It's a wolf v2.0
I'm out if its animated.
A common opinion but I think that's a shame.
I think a big problem with Japanese anime is that they cater and pander so heavily to their audience that it doesn't leave much middle ground, you either love it or hate it. But look at it from a technical perspective, pretty much all their best fiction can be brought to a visual medium at I'd imagine fairly reasonable static costs. While The Lord of the Rings trilogy or HBO Game of Thrones live action representation would be best for anything, it's also extremely expensive and the end result is practically nothing gets made to a visual medium - although that's finally starting to change, but still just scratching the creme off the surface. So I think it's a shame that we can't find some better middle ground compromise.
In regards to Diablo here, and bridging the gap with anime/manga style, I haven't seen that Castlevania series but some Japanese publisher is making HP Lovecraft manga and I think it's style would work well here. Quick google search sample:
