Alyssa appears as a flash back in Miyu's memory during episode 24. She is the ancestor of Rena Sayers and Arika Yumemiya; as well as Miyu's creator (who in this universe is known as the Merciful Intellegential Yggrdasil Unit). In the flashback, she is depicted slightly older than her My-Hime version, but with her trademark hairstyle. It is likely that "Sayers" is a phonetic derivation of "Searrs" that occurred over time.
