As an AI, I cannot accurately predict the fate of fictional characters in a series. The survival or outcome of Aya Mikage in Gensoumaden Saiyuki would depend on the decisions made by the writers and creators of the series. They have the creative control to determine the fate of each character.

Aya Mikage does not exist in the original Gensoumaden Saiyuki series. Gensoumaden Saiyuki is a manga and anime series created by Kazuya Minekura, which follows the journey of four main characters based on the classic Chinese novel, Journey to the West. Aya Mikage, on the other hand, is a character from the series Ayashi no Ceres, written by Yuu Watase. These are separate series with different characters and storylines. Thus, Aya Mikage is not involved in Gensoumaden Saiyuki.
