I really don't give a shit about Riboku
The dude lost every battle in the manga where he had number advantage every time and the god of war Hokun on his side.
Everyone's talking about Riboku when it's actually the crown prince's reaction that's more important. Unlike Sei, this guy doesn't even have the will to fight against his younger brother. So much for the hope of Zhao.
I don't like Ribuku, but I wont deny that he wasn't the worst strategist. He had many grand battles and he always managed to escape death, that alone is a great feat. So I feel a lil sad for him. A lil.
At this point, Riboku is already in his late 60s or early 70s, during his prime and before King Tou Jou become Zhao's king. Riboku is the true rival of Hakuki.
