Jingi 33: Gokudo Revenge War

The Kanto Ichienkai was devoted to the conflict with Hokuriku. At that time, Jin and his brother Tsuda appear in front of Jin in the former sand group. Tsuda was in a position to steal the money of the Hokuriku Union and be chased. Hitoshi and Yoshiro saved Tsuda's crisis, but it was Takechi, a brother of former Sunagawa group leader Sunagawa, who followed Tsuda. Twelve years ago, Takechi boarded an enemy territory alone in order to protect the sand group, which was still a weak organization, and was banished from Kanto due to that. What is the true meaning of Takechi's appearance over 12 years ?!
