well for starters, this means dmc2 in no longer the canonical end of the dmc series, so that's cool, also means dante escaped from hell after the end of dmc2 which raises a bunch of questions, and it also mean lucia might return in some capacity, which would be awesome!
@HHH816 yeah that really doesn't add up but dmc timeline is kinda all over the place, curious to see what their explanation is, probably something along the lines of "time passes differently in hell" or something like that
