dont remember who but some body was asking why this was called shura no toki the side story .. well the original (Shura no mon) comes from and old 31 volume series that was published in Koudansha's Monthly Shounen Magazine from 1987 until 1997 the hero in this one is Mutsu Tsukumo..

so far we seen only two of his special moves

Mukuuha "no air wave", or "vacuum wave" Mutsu creates a miniature vacuum by causing his fist to vibrate at an extremely high rate, and he releases the energy as a wave into his opponents body. Capable of breaking ribs and doing damage to internal organs.

Ikazura "Thunder" A vicious throw manuever, Mutsu breaks his opponent's arm over his shoulder, performs a hip throw, and kicks his opponent in the back of the head on the way down.

there'r others dont want to spoil so I'll just tell you the names

Kohou "Tiger Cannon" , Gazan "Fang" , Shishikou "Lion's Roar" , Jahazan "Snake Wave" , "Ryuuha "Dragon Wave" , And the last one my favorite Shimon "Four Gates" or "Gate of Death" <------ I always wanted to see the animated one hehehe
