Holy shit, did Ousen just emote?
Also, how the fuck is the Qin offensive even going to continue after this? Both Kanki and now Ousen have taken huge losses, their armies and command structure decimated, in Kanki's case he bought it himself, Heki and his army are still in Riboku's tickle basement, what the fuck is even left? Yotanwa's shit got rocked a couple times, so she's not in the best shape, but she's around. Tou and Moubu are farting around somewhere as well, I guess.
But as I said before, when the Qin take these massive losses in every battle to raise the stakes, they have to run out of soldiers to get impressively cleaved apart by the dozen by the badass of the week eventually.
