Ichigo is starting to show signs of Quincy powers since he just used Blut vene for the first time.
I really don't think Ichigo stands much of a chance here
Negi is far to much for for any HST character at the time. With faster than lightning speed, logia intangibility and city level dc and durability there's not much anyone could to him.
Dont forget he can regenerate has retarded versatility and is pretty darn good with a sword himself. He takes this with low-mid difficulty atm at least. Ichigo might be be able to handle this in the next coming months but atm, he doesn't have much he can do.
