I’m a Chuunibyou, and I Have Nothing but Invincibility

[Traveling with the crew + recruiting Robin and Nami + Red-Hair-level mastery of all three types of Haki from the start + all kinds of bizarre abilities + massive wars] After transmigrating into the world of One Piece, Luo Xiu discovered that he had woken up in Robin and Nami's bed, and that all the cringe-worthy things he had done in his previous life had actually come true. [On the first day of the first lunar month, you came last in your school's track-and-field race. As you ran, you shouted, “There is only one reason for your defeat: you made an enemy of me.” The Six Paths of Reincarnation illusion is realized!] [On the second day of the first lunar month, you put on a phone case bearing Robin and Nami's likenesses, increasing both Nami and Robin's affection for you!] [On the third day of the first lunar month, you ran to school in the freezing snow, shouting, “I'm going to bring down the heavens!” The Five Thunder Rites: Yang Five Thunders is realized!] [On the fourth day of the first lunar month, you went shopping without an umbrella and called your family to bring you one. After hanging up, you began forming hand seals: “Water Release: Great Waterfall Technique!” The Water Release: Great Waterfall Technique is realized!] [On the fifth day of the first lunar month, while showering, you imagined yourself training and shouted, “Rozan Rising Dragon!” Rozan Rising Dragon is realized!] From then on, Luo Xiu joined the Straw Hat crew as Robin and Nami's devoted protector.
