i don’t think shortshortsuper was referring to Seichusen as the stunner, but either way, whether she’s using Abare or Seichusen, Makoto still deals a lot of stun. Just your run of the mill Karakusa -> HP -> EX Hayate does near 50% on the stun gauge. And, if you happened to be near your opponent’s corner, you can add a follow up to the EX Hayate thereby making for more opportunities to inflict more damage and stun (and also regaining some meter).
On to the topic.
One commonly used reset when you have 2 Abares stocked is the following:
Karakusa -> HP -> MK Abare Tosanami -> (super jump cancel) LK/MK Tsurugi -> dash -> standing MP (resets) -> HK Abare Tosanami -> dash -> MP/HP Fukiage -> (super jump cancel) HP/HK/HK Tsurugi
That probably will have most characters stunned or near stunned.
Another combo involving some sort of semi-reset:
Karakusa -> HP -> MK Abare Tosanami -> (dash) HP Fukiage (super jump cancel) -> jumping HK -> (land, then dash under) -> crouching LK -> LP Hayate
This will possibly stun a Shoto and any other character with a similar length stun bar.
note: The jumping HK -> (land, then dash under) crouching LK -> LP Hayate sequence can be replaced with a jumping LK -> (land) kara-Karakusa. At this point, you’ll be in position to land another super (if you have the meter).
Other sequences after an Abare include an early LK Tsurugi -> LP Fukiage -> (super jump cancel) -> jumping whatever -> proceed to reset with whatever
