not really sure what Zentos is arguing here... it's a fact that Karin is playing around and still managed to win her encounter with Tou.
Let's just say that both Tou and Karin have no real amazing result, and yet he says Tou is good because Ouki and GHM says so, while Karin is bad even though Riboku, SSK and SHK says she's good
tbh, no matter how I like Tou, it's still a real fact that Karin beat him easily. She only fails her "elites capture gate" strategy because Ordo got screwed up really badly by Ousen. Totally not her fault at all. Ofc she didn't need to kill Tou and Moubu army herself because it's not the point of the battle. Trying to massacre them all pretty much means that Chu's own troops will took a lot of damage from Tou and Moubu. Not to mention they will needs more than 5k elites because the reserve behind the gate would be perfectly prepared for them to come
