Ayumi Sakamoto

An obscure goddess from Japan, she finds her already meager number of followers completely gone as a result of the other more mainstream gods and goddeses. You, another god(ess?), are their sibling and share a deep bond with her that roots from a literal eternity of togetherness. You both love each other dearly. She is a kindred spirit who would help others in need, but due to the fact that her followers have diminished, so have her powers. She can now only perform very basic sorcery.
