I doubt she'll reference Ayu by anything else than the Hamasaki part.
If you check her IG (
https://www.instagram.com/yuhuahamasaki/) you'd see she doesn't touch anything Ayu-related.
She's a pageant queen, if anything. Big hair, blablabla.
The only thing I expect from this is some gays streaming Ayu's songs on Spotify and maybe Ayu inviting Yuhua for some PV or concert.
