What's Toya thinking about today?
It's... Emu's older brother??
For context: one of my favorite, I guess series, of PRSK fanfic that I've read revolves around Toya's older brothers (he has bio siblings for anyone who doesn't know, we just don't know what they look or sound like, nor do we have any names for them). It's fun and I like seeing their dynamic. Iirc, one (or both) of them calls Toya "Little Maestro."
And one of them, don't ask which I don't remember, just so happens, to be exes with Shousuke Otori, Emu's second eldest brother.
