2a 2b 5bb 5c 2c 22a 5c j.c ad j.c j.236c (land) j.bc dj.bc 236b 5275 dmg
I just tried this one in training and I don't think anything can beat it for H-Ryougi. Did ~5760 when starting with j.c
Rekka overhead combo:
(blockstring into 236a/b) 214b 236b 5b 5c jc j.b j.c djc j.b j.c j.236b ~3216 dmg
Knife crossup combo w/catch:
(blockstring) 63214b 5b 5b jc j.b j.c djc j.b j.c 236b ~3735 dmg
63214b seems to automatically release the knife at the same spot as long as you're ~5b length away from the opponent or greater. She'll run a little automatically to correct the distance. Any closer and she'll be too far to land 5b after the knife. Substitute 5c for the 2nd 5b to do more damage, but you won't be able to catch the knife. Doesn't work if opponent is all the way in the corner.
Can probably add some tk236c after the launchers in those for more dmg. Also, is there any specific reason why most are going for C-Ryougi? Personally liking H a bit more.
