OK ticking off Sofia was a BAD idea, I was doing fairly well challenging her, did the Holy Headpat, and she promptly got mad and wiped the floor with me. Do NOT tick off Sofia! Does explain why Kotone shivers when I suggested Sofia was the DQ though, if Sofia gets mad it's GAME OVER.
She warned me twice for the Demon Layer, she didn't even bother warning me when I did the Holy Headpat, it was "you were condescending to me, time for you to get thoroughly humiliated". Given I was at full spirit (5) and she knocked that out with one move, convinced me to not try Holy Headpat on her ever again! I like the sleepy, friendly Sofia, not the "I'm going to crush you in one move, mad as hell" Sofia!
