how to beat leroy

How do I play against Leroy as Reina? Honestly, my win rate against him is 0% over many matches, and most often these are games with scores like 3-0 or 3-1. I just don't get it, I watch the replays and there are no clear punishments, only hints to duck.

Every single round against any Leroy is the same. He goes for a high attack where he punches very quickly, followed by a mid-low-mid-low-mid-low spam. When I try to duck, I get launched. When I attempt to attack, I get interrupted. If I play defensively, my health bar depletes quickly because Leroy keeps spamming low attacks. If I manage to break free, it's either a power crush or a parry. And if I go for a hell sweep, I get launched. Controlling space against Leroy is extremely challenging. What am I doing wrong?

I have this feeling that I can't even move during the match because I'll die.

And I can't use FF2 against him almost ever, only as a whiff punishment, otherwise he'll just press parry.
