Gintoki gets amnesia from a traffic accident, and any attempt to help him fails. The following scenes with his last words and the children tearfully asking Gintoki to help them in exchange for their treasures (read children's trinkets) is touching in a heartwrending way. Just as he sets out to escape Edo and start over, the Tendoshu (who are behind the ring) have him killed. The top fighter turns out to be a kindhearted father to orphaned children who wants to try and start a new life.

Early on in the series, Sougo asks the Yorozuya to investigate the illegal underground fighting ring.He then says that he loved Gengai as the father he knew, despite problems they had in the past, implying that Saburo's soul was in the robot Gengai created.
