First and foremost Banyou is someone who served as a close aid to Ou family for a long time and was entrusted with military education of it's hair. Y
None of Banyou’s feats make him on par with a general. Being an aid to the Ou family or having raised Ouhon doesn’t equate to that in this context. Banyou is of course also not the only one who taught or contributed to Ouhon’s abilities.
You really think Ousen would give such a responsiblility to some rando who is not even on the level of a regular general?
Not necessarily, the same applies to Kozen who was also never a general.
The method doesn't matter, the fact is, Akakin can stall an opponent of this caliber thus he can also stall Goba who is inferior to Bananji.
No since these two feats aren't the same.
My point is that the conditions of this battle are just not favorable enough for Ouhon.
From his pov there’s at least two or three entities he has to worry about, even if we exclude Tork (Rozo, Goba and Bunen) while vice versa the Quanrong only have to worry about one entity which is Ouhon.
Akakin and Kanjou as commanders are definitely handleable for the Quanrong, even in relative numbers. Bunen took out Katari, someone who I would rank higher than either Akakin or Kanjou and we’ve already gone on about Goba.
Combine that with the fact that neither Akakin or Kanjou has had much experience with leading large scale armies since they were recently promoted.
This is the argument I’m making, not that Ouhon is incapable of defeating any of the Quanrong commanders individually but that it’s too challenging for him to do so in these conditions due to limited resources, i.e. the lack of vassals capable enough to withstand the already hardened Quanrong generals.
