Student and Master Tenza recalls his early life as a street urchin when he was taken in as a student by the master Yamada Asaemon Shion who recognized his potential. Tenza and Nurugai continue their circuit of the island, but are interrupted by an androgenous Tensen which easily casts Tenza aside. Tenza uses his speed to slice at the Tensen, severing its head, but it regenerates itself and pursues them. They are saved momentarily by the blind but experienced Shion who again decapitates the Tensen. He explains that he killed the criminal Akaginu when she tried to seduce him, but then he could not find a current to lead him off the island. Suddenly, the Tensen strikes again, striking Shion in the throat and when Tenza attacks with his sword, he receives a fatal blow. In a last desperate effort to save Shion and Nurugai, Tenza attacks the Tensen with his bare hands giving his life so that they can escape.
