I had Celeste's number the moment that Hiro's guilt became blindingly telegraphed. Especially because it became pretty clear that Celeste was the one most obviously trying to control the narrative - between corralling all the others to where she wanted them to go at the beginning of the case (and being the one to find the bodies), and constantly reminding them of the obvious factors of Hiro's suspicion. But as I write this, I'm finding it pretty doubtful that it was ever intended to be much of a surprise - the real meat of the story wasn't in the who, but the how. And the how was impressively constructed. Loved unraveling the plot, and if I saw Celeste's involvement clear as day, I definitely didn't see Hifumi's involvement as an accomplice coming. That was really nicely executed.
But yeah, as I said. Satisfying as hell. Really, really fun to piece everything together and nail Celeste to the wall with the evidence. And this might seem a bit of a stretch, but I think the most classically... eh, Ace Attorney of them. Something about the case really struck me as something not unlike what Ace Attorney would do - with you sort of acting as Hiro's defense. It even had the Ace Attorney villainous true colours personality reveal!
I don't feel bad for Celeste, which I imagine was the point, but I really did love it when the facade broke and she revealed her decidedly more... abrasive side. Moreover, what I loved is how she kept falling into and out of that prim French accented voice and her more coarse way of speaking really naturally - like she kept putting the mask on and it kept falling away. That was nicely done, and if that was entirely the voice artist's delivery, major fucking kudos. That was cool. But on that note, I swear to good god, Celeste's angry voice - I know it. It's killing me that I can't pull a name to match it, because I'm familiar as hell with it. If it's really the same person doing both, holy shit.
And despite not feeling bad for Celeste, it was sort of nice, and sort of sad, seeing the mask come off completely. For once in her life, she sounded pretty sincere. And a tinge melancholic. I don't know how it compares to the Japanese equivalent, but I really liked the vocal delivery of her stuff. Resigned, but not checked out.
But, you only have to remind herself she killed two people to relive a Twilight-themed castle fantasy, and you plummet straight back down to earth.
