Zeus (ゼウス Zeusu ) and Aus (アウス Ausu )
- The two sons of Koryu, with Zeus being the eldest of the two. Despite being the sons of a former Hokuto Shinken practitioner, the two brothers never learned the style, since their father was forbidden from teaching it after conceding succession to Ryūken.
- After Raoh kills their father, the two brothers confront him inside the cave and attack him with steel rods which bend upon impact. Raoh strangles the pair of them and warns them that if they are true brothers to take separate paths or face the same fate. He then relinquishes his grip and spares their lives.
- In the anime, Zeus and Aus attempt to kill Raoh while he's leaving the cave by crushing him with an avalanche. Raoh emerges from the rubble unscathed and the rest of the scene follows its manga counterpart.
