Honestly I don't get most of the school things, other than "Sabi has trouble in school"

That one, I'd say it represents Sabi being alone and marginalized in school?

Also that she's a monster, an experiment like the others, that has been dropped there (that's what I get from those jail looking shoelockers)

Loneliness, despair, weakness. It always looked like she was kneeling, as if from despair or she can't get up. Not sure how far this room is from the kaibutsu-like Sabi room or from the eye room.

Small details, but she has the same palette as Rust and the Rust that turns into a kaibutsu in the final ending. Actual kaibutsu Sabitsuki that attacks you is even paler, however.

I think it's an interesting detail that the room in >>2703 hosts one of the calm twintail Kaibutsu before the Rust chapter. But maybe it doesn't mean anything. Though, I recall there being quite a few empty other rooms in the third floor that lol could've chosen to put this Sabitsuki in, so maybe it does mean something…
