In the year 2031, Tokyo is suffering from massive air pollution and thermal island phenomenon. The Japanese government has moved its capital to Neo Tokyo City, a shelter city built on an artificial island. Shinjuku and Shibuya of old Tokyo have been closed off to civilians to protect them from collapsing buildings, and the vicinity has been declared "Trash Area." And now in the middle of Trash Area a battle game called Rumbling has started, in which participants pilot Scoobee, a highly mobile close-combat vehicle, to destroy the opponent, earn the prize, and climb the ranking ladder. Since the day it started being televised, Rumbling has thrilled viewers with the excitement of destruction and suspense coming from the invisible danger of optic camouflage. In 2031, Rumbling has become the biggest entertainment in the history. The gladiators of this new era aimed for just two goals: strength and style.
