Katsuro Yamada (克郎山田 Katsurō Yamada)is a Legal Mage that is a member of Hydra Head and is under the tutilage of Peter Reyes. He is a user of the Caster Magic, Beast Mimicry Magic and the sole user of Beast King Card Magic.


Katsuro is a tanned young teen of average height and slightly muscular build. He has short, dark blue hair that reaches down to the back of his neck. He also has bright golden eyes when mimicking, they are usually blue.

Before the timeskip he was usually found wearing his trademark white t-shirt with a shirt blue coat and black trousers. He also wears a necklace around his neck which is decorated with a single long tooth. The tooth of his first animal kill, which was a Sabertooth tiger. He also wore basic black combat boots with a rough grey sole.

After the timeskip (during which he trained with the Beast Kings) he seems to have gained a leaner more muscular body. He now wears a green yukata and goes barefoot. 

Brief History

Katsuro never knew his father properly. When he was born his mother looked after him and his father was rarely home. When he was seven years old his father returned one day and told him they were going on a trip to test his strength. So they drove off to a forest quite far from home. His father dropped him off and left him his final words. "Find your way home..." For the first few weeks Katsuro just pondered why he was in the forest and how he was going to survive. He lived of wild berries and caught animals in trap he made himself.

Determined to get home, Katsuro sought desperately to get out of the forest and in the process discovered he could do magic. He eventually got out of the forest and returned home a year and a half later only to find that no one was home. Lost, confused and alone he met a mage who took him in an raised him in the discipline of magic. It was difficult because Katsuro;' magic was unusual but eventually he was able to teach Katsuro how to generally manipulate his magical energy. Katsuro eventually left and resorted to roaming around Fiore to look for odd jobs from random strangers.

Once whilst on a stroll in the town he came across Peter Reyes and actually tried to rob him because he thought the latter was rich, his attempt failed and he was caught. Annoyed at Katsuro's waste of potential Peter took him under his wing and trained him so that he could be the best and even allowed him to join his guild Hydra Head.



Katsuro is a very calm cool and collected character most of the time. Due to him being alone on most of his travels and avoiding most people unless approached. When with his very few friends though, Katsuro is a very fun person. He loves enjoyment and never likes it when people are down. Due to his natural affinity to the forest (as he lived there for 1 and a half years) he finds it a little easier to make friends with animals than humans. Katsuo is usually a good obedient friend to those he cares about but can be very skeptic about their ideas and plans. He's also the type to take charge when no one chooses to do so.

When in a fight Katsuro is a bit of a tactician, taking advantage of his opponents obvious weaknesses and his strengths in battle. He tries to be very creative and unpredictable with his fighting style and has a reasonable amount of knowledge when it comes to fighting animals. Katsuro also likes a challenge though he is not dumb enough to go charging into a powerful enemy without reason (unlike some people).

Katsuro has a thing for animal cruelty, he hates it a lot. Not to the extent of environmentalists, but he does take it extremely seriously when habitats are destroyed of rare animals are harmed. 

Magic and Abilities

Katsuro has become so experienced with the magic that he can used Evolved Mimics of animals (which are basically when the particuler feature of the animal is evolved to release special abilities e.g. if experienced enough the user can cause a mimicked frogs jump to be able to jump in midair).  Katsuro has no official fighting style. Most of his attacks are generally freestyle strikes with some acrobatic finesse in order to keep opportunities for the opponent to strike at a minimum.

Katsuro can use up to 5 Mimics at one time and 3 Evolved Mimics at once also.

Unique Mimics
