The whole "Rooibos is immortal" thing is not just the school. Rooibos is Rooibos, and she continues to live, perpetually, as a cat that is about a year old--forever.

The school does manifest forms of people they knew over the years. There are also ghosts--Lucy, and it is later implied Anna-Georgina. But Rooibos, neither of those are the case with Rooibos. The cat is just immortal.

I joked on Twitter, back when I was on Twitter, that Rooibos was fae, and decided to declare it canon, while also stating that it will never come up, and that is true. So yes, Rooibos is a fae, immortal cat, but she is a cat and all that that entails, and she is also not immune to being part of the cat distribution system, and she has chosen Anna-Georgina, and by extension the school and whoever is the keeper of the school. I've always imagined that her relationship to the genius loci of the school is friendly, which is part of why she has decided to stick around, but she also just genuinely loves and protects Anna-Georgina.
