Well, 3C ducks under it (as you probably know). The reason it looks funny is because Mu's 5C takes 14 frames to start up, but the animation makes it look like it hits much earlier. It's one of my bigger complaints about the character, alot of her hitboxes and animations don't quite match up. But your makoto is spectacular at making me second guess my 5C range pokes. It's Mu's best range, but after getting hit out of 5C/jC a few times I get scared and start letting you get too close.
