In hindsight perhaps there was a reason why Kochou was only introduced as a "General" and not as a "Great General".
Kochou is like the opposite of Choutou.
Choutou was an old, patriotic bad arse that actually died on his own terms while shredding dozens of fools and wrecking named characters (including the little bitch that poisoned him to begin with) all while hemorrhaging enough blood to paint the side of a house.
Kochou is an old guy that seemingly hates the Zhao royalty but serves them anyway, who got strategically lol diffed, cut his own neck in a rather limited attempt to "die on his own terms" and killed less than a half dozen blokes and nobody important.
