One Piece: A Demon's treasure

The last day of Yggdrasil came, but it wasn't the end of it. Stranded on an island, the Guildmaster of Ainz Ooal Gown would learn the truth of the world she now found herself in. And when she does, new allies and enemies will be forged. But to her, her search for a home has only begun. (Fem/ Momonga) (OC)
