It’s also a hair comb, part of a pair that was given to her by Azusa when they met on Earth. (TTN “Jurai”)
Interesting, but I’m surprised.
From what I can tell, each Juraians as a Key along with their own Tree, the fact is each key comes from a specific Tree. Ayeka’s is from a branch a Ryu-Oh and so on. So knowing that Funaho and Misaki got their trees at the same time on Jurai, at almost the end of the novel, it seems impossible that Azusa had a key who could control Funaho’s ship, since she didn’t have one yet.
