Once regaining his human form, Gou was shocked at how much had changed and that Retsu was practising Geki Jūken. Though he is of the Geki Jūken, Gou lacks a passion for justice and fights only for himself. This resulted in Gou developing and mastering a dangerous form of Geki, called , and reinventing the Wolf-Ken as his personal , a form that uses Muay Thai fighting moves. Xia Fu believed that Gou actually does have a passion for justice, and commissioned the Gong Changer for Gou to use. After much soul searching and cajoling by the others, he agrees to become Geki Violet and overcomes the beast within him thanks to Bae. Using his Shigeki, Gou can summon Geki Tiger and Geki Jaguar and control Geki Tohja Wolf on his own. Gou desires to defeat Rio and prove himself as his rival, holding some animosity towards Jyan in this regard, but accepts that he is not up to the task after mastering the strongest Geki Waza but still failing to defeat Rio. He is later glad when Rio joins the fight against Long.
