Pseudo corner infinite where Amakusa can loop back into CD off of a close r.236A due to its rage enhanced variant. Only issue is it requires Amakusa be in rage, so eventually the infinite will end because the rage timer will end. Try to end it with WFT before that happens to maximize your damage. In general, though, r.236A allows for a lot of combo flexibility in the corner.
