One Piece: Starting with Six Treasures Immortal Thief, Stealing the Azure Dragon

Also known as "This Is Clearly One Piece, So Why Does It Feel Like Hitori no Shita!" and "One Piece: I Am the Strongest Creature!" The protagonist receives a mix of good and bad news upon transmigrating. While he possesses a system, it malfunctions catastrophically, stranding him in the brutal world of One Piece instead of his intended destination. His starter gift is the Six Treasures Immortal Thief, one of the Eight Wondrous Techniques, but the associated missions are impossible to complete, requiring feats like joining Mount Longhu or defeating the Celestial Master. Seeking self-preservation in Ohara, West Blue, Charlotte decisively travels to God Valley to intercept and steal the Mythical Zoan Azure Dragon Devil Fruit before its original owner can claim it. Through this bold move, he earns the title of the Strongest Creature on Land, Sea, and Air. Years later, when confronted by Monkey D. Luffy, Charlotte dismisses the Sun God Nika legend with a single Thunder Bagua strike. Even Kaido eventually admits that, for reasons he cannot explain, he has always lived in Charlotte's shadow.
