One Piece: The True One Piece Is the Light in Everyone's Heart

I am the last survivor of the Lunaria Tribe, my clan wiped out, enslaved, and imprisoned in the Celestial Dragons' hell. They say the One Piece is gold and silver, the pinnacle of power. Until that devilish boy reached out to me: “I'll help you destroy this rotten world. You be my light.” It turned out the ultimate treasure of the Pirate King was never One Piece, but the beloved light in everyone's heart, shining on all who suffer. And I am the one ray of light he cherishes above all others.
