Shachi

Shachi (シャチ) is a resident of Shura. When he was fifteen, he was reluctantly abandoned by his father, Akashachi, after an unsuccessful invasion of the island continent. Through the sheer willpower to live, he was able to defend himself against the ruthless residents and fell in love with a woman named Leah. Shachi once dreamed of leaving the island, but he stayed to protect her. She encouraged him to learn the values of virtue, leading him to seek tutelage under the local Hokuto teacher, Jyukei. Armed with the the fearsome techniques of the style, he protects Leah and is feared as the demon "Rasetsu".

When he learns of Kenshiro's existence on the island, Shachi plans on using the fighter to defeat the rival forces on Shura. By doing so, Shachi believes he can reign supreme and provide the grandiose protection he thinks Leah needs. He thinks Kenshiro is nothing but a pawn until he learns that Hyo is Kenshiro's biological brother. Shachi feels that protecting family ties is more precious than life, risking his life to save Kenshiro on more than one occasion. He prevents the brothers from fighting from one another throughout the story, and he is the one to reveal the truth to Kenshiro.

After Hyo recovers his memories, Shachi and Leah swears to protect the temple housing the secret technique of the Hokuto ancestors. Kaioh ambushes them and Shachi exerts himself to guard Leah and the secret technique. Though he fights bravely, he is mortally wounded by Kaioh. Shachi's courage revives the spirits of the noble Hokuto founders, and the ghosts' enmity frightens Kaioh away from the temple. Proud to have saved those precious to him, Shachi succumbs to his injuries soon after.

Fighting Style
Hokuto Ryuseiken is a centuries old assassination technique that was devised during the Three Kingdoms era. It was originally made to protect Liu Bei, whereas the Hokuto Shinken once protected Cao Cao. Throughout the centuries, the martial art was led astray into the arts of darkness. The users of the art can distort their fighting aura to oppress their competition, even capable of manipulating their opponent's movements. Non-fighters feel helpless against it, unable to move or even breathe against it. If needed the aura can be projected to form a nigh impenetrable barrier around the fighter to defy his opponent's attacks.
