Comboing after Mizuchi slash portion sucks. The pro kills it so bad, you get a couple j.5Cs tops.
The only good ways I've found to combo off Mizuchi is either 1. RC the second it connects (paralyzes for like 3 second) IAD, land, Zaneiga starter, or 2. let the chain pull them towards you, rapid, micro dash and Level-2 Zaneiga starter. Even then, they're both raw...
There's also the 3. hilariously glitchy opponent teching out of the slashing portion of Mizuchi and then getting reset by the end (where the 3 snakes hit you). It's weird as shit, but it can lead to amazing damage.
