Blade Wing Insect

Kariya’s most deadly and atrocious method of attack consisting of bugs given to him by Zouken. Bugs the size of fat rats shed their skin and transform into winged beetle-like creatures with shiny black armor. These carnivorous insects are ferocious and their teeth are sharp enough to cut through a bull’s bones. A large flock attack Tokiomi simultaneously, but they are no match for his flame and are burned to a crisp.
