Nanto Jūnin Kumite (南斗十人組手,South Dipper Ten Man Tournament)
A tournament held by the Nanto school where the challenger must defeat a series of ten Nanto fighters. If challengers from another school fail to complete the trial, they are punished with death.
Raoh entered a young Kenshiro into the tournament in order to assess his potential, while Souther, the successor to Nanto Ho-oh Ken, supervised it. Shu was Kenshiro's last opponent, and managed to defeat the boy. Despite Souther's order for Kenshiro to die as a result of his loss, Shu refused, blinding himself and sacrificing his vision instead.
