Jingi 33: Gokudo Revenge War(仁義３３ 極道復讐戦争)

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.

What is the true meaning of Takechi's appearance over 12 years ?!
