Bangoro, the son of the judo instructor Shibukawa Hanryuken, saves Jinpachi and his daughter from Kurosaki Tenzen, who is holding them under a false pretext around the precincts of the Kanon Temple in Asakusa. He also punishes Sengo Tayu who has beaten Yotsuguruma in a sumo wrestling match by using a forbidden technique. However, Tenzen spreads false rumors about Bangoro, who is expelled by his judo school for abusing his fighting strength. One day, after Bangoro arbitrates a quarrel between two sumo wrestlers of the second highest rank, he is ordered by the Lord of Arima to kill an enormous spider. Where does this lead Bangoro?
