One Piece: Guardian of the Rainbow

This story sprang entirely from a sudden idea about Zoro's “light and sword” concept! The original storyline is its central thread, and the writing recreates the atmosphere of the story in vivid detail. Niji Nino, an original Devil Fruit User with rainbow powers, has a wholly new backstory, and naturally joins the Straw Hat Pirates' adventures. She grows throughout the story, and through the bonds and interactions among the characters, a delicate romance develops between her and Zoro. The original story's core remains intact, without any radical changes, while Niji's own new story unfolds amid a familiar, passionate adventure~
