Reminds me of a BJW match during the BJW/CZW wars gimmick. I don't remember who it was, but I recall someone getting THUMBTACKS headbutted into their forheads. Be glad the artist probably hasn't watched the insanity of BJW.
I still doubt even after that training, that she could match the hardness and durability of Tenko's head.
