Shu

Shu is "plucky," daring and doesn't think before he acts. He usually will run right into a problem on his own, without thinking or talking to anyone about it. He has a special relationship with Kluke that he isn't willing to admit out loud. Shu has the Blue Dragon shadow, whom Jiro and Zola were looking for at the beginning, because of its unspeakable power. Near the beginning, he doesn't seem very bright but as the story moves on, many can see how strong his willpower is.

Shu is practically obsessed with knight masters and that's what led him to find Jiro and Zola, whom he thought was a true knight master. Along his journey with Kluke, Jiro and Zola by his side, he has met the perverted, yet all-for-justice Marumaro (with the Saber Tooth Tiger shadow) and Bouquet (with the unable-to-fight Hippopotamos shadow), his "bride-to-be".
