I think the broke naginata adds to the creep factor. She's been the character that has my most interest. Being what she is, along with her being the shortest character this season of 5'4"
Adams comment of her stuff being "never done in ki before" followed by keits saying in chat that it wasnt just never in KI, but "never done ever" makes me INCREDIBLY curious
