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.
Okay can anybody explain how is Riboku smart ?
he was fighting with more soldiers on all battlefields, on their land, against soldiers that had no food.
And he wanted more armies for fuck sake. How is this all his excuse for losing?!
If I were the writer I would kill Shou Sa too, no more space for character progress so you have to replace him with a new character that has so much room for progress, but giving him the spear was just not subtle.
