Really glad they kept the rapping Japanese. There's only one rap they translate and it's the right one.
Just a warning, don't look up any clips of the show or OST tracks until you're done. There is a SERIOUS problem with hardcore spoilers in the sidebar for basically any Devilman search right now.
Devilman Grimmoire is interesting, like a cross between the manga and the Toei show in regards to content, though keeping the manga's violence. Thankfully they're releasing the original manga in 2 jumbo volumes so that'll be all out well before they finish publishing Grimmoire.
