Hello there. I am not that extensively familiar with Genshin or Dangaronpa, but I wouldn’t mind my girls having potential CR with Albedo and Nanami.

Anya and Isabela have siblings before so they will most likely to give up an arm for Nanami if they have to, while Isabela has a lot of emotional baggage from trying to suppress her own dreams for ages and has gotten the chance to be a weirdo in her own way recently. She and Albedo could be good weirdo buddies.
