Kim Kaphwan and Jhun Hoon vs Guy and Maki Genryusai
Bushin Ninjitsu vs Taekwondo.
Kim Kaphwan is disappointed to find out that the Bushin Ninja Guy, one-third of the original Heroes of Metro City, has become the underworld boss of Japantown.
After seeking Ryu out on the matter (the Ansatsuken master was currently in the horse stance, holding a eight-foot tree trunk over his head while Chun Li occasionally smacked his legs with a bamboo cane, as part of his training), Ryu telling Kim that despite it all, Guy remains to be one of his best friends.
Deciding that the Bushin ninja needs a lesson in justice (via opening a can of Korean Wup-Ass), Kim along with his sons and Jhun Hoon, head for Metro City.
Inside Guy's rebuilt home, the Bushin Ninja himself has a guest: his sister-in-law and head of the Bushin Dojo in Japan, Maki Genryusai when one of his Genin appear, saying that Kaphwan and Hoon are waiting for him at his dojo.
Donning his red-and-white Bushin uniform (with Maki wearing a similar uniform), Guy confronts the two Korean martial artists and Kim's kids.
Guy explains that he became the boss of Japantown as a means of keeping his side of town peaceful and free of drugs. Kim or Jhun won't hear any of it.
