Obviously CR with Mami and Lux is an absolute must, and we need to figure out how to make that happen, but it's very likely that Sanae's heard of her as well. She's a priestess of the tree, so has lived a very sheltered life. She does, however, have a lot of respect for the Valkyries, and may have a bit of a senpai crush on her as a result. MAMI'S SO COOL OKAY?
