Akira Nakamura has never lost a fight. That's why he's called "The Invincible". He is the master of every martial art and fighting style. He even created his own martial art known as, "Kiai no Tenshi". He is a great teacher too, but hasn't taught anyone. He'll only teach someone who is worthy. He wants to be surpassed someday. He is 21 years old. He punches and kicks faster and harder than anyone.
