At the start, when Ouki was first introduced, I did not really think that highly of him. He looked like a future villain, who probably wouldn't last very long. Problem is, the latter was the only truth. He was a deeply inspiring man, who at some point managed to convey the true image of a Great General of The Heavens to us, the cast, and the characters.
For me, Ouki quickly became one of my favourite characters of all time, in just a span of a few dozen chapters.
RIP.
