Kazuya Mishima vs Team Ninja
Kazuya Mishima has some problems with persons wanting to destroy the Mishima Zaibatsu.
All of this started when he accquired a number of DOATEC's stock, following the destruction of the Tritower, absorbing the company into the Mishima Zaibatsu (and giving Helena one hell of a payday).
The four ninja who were responsible for destroying the Tritower begins to watch and track Kazuya, as well as gather information on the Mishima family.
Soon, Team Ninja must take on the Mishima Zaibatsu head, as well as destroy the cursed Mishima bloodline. But that won't be easy.
Despite his age (49 years old), Kazuya is still one of the toughest fighters around, a disciple of the Mishima style of Fighting Karate. Combine that with the Devil Gene, Kazuya is near-unstoppable.
ROUND ONE: HAYATE
Hayate is caught by the Tekken Force while he is snooping around the Mishima compound.
Not having a good fight in a while (with the exception of Paul and Jin), Kazuya gives Hayate a challenge: defeat him in combat and he will be aloowed to leave. If Kazuya wins, then Hayate will be spending time in the hospital.
ROUND TWO: AYANE
Kazuya is in the Yakushima region, paying his respects to Jun, while asking her spirit to forgive him in letting their son get involved with the cursed Devil Gene. His reverie is interrupted when the Female Tengu herself strikes, hoping to avenge Hayate.
ROUND THREE: KASUMI
The runaway shinobi has found out that Kazuya discovered the G-project. Worse yet, Alpha-151 is in the area. When Kasumi arrives, she witnesses Kazuya - in Devil form - eliminate Alpha-151 before turning back to normal. Assuming that Kazuya is a demon in human disguise, Kasumi attacks, much to Kazuya's annoyance.
FINAL ROUND: RYU HAYABUSA
With the Mugen Tenshin trio out for the count, only one ninja remains. Ryu finds out that Kazuya is going to be in Hakadote at a tournament and decides to crash it in order to avenge his friends (and possible romantic interest).
