Shigure

Mokuren Shigure was a major antagonist in the manga/anime series, Demon's Quest. He was a member of the Earthbound Royals, and a great friend of Taishin Tarou. Shigure is something of a "Mutant", being created through experiments of Demon apparition, and Human DNA. As a result, he was created and designed as a warrior, bent on proving himself as the world's strongest Elementalist. Shigure's travels of mass murder and body counts eventually led him to Tarou, who he was utterly humiliated by. Swearing to one day kill Tarou, or die trying, Shigure tagged along with Tarou. Shigure swore to never lose to anyone before facing Tarou once again, or else he'd take his own life. Shigure also had an intense rivalry with Jun, who he desired to kill as well.

Personality
Shigure's defining trait, as stated by Tarou, is that he is completely stoic and is void of all emotions. Shigure's creation is the reason behind his initial lack of emotion beyond determination, hatred, and disgust. Shigure is an extremely confident individual, who takes great pride in his abilities. He was designed to fight to the top. Shigure's non nonsense attitude and calm demeanor usually makes him out to be the most composed of Tarou's group of friends. Of all of the Earthbound Royals, Shigure is shown to have a closer relationship towards Jun, who he develops a level of respect for due to the challenge of a fight that Jun is able to consistently bring to him, and he has a soft spot for Oyuki, who as the only human in the group, gets some flak from Jun, but Shigure takes her human antics and curiousity as a sign of development and admires Oyuki's desire to learn more about herself. Tarou may be the only person Shigure actually regards as a friend, due to only having respect for the other Earthbound Royals. Shigure's goal to kill Tarou has developed into eternal respect, due to Tarou giving him the chance to rematch him. For this reason, Shigure had sweared an oath to take his own life if he cannot defeat anyone before fighting Tarou once more.
