Successor of the "Nanto Koshū Ken" (South Dipper Lone Eagle Fist) style. One of the Nanto Rokusei Ken, Shin's star was "Jun-sei" (Martyr's star). Shin grew up as a good friend of Kenshirō's, but secretly loved Ken's betrothed, Yulia . Jagi realized this and used this to turn Shin against Kenshirō, persuading him to turn to evil and to take Yulia before someone else would. Shin did so, defeating Kenshirō and putting the seven scars on Ken's chest in the shape of the Hokuto Shichisei. Shin called himself King, raised an army and built a city called "Southern Cross". But Shin could not make Yulia love him. When Shin learned that Raoh was approaching Southern Cross, Shin knew he couldn't keep Yulia safe and he entrusted her to the Nanto Goshasei. Kenshirō fought Shin believing that Shin still had Yuria, punching the symbol of the Southern Cross in his chest. Shin told Ken that Yulia had died, and he jumped off the building before Ken's attack could take his life.
