How to beat Amaterasu?

He was threatening me, lol. Saying he was going to do things to my female family members, and to my butt.

Hide yo’ kids, hide yo’ wife.

Thing about Ammy is that she doesn’t necessarily have gdlk resets or huge combos or anything (at least none that we’ve seen, except maybe the QCF+S Okami Shuffle chain) so the biggest thing to do is learn what your opponent is doing with her and stop that thing. Disrupt their game plan and make them change it up. Switch your own characters around, especially if you feel like your current point is a bad match-up.
