Kyoukai clearly won't beat her unless she reaches Houken tier BSing, but at the same time I can't see the end results looking good as a reader perspective. Either Kyoukai beats her unrealistically or Shin defeats Kyourei, if it's the latter then Shin will step in to save Kyoukai AGAIN when she's too weak to do it herself, the second time in 50 chapters. Although this might bring a smile to some who dislike her being this powerful, at the same time it kind of paints her weak & useless.
I mean I will always trust Hara but I'm just disliking this mini-arc, we cut the 3 States arc short for this? Smh. Hopefully this'll get resolved in the next 10-15 chapters max and we move on towards real-time history adaption.
Also, how is no one else in the Ousen Army acknowledging Kyourei's arrival and met with Shin about this? Kanki's army probably wet their pants after hearing what she did lmao but no reactions from Mouten, Ouhon, Ousen, etc? Lol.
