The way Nico bends when she presents you a new Devil Breaker... Priceless.
On a more serious note. I've finished the game on Devil Hunter (normal) mode and what I think is... It's easier than previous iterations. I am glad that it happened in regard to "jump episodes", because sometimes they were annoying, buy not so sure about general difficulty of the fights. I did have to use a few gold orbs with bosses, but otherwise it was pretty easy to get S+ in fights even with just a few skills. Maybe I just became better (doubtful) or maybe it simply became easier.
But iy does not make it a bad game. I still enjoyed it and its a bit more "realistic" visuals. Realistic since it's less vibrant than DMC4 and darker, closer to DMC1-DMC3, yet a bit more serious at times.
