I mean, we only know that Kaguya had a Tenshi moment when she got Eirin to make the elixir, right? 🤔 What was Kaguya's status on the Moon anyway? Was she always a moon princess? Was she really born out of a bamboo stalk?
I do like the idea that she used to be Eirin's student though, which would make her a sort of senpai to the Watatsukis.
