Sumo of BOOM‪!‬

Sumo of BOOM! is a New Earth tournament involving eight men attempting to overcome unreal odds and ends to be crowned champion of a sumo tournament. New Earth is sort of like earth, but not really. It is a single elimination tournament that is based around the cultural concept of sumo wrestling, but that is at most a springboard for alternate reality. The ring is surrounded by nuclear ash, and the competitors are eight men.
