Megalobox

Years after his victory at Megalonia, a radically different Joe drifts from one underground ring to another, fighting under the name Nomad.

When Joe's motorcycle is stolen by a boy named Mio, he ends up at a settlement for immigrants and runs into Chief again.

Joe helps Chief prepare to fight in the upcoming Megalobox tournament; if Chief wins, he'll be able to buy the property and protect his community.

Chief reaches the last match of the tournament, and must fight against Crazy Mamiya. The spectators create a strange atmosphere inside the venue.

Joe returns to the gym he once called home, and first visits Abuhachi's shop. He discovers the area suffered a serious storm a year before.

Sachio ends up injuring a Megalo-boxer after they caused trouble at Bonjiri's shop; in retaliation, the Megalo-boxer comes back, trashes the place, and steals the deed to the shop.
