Prior to the 14th tournament, Tung tells Shun'ei about KOF, the world's largest fighting tournament. Although Shun'ei is less than thrilled to hear about it (since he still isn't sure if he can fight others without his powers fatally harming them), Tung mentions that his former students, Terry Bogard and Andy Bogard, will be attending this year. Additionally, Kyo Kusanagi will be there too, which catches Shun'ei's attention. Shun'ei has heard stories about the Kusanagi heir sealing away a great evil, and wishes to meet him. As Tung's last disciple, he sets out to challenge other fighters from all over the world with his close friend Meitenkun, as Team China.
