Kurome's Kaiser Frog

This particular Kaiser Frog was one of Kurome's newest puppets revealed during her and Bols' battle against Night Raid. It swallowed Mine whole; however, she managed to survive due to the frog's stomach acid leaking out through a hole which Kurome herself inflicted on it while killing it. In order to get out, Mine blasted a hole in the frog's back with Pumpkin's shot, destroying the beast.


  • Kaiser is the German word for "emperor".
