Hatoful Boyfriend BBL speculation, based on something that came up during our last session. This is normally xaq's job, but we just happened to touch on a pet theory I've had for ages, and I really want to forward it because it's something I honestly believe.
[Coo.]Nageki is horizontally bound to whatever anchor point he has, which is why he can't leave the library, but it's already directly stated and common knowledge that he can travel freely along the y-axis. We know that already. So....
The medical center is directly below the library. I'm not going to make an AutoCAD Pigeonation's blueprint or anything, but suffice it to say that with the whole thing about two buildings except they're connected underground, a walled-off entrance to the medical center in one but you can still get there via a secret passage in the other, etc., it's not that unreasonable to think they went through the passage and tunnel and everything and ended up directly below the library.
I refer all of you to entry #3 in the in-game archive.
So, to everyone asking about why Nageki is bound to the library of all things even if he died in the medical center, does it have something to do with the encyclopedia or what, I say this: the entirety of the library is a red herring. Nageki is not, and never was, bound to the library. He is, and always has been, bound to the medical center. The reason why probably has something to do with Shuu preserving his remains down there somewhere. Nageki just traveled upward to the library, and after enough years passed and with the ghost amnesia thing, he just forgot and assumed he must be bound to the library. (Remember that he needs Ryouta and Hiyoko to say or do something to jar his memory on a lot of plot-relevant things.)
This is why later (we haven't gotten that far yet in our second runthrough, but for those who remember it from last time) Nageki is able to appear to Ryouta and Kazuaki during their crazy confrontation in the medical center. Though, if he were bound to his own remains (which were in the medical center,) then he could probably appear pretty much anywhere Ryouta was by that point....
[Oh, and another one.]Also, when you start BBL and it gives you the choice to live a normal live or fulfill the promise ... the "you" in question is Shuu. You are deciding on his behalf whether to begin Operation Hatoful or just stick to the usual level of lower-profile student-murdering and Ryouta-poisoning for another year. He's the one who originally made the promise and Operation Hatoful is his way of fulfilling it, remember?
Unless, of course, my "Anghel is the only sane bird" theory is correct, in which case that's the only bit of normality in the game...kind of an intriguing theory, having the Crimson Angel of Judecca be not the inducer of mass hallucinations, but the shatterer of such, reminding everybirdie of what the world around them actually is.
Of course, this theory's fueled mostly by plot elements from Revolutionary Girl Utena and is one I've almost completely cast aside.
...Could make interesting fanfic material, though.
I liked the book idea (even though there would be no reason for him to be bound to it!), but yes, I think we all agreed by the end of the stream that he was bound to the medical centre and could move up to the library directly above. I'm not convinced about just forgetting, though... the game seems too clever to have anything happen without a more specific reason than that!
I would say that it is too simple for a game like this, [except....]except ... the game already confirms that Nageki has forgotten a lot of things as a ghost, and has attempted to fill in the holes with guesses that are just flat-out wrong. He tells you in the end of his otome route that he's bound to the library because he killed himself in the library, but BBL proves definitively that he killed himself in the medical center. Ryouta even questions him on this, and he backs down to the point of "Well, I did kill myself, I at least know that much...."
