Haha, the V. Akiha guide I wrote up linked in the previous post is kinda outdated now, though some of the strategies still work(all of the combos should still work too). There's a lot of information that I didn't cover that the new school of thought Vermillion Akiha players are doing nowadays(like double OTG) since I can't even do most of that stuff myself. I guess if I decide to pick up V. Akiha seriously again(unlikely) I'll update the guide.
Anyway, this wouldn't be complete without a half assed description of V. Akiha's playstyle. Basically, learn to block well, as V. Akiha is in a world of pain everytime she gets hit. Master the three different TKs(2367a, 2368a, 2369a) and when to use them; since it's V. Akiha, 2368A is probably gonna be the most frequently used one. V. Akiha totally beasts in the corner, so learn all the different methods and combos to get your opponent into the corner as quickly as possible, like, using 623C in combos or doing the 5BB IAD j.BC turnaround combo to get your opponent BACK into the corner when the situation arises. Master the 623B corner loop, as without it, her normal BNB damage is really pathetic. Do tk j.22C at the end of every single 623B loop combo you land, and remember that V. Akiha's 22C lasts much longer than Akiha's, so you want to keep them on the flamepit for as long as possible instead of what regular Akiha usually does, doing a blockstring into flamepit ignition. Learn V. Akiha's OTG finishers off her aircombo ending with j.C, do them when you have 22C set up, and learn the different methods to tech punish it. In blockstrings, remember that V. Akiha's 5C is a frame faster and 2C is a frame slower than regular Akiha's, making 5C that much better in staggering strings and punishing people who try to jump out. And finally, normals of interest; remember that j.C is her best jumpin, with crossup hitboxes, her 6C is an overhead and is dash cancellable on hit, and 2B is just good in general with its clash frames.
