Looks like Monster Hunter. Longsword on back, slinger on arm, I think I've even seen that exact combination of beads and necklaces in one of the games.
I haven't play GG Xrd yet, but i assumed this, she intends to do some kind of jump/move cancel to counter sol's attack, but instead she got the timing wrong and get probably the jump + P or something, which is a norm and easy move.
She was trying to get a lewd-looking trade animation, but got the timing wrong and whiffed a jumping H. That's what I get from it, at least.
