Marisa almost looks like she has a tail in this scene. Just part of her corpse hiding outfit or did she get Mamizou involved?
EDIT: Probably not Mamizou, I also noticed there's badgers on the last page and one of them could've just fallen into the trap. Either it got lured in by the corpse, or Marisa used the berries and mushrooms she was checking out as bait. Though if they weren't badger bait, I'm not sure what the significance of the berries and mushrooms is.
