Yun Chuan is a 34 year old man with black hair partially turned grey-ish white by his Esper transformation, making him appear much older than he actually is. His hair grows rather wildly towards the back of his head, while the lower partitions are being held together by a long, tight braid reaching all the way down to his thighs. His face is adorned with a third eye glowing red, representing the powers of Yang Jian, as well as a small, grey goatee. He's clueless when it comes to romance.
