My-Otome Anime
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. Arika's hair glows in the same manner as Alyssa's when she activates the ultimate weapon of her robe, the Sword of Akatsuki, and that when Miyu looks at Arika or seemingly any descendent of her creator she sees glowing hair.
Miyu is almost always seen with a small yellow bird named Alyssa, who shares her human counterpart's hairstyle. Miyu is able to team up with the bird (who somehow carries the genetic imprint of Alyssa Searrs, as Miyu's start-up screen indicates) and execute attacks with her "Maria" sword arm as well as "Artemis", an energy sword slash. In the activation process of Miyu's sword, Alyssa's name is spelled 'Alissa', suggesting that in the Otome Universe, her name (as well as the names of several other characters) has been romanized differently.
