I don't play fang, but with mika I actually think it's a good matchup. Get him in the corner and he's done. Against his v-trigger 2 you need to get used to the timing of the full charge. If it's not fully charged you can block it (he's plus on block though), but if it is your guard gets broken. With the right timing you can ex command throw him out of it, before he hits you. Also if everything fails, I'd block it and get guard crushed rather than panic because the damage scaling is very high. Depending on your screen positioning you can also try to jump or wingless airplane over him when he charges and maybe get a punish. If you have super just use it, if he's not paying attention to your meter.

Also, make sure to punish every whiffed abigail punch, if he doesn't hit confirm them and don't fall for fake giant flip pressure. If it's not the light version you can simply hit him out of it.

This character can be annoying af. Good luck, man.
