"Hm-mm~" Ai's mood was so flowery now.
She didn't know and didn't care whether she and Ely were one entity, as the Goddess of Life speculated. The only thing she could comprehend from what had just happened, she was officially Elysia's twin sister, and their spirits were bound by a strong bond.
Recalling Elysia's final struggle against the Seraph of the End in the Boundless Realm, Ai feels she owes her life to her twin sister. Because of that, she would never let Elysia get hurt again, no matter what.
'...' Rhea looked at Elysia and Ai with a thought in mind. If Ai is Elysia's other half, like Elena's situation, is Ai also her master?
However, Rhea immediately put that thought aside because she considered Ai was Elysia's twin sister, just like Elysia had believed. Their entities were different, and there were two spirits, not in the case of Oceanid and his ability to divide himself.
