If you think about it in a broad sense then yeah, they are both 6GG tier so in a way on the same level. Although like I said, Karin's feat are nowhere near to consider her his exact equal. Neither does she have the hype of having 6GG level strategic ability years before becoming important figure like Ousen.
I'm not talking about in a broad sense, i'm talking about in a very narrow sense related to specifically these two. If one is 99 the other is 98.
Why would you use feats as the basis of your argument, while at the sametime acknowledging she lacks screentime. That'd just make it a bad faith argument. It's the equivalent of me trying to judge Tou right now vs Ousen, then going "Oh Tou ain't got the feats Ousen does".. like bro no shit, that mf hasn't had a proper campaign since essentially the coalition. And if that's the route I'm going with the Tou-Ousen convo, at that point I'd just be better off just not talking about this.
With that said, I think you're just very wrong on the feats part & and hype part related to Karin.
Feats at Coalition:
- She goes up against Tou, he goes up against.... Ordo
- She actually manages to trick the Qin, Tou and Moubu (two Qin 6) literally had no idea what she was up to with her strategy of continuing to use the 1st army. So much so her superior Kanmei had no idea the effectiveness of it.
- Riboku changes up the entire coalition to have her plan be followed. Her plan then effectively becomes the main plan for the Coalition.
- Her usage of formations and armies was top notch.
At Coalition, the arc in which both Ousen & Karin were in, I fail to see how Karin lacks behind Ousen.
Hype for Karin:
- "Genius at Warfare" by Shunshinkun, the commander in chief of the Coalition Army.
- Is selected by Rein to bring out the full potential of Chu's military that Shunshinkun couldn't. Shunshinkun being somebody who stood at the pinnacle of military officers.
- Renpa thinks highly of her
- Kouen thinks highly of her
- Her stats rival Ousen's, and both of their stats progress fairly similarly too.
And only reason we know about Ousen's hype before becoming 6GG, is because he's from Qin. Until her character gets focused you're not gonna get much hype related to her past.
If you really dwell deeper into it, the fact she's younger than Ousen and became the head of military for Chu at such a young... only speaks volumes for her talent. The same Chu which is stated to have a harder standards than any other country for military advancement. The same for Gouhoumei.
No, Ouki specifically called him a commander of unprecedented level. Besides, Riboku was not the prime minister at this point and Ouki had no way to predict he will become one.
You're right at that time he wasn't in the position, few months later he was, however at Bayou he still had the powers that only a PM/CoM does.
He mentions Riboku's title as a Zhao commander. Then mentions he's an enemy of unprecedented level.
You can't pull what Riboku did without having that scale of power lol. He doesn't need to know the position of Riboku, but simply the type of power one would have to possess in order to execute such a plan. Reality is despite not being the PM at that time, he possessed the power to execute a state-wide informational lockdown that requires the authority of the SHK atleast to pull off.
