I don't think I could irl if that were to happen. even with the really sinister ones.
If insidious were to magically come alive, hell no i wouldnt fight him! If he managed a few bites or scratches on me i would be easily poisoned to death x.x. this world would be screwed
With someone like ryukoi, i definitely wouldnt be able to kill. T^T who could kill a little kitten? if anything, i think if she was alive, she would always be nagging me to do something with her or go out somewhere and i would jsut sneeze in response xD (allergic to cats and dogs)
