Zenzou's Father was once a highly skilled ninja and member of the Oniwabanshuu when he was young. He died two days before a funeral was held by Zenzou and all of his students. They recounted his deeds of using kick-the-can as part of ninja training, just as his ghost returned to have one match with Kagura.
He acted as a double for the Shogun and prevented an attack from Jiraia, which would have made history take another course. During his battle with Jiraia, Zenzou's Father got his legs jacked, and legs are what make a ninja, but also mentioned that he may have also simply get tired of dirty business and moved on to train next generation of ninjas, as explained by Zenzou in Episode 179.
He was said to be one of the most formidable warriors within the Oniwabanshuu, and that as a teacher at Ninja School, he brought up all of the renowned ninjas in Edo of today.
