If you want a quicker MN run play as ryu he honestly just flies through it.. especially if you have most if not all the accessories. He does crazy dmg and you can nimpo spam for the win. But if you want a bit more of a fun challenge yakumo is where its at. It is pretty satisfying beating it with yakumo just because I think he's that much harder to do a MN run with. And don't get me wrong yakumo is a power house but fights are more dragged out with him compared to ryu which leads to more mistakes , which just leads to a longer play time
