The former capital sank into a distorted, gravity-bending sea, prompting the government to designate it a forbidden zone and driving its residents to abandon the city.

Now, orphans of the “Bubble Fall” slip back into the ruins, living as squatters and throwing themselves into perilous parkour team battles across crumbling skyscrapers. Hibiki, a standout among them with a knack for leaping from bubble to bubble, insists he can hear a strange sound calling from Tokyo Tower. When his search leads to a fall into the waters below, he’s rescued by an enigmatic girl he comes to call Uta—an encounter that begins to draw out the truth behind the catastrophe that reshaped their world.
