Alyssa Searrs

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