Katejina first showcases her newtype ability in the show immediately after another newtype antagonist kicks the bucket, and said antagonist showed no such ability prior to their return in the narrative while also being newly unhinged for many reasons. Katejina also showed no such ability prior and somehow comes off more disturbed in these later episodes. There are at least some implications in the anime.
