not really I'd say, given what we saw her semblance allows her to move fast but only her whole body, meaning that it is good for distances but nothing we've seen suggest she has faster limb movement (basically she can go from point A to point B really fast but not actuall punch or kick someone really quick)



One thing that she could use it for fighting would be relocating herself, throwing punches and kicks and then using her semblance to step around the enemy faster than they can respond to and combo in a chain of moves (wich would be the better and most realistic way of going ORAORAORAORA on someone than just standing there ORAORAing them)



but other than that, I don't see much advantage for hand to hand





her semblance already complements her fighting style and weapon nicely, using a wide range of movement to add momentum to her scythe
