Maestro of the ultimate power, Eid.
Everyone in the El Search Party was able to overcome their trials from the Hall of El. When everyone comes back, Ain feels proud of their strength. Ain begins to understand that he himself is also quite similar to other human beings, and should be able to choose for himself what path he takes. Now he begins his journey with the El Search Party again, his existence itself acting as proof of communion between humans and god.
