I seem to always gravitate toward the "odd man out" in a show, and for this one, I've made no exception. Cho Hakkai is neither ordinary, nor especially gorgeous (like, say, Gojyo or Sanzo). But he is a fascinating study in ferocious, bottomless rage contained (for the most part) in a smiling shell. Many of my favorite characters share this basic makeup, actually.
