sure, OAIL MC isn't Astaroth as the grimoire still exists. but he still carries the soul fragment. and it still affects him. everything else is up to interpretation and speculation.Yes, she has a model...in HS1, which again cannot be transferred directly to HS2 as it has different model variables and art style, hence why I said she and Judie will need a rework.
Point still stands that OIAL MC isn't Astaroth (whose entire schtick was trying to find a way to achieve immortality and thusYou must be registered to see the links), and would want to grow old with his harem. Having him grow old slowly compared to his harem would feel inconsistent with the whole theming that is being hammered to us throughout that game: that going against the natural order of things like death (via resurrection or longevity of life or immortality) is never going to end well (see: the fate of Lillith, Azazel, Lord Magnus, and Astaroth himself), and being more content with life is a better virtue to follow (hence why MC eventually came to terms with not ending up rich and was content leaving the grimoire behind).
anyway, that should left for the thread of the actual game
here, it was just a quick "it would be cool if" hypothesis for a relevant cameo because of the cliffhanger.
and even if the previous models can't be reused, Caribdis can just throw in random models from behind. no need to show their face.
