Eijiro is a muscular young man of average height and a rather impressive physique for his young age. He has red eyes pointed slightly inwards, and a small scar just above his right eye. He also has small eyebrows and pointed teeth. His hair is somewhat long, dyed a bright red, and spiked away from his head at all angles, with two more pronounced tufts spiked on either side of his forehead like little horns. Eijiro is very honest and kind-hearted, having a straightforward way of thinking.
