Megalobox

Junk Dog is a talented underground Megalo Boxer forced to throw illegal matches for his boss, Gansaku Nanbu. Megalo Box enhances traditional boxing with mechanical equipment called Gear, but Junk Dog's skill cannot take him far while his fights remain controlled by others.

Everything changes when champion Yuuri enters his ring and defeats him in a single round, then challenges him to earn a legitimate rematch. Junk Dog takes the name Joe and enters Megalonia, a global tournament designed to determine the strongest Megalo Boxer. Starting from the bottom of the rankings with only three months to qualify, he must fight opponents unlike any he has faced before.
