From what I can tell, this is her j.B, this is her 5B, and this is her sweep.
All of her normals seem to have pretty good range, especially given how fast they are
Her 5A looks to have 4-6 frames of startup, and her 5B and j.B look to have around 10 frames of startup, which is about the same as Yosuke
Her 2B is pretty clearly the hat attack, which looks like it has good vertical range but it doesn't have the same horizontal hitbox as some of the better 2B's out there
I'm really excited to try her out and to see how her weather system influences her play.
God, I can't wait for this game to be out.
