I know blargh posted this in Naoto's Dustloop section but I felt like sharing here as well for the sake of discussion and since seeing the Naoto section being dead makes me sad, but what can you do if the game isn't released on consoles for us baka gaijin to enjoy yet? XD
Anyway here you can see the Naoto player use Hamaon on an opponent. Now any player playing against Naoto will most likely block on reaction when they see her use it straight up, for those who are not aware of what it can do may not realize is that if you're caught blocking it, it basically gives Naoto a free Rock-Paper-Scissors type mixup. In the video, the Naoto player did 'Hamaon > All Out Attack' as the Labrys player was waking up and since the Labrys player failed to the block the AOA correctly, she ate Hamaon's remaining hits and was insta-killed.
Pretty interesting stuff, makes me wonder what else you mixup. Also, the fact that Hamaon's blinding light makes it hard to visually see the what mixup Naoto is going for is just icing on the already delicious cake that are Hamaon mixups. Anyway here's a couple of theoretical Hamaon mixups that might work.
-2A or 2A+B (low mixup)
-forward jump in into any jump attack that must be blocked high (high mixup)
-forward jump in into 2A or 2A+B (low mixup)
-forward jump in into AOA (high mixup)
-forward jump in into grab
-Air Grab (on blocking airborne opponents)
-Megido trap cross up
