Whoops, figured that out. You have to perform the issen, and the issen has to whiff. That cuts the super flash short, and makes it so that your 236AB super doesn’t turn into a DHC. The full combo is, as such, something like this…
5A 5A 5A 5B 5C 6C 623A 5A 5A 5B 5C 6C BC (Issen) Baroque 5A 5A 5B 5C 6C BC (Issen) 623BC BC (Issen, MUST WHIFF) 236BC -> DHC do whatever.
Fucking SICK damage. Shame I’m too lazy to actually master the damn thing.
