>>58713285I'm pretty sure it's Kobo right now. A lot of the ReGlass members sound like existing Holos sharing a character.
Ririka alternates between sounding like Choco, Marine, and Chloe.
Ao-Kun is A-Chan.
Raden alternates between Fubuki, Pekora, and Marine.
The other one seems like it's Nene and Aqua.
Hajime is Kobo and Iroha.
