Pirate: the Real Secret Treasure Is the White Moonlight of All Living Beings

I am the last orphan of the Lunaria tribe, They were exterminated, made slaves, and imprisoned in the purgatory of the Celestial Dragons. They say that the Great Secret Treasure is a treasure of gold and silver, the pinnacle of power. Until that devilish boy reached out to me: "I will help you destroy this corrupt world, and you will be my light." It turns out that the ultimate secret treasure of One Piece is, It's never One Piece, But it is the white moonlight of all sentient beings that illuminates all suffering people. And I am his only favorite.
