Hokuto no Ken EP73 - Ryuga of Sirius! I'll Seize the Rainbow in Tempest!!

Ryuga visits the graves of Shin and Yuria. Meanwhile, Ken-Oh returns to reclaim his territory in which some of his former lieutenants have become even more brutal than he was. One group has the misfortune of encountering Kenshiro, who stops them from mistreating the townspeople. Kenshiro then meets Ryuga, a martial artist and servant of Ken-Oh, whose astrological sign of the solitary star Sirius is neither part of Hokuto nor Nanto. Ryuga punishes the former troops and reclaims the territory for Ken-Oh. When Ken-Oh returns to claim his throne, Ryuga requests permission to challenge Kenshiro.
