i feel like the thing with DDC was that the entire game's setting concept started as a joke and he worked backwards from there. first three bosses a merman, dullahan, and werewolf? naming the game kishin's castle? an
inverted castle? i mean...
but while the theming was all really obvious Castlevania jokes, the story was focused entirely on the tsukumogami. which is barely mentioned in the demo outside of the player's weapons, at character select.
he does this pattern a lot, tbh; game theming is generally separated from the game's core story.
PCB: theme was seasons, real story was the cherry blossom trees (core game mechanic)
IN: theme was a false moon, real story was those who came from the moon (mentioned in the intro)
MoF: theme was a mountain in fall, real story was gods (the first three bosses before nitori being gods)
SA: theme was a trip underground, real story was the geyser (again, mentioned in the intro)
etc etc. this goes on. always misdirection, with not much mention given to the real.
so if you want my opinion: the four seasons are absolutely a red herring, as the main theme has been so in every game so far has been.
my bet? it's not the four seasons part that's important, it's the hidden star part.
celestials up to no good, clearly. except more likely celestial
bodies, given the game's title.
finding
this god to be a fairly plausible reference, tbh
