The Wrath of Vajra

Long ago a death cult called the cult of Hades was formed at the Hades shrine in a faraway land, where children of their enemies were abducted and trained into deadly assassins to avenge their opponents and to instill fear in the minds of the people. One of these children, K-29 ( Huzi) who has the power of the '17-seconds-deadly moves' (also known as the wrath of Vajra), grows up to be an especially gifted assassin. There's no one at Hades who could defeat him, except Daisuke Kurashige whose powers were an equal match to that of K-29. However Daisuke lacked the true power of Vajra that K-29 had.
