Arcana

She appeared as Anos's younger sister two thousand years ago. Possessing a source targeted by dragon species, she and Anos constantly moved from place to place to escape from them. Anos had dreams of this life, but in his reincarnated state, he had no memories of Arcana.

In the Selection Judgement, she repeatedly stood before Anos as Selection God Arcana alongside Ahide, but even as a god, Arcana had no memories of Anos. She claims to be the agent of Creation God Militia, who selected Anos in the Selection Judgement.

After Ahide was defeated by Anos, she switched allegiance to become Anos's Selection God and ended up staying at Anos's house because she couldn't return to her original place during the Selection Judgement.
