Quent Yaiden is the secondary antagonist of Wolf's Rain and an ex-sheriff from the town of Kyrios. His hometown was destroyed, seemingly by wolves, and his wife and son, Russe, died in the process. This led to an intense hatred for wolves and an obsession for hunting down every wolf he could find (as well as a constant desire to drink). He travels around with his dog Blue, who aids him in wolf hunting, and an ever-present rifle.
Quent is first seen ranting to a bartender about the devilish nature of wolves. Soon after, he sees Toboe alone in Freeze City and attempts to shoot him, but Tsume attacks him and saves Toboe's life. From then on he drifts from city to city, tracking down Toboe and his pack throughout the series.
Even after Blue discovers that she is part wolf and runs away, Quent goes on without her for several episodes. He meets her again in Jaguara's city while she is in human form. He refuses to believe her when she reveals the truth to him--that the ruin of his home and his life was not caused by wolves, but by soldiers, and declares that she is not his dog anymore.
The destruction of Jaguara's city leaves him injured and he and Blue are eventually picked up by Hubb and Cher. After having his life saved by Cheza's power, he wakes to find Cher, Hubb, Blue and the wolves all around him and, refusing to be with wolves, goes off on his own. Toboe follows him. Darcia appears before them and raises a gun. Quent fires his own gun in defense but accidentally fatally wounds Toboe, who leapt in front of him to block Darcia's gun.
Quent allows Toboe to lie on his arm before he dies, and acknowledges Blue as his dog once again before his own death.
