Ryuga

Ryuga (リュウガ) is Yuria's older biological brother and Juza's older half brother. He is born under the Sirius Star, which is considered the "lone wolf" of the heavens with its bright shine.

To test Kenshiro's worthiness as the "messiah of the end of the century", Ryuga allies himself with Raoh and becomes one of his lieutenants. He wishes to stabilize the turbulent new age they live in, but Ryuga is also keen to see if Kenshiro can reach his full potential. Committing several horrendous acts, including an assault on the heavily ailed Toki, his actions ignites the younger brother's anger in a final confrontation.

To Kenshiro's surprise, Ryuga accepts his punishment with little resistance as he had intentionally hurt himself before their fight. He reveals his true duty is to guide and test who was actually worthy to lead the new age: Kenshiro or Raoh. Accessing that the kinder younger brother is more worthy, he gladly expresses his belief in Yuria's assessment before dying from his wounds. Toki's spirit lifts his body after his death and they both become stars in the heavens.

Fighting Style
Taizan Tenrōken (泰山天狼拳 "Tai Mountain Heavenly Wolf Fist") severs flesh from its victims with fast, slicing attacks, severing their nerves so quickly that it inflicts a cold sensation before they die. Ryuga makes several wolf-like poses while performing his attacks. Unlike most of the martial artists in the series, Ryuga's fighting style belongs to neither the Hokuto or Nanto disciplines. One of Ryuga's signature techniques is Tenrō Tōga Ken (天狼凍牙拳 "Heavenly Wolf Freezing Fang Fist").
