Zentarou Cat is a Sir'Kai from the world of Talsdia. As his last name suggests, he is a feline in appearance, standing upright at 5'10 with gray fur all over, a lighter gray 'mask' around his eyes, muzzle, and somewhat on his cheeks, and blue eyes. Typically he wears purple robes with purple boots (purple's his favorite color) and a sword on his left hip, sharpened only on one side. Over the heart on his robes is a symbol of three interlocking rings or blue (top), orange (left), and purple (right), a diagonal line, and a red ring encircling the branch of a tree. Zentarou has an identical twin brother, Zantar, with whom he shares a very tight bond.
Of the Bretheren Arcanum, Zentarouo is the weakest in magical power, as magic only recently returned to his people. In fact, he is the only Sir'Kai known at the moment to cast magic at all. He had a diginified yet gentle personality, and is very clever at breaking riddles and such. He is close to Orko, looking up to the more powerful mage and appreciating his jokes and humor, which closly match his own.
