Rukia is in the WHERE now?
If there's one thing I know for sure, it's that my mental map of the Seireitei is very wrong, and that there is really no helping this at this point. I also realized that when I think about Soul Society, invariably west is always down, east is up, north is left, and south is right--which like, whyyyy would THAT be the way I orient the map?!
Because of Hisagi's dumb bowl drawing in Colorful Bleach, that's why:
Naturally, I was curious about the directions Ikkaku offers here! Rukia is where?
"the barracks of the Thirteen Court Guard companies"
My assumption has always been that each division's barracks are separate from one another, and exist within the rest of the division grounds. We all assume this. We know we are correct about this. Though it WOULD be hilarious is this massive tower prison was just like, the barrack penthouse and the entire Gotei lived in one very flammable tenement. Also, the Gotei version of Rear Window would be magnificent. But anyway. I guess I assumed the rest of Rukia's Tower Complex was also prison, or that it was part of some amalgamated center where the Central 46 and stuff was, rather than barrack.
So what is Ikkaku talking about here?
Specifically, he says, 各隊の詰所 (kakutai no tsumesho), which he then abbreviates to 各隊詰所, each division's station/post (same "station" as in Coordinated Relief Station). In the Edo period, a tsumesho was basically a rest stop for visiting government officials, or people who were traveling to shrines and the like--a place to overnight, or nap, or wait. In modern parlance, it's kind of like a hostel. So I don't think he means like, the barracks barracks, the primary sleeping locations barracks.
Gotei WeWork
The Wiki article on tsumesho also notes that tsumesho can refer to like, shared office space for factory guards, or people who are coming and going, which makes the most sense in our application. So rather than 'every barrack for every division' I feel like the intention here is "Rukia is in the tower part of the shared workspace/staging area, Gotei WeWork." It makes sense to have one, particularly if this is where the library and reports archives live!
Also obsessed with the idea that the The Tower is just like, next to some crappy portable with one table, a wastebasket, a copy machine with zero toner, a cabinet with a shitton of paper and brushes and ink so you can handwrite your own copies, and a mysterious stained futon that literally every shinigami in the entire Gotei has napped on at one point or another.
But also, I feel like Ikkaku could have been a little more descriptive. "That can't-miss imperious white tower by the giant butte smack in the middle of town," maybe? But I guess if that's not how they talk about that place in their working day, then it's not how they talk about that place in their working day!
I'll also note that in this view, north is actually at the top of the image, unlike in Hisagi's drawing:
In fairness to Hisagi, his drawing was explaining the POV of Ichigo et al having started in West Rukongai. Because they walked up to the West Gate to try to enter the Seireitei, it makes sense that the vanishing point (that which lies beyond the gate; that is, east) would be at the top of the frame. But I prefer to think of Hisagi as someone who would just draw maps like that, because now he's got me doing it, too.
