Creepy ol Ghee lost his bet. Sucks to suck, ratface. The strategy was a clever one though; Mikagami took the fatal attack because he knew that he could take out Paula and that he could give Alice that moment she needed to deal the winning blow against Vivian. I like how this was a fast-paced battle compared to the slow and brutal fights previously. Also, I know Paula and Vivian got backstories to make them more understandable, but as with all the other throwaway characters like the ninja and nun; their stories don't mean anything. Fodder is fodder, nothing more.
Alice is the strongest, confirmed.
