Yo is a lean but muscular young man of slightly above-average height with incredibly spiky auburn hair, left to flow wildly behind his head. He has a massive piece of stone covering his right eye. He typically wears a short, grey sleeveless yukata that leave most of his legs exposed. He has a very large shoulder pad on his left shoulder and wears a spiked necklace. Like many in Tsukasa's Empire, he goes barefoot, though he does decorate himself with ankle bracelets.
