Yoriichi is a tall man with a muscular build, fair skin, maroon eyes, and long spiky hair with red tips that he kept in a ponytail. He has a similar overall appearance to his twin brother Michikatsu, but unlike him, he was slightly more slender, had shorter bangs, and wavier hair than him. A calm and respectful individual who wore a solemn and reserved expression at all times, rarely showing outbreaks of emotion.
