A manga artist named Art Stanley requests that Yuma and Shark be models for his manga, but Shark refuses. Unknown to them, Art is under the Barians' control, tailoring Shark to report his weakness to Girag. The next day, Shark discovers that Rio has gone missing and is confronted by Art, who challenges him to a duel. Art quickly summons his Xyz monster, Comics Hero King Arthur, and uses Rio as a means to stop Shark from fighting back, claiming she will become trapped forever if he is defeated. Believing Art's sketchbook may provide a hint to his weakness, Yuma and Ray set off in search for it. Meanwhile, Art forces Shark to summon out Shark Drake and deals a lot of damage before activating Barian's Force, ranking up King Arthur into the Chaos Xyz monster, Comics Hero Legend Arthur, using it to destroy Shark Drake. After some encouragement from Yuma, Sharks calls out to Rio and manages to both free her from captivity and awaken her. Shark soon regains his resolve and brings out Shark Drake Veiss to win the duel. (thetvdb.com)
