Also this is the rarest cut-in in the entire game, right? Carole without her mask being excited? It's so impossible to happened because even when she takes her mask off, she is always embarrassed and shy, so she wouldn't make an excited face shout.

The second rarest one is probably Maria's shocked face. The third being Yunyun's smile with the fang.
It could have been Wakki without the eye-patch, but in 5.2 that happened a lot.
