Makino’s Child Theory: Shanks’ Son Gets the Straw Hat

With the Final Saga now in full swing and Oda methodically closing every narrative loop he opened decades ago, one theory circulating in Japanese fan communities has stopped readers cold: the child Makino was tending to in Chapter 1 — the very first page of One Piece — is Shanks’ son, and Luffy will pass the Straw Hat to him in the final chapter, mirroring the exact moment Shanks placed it on Luffy’s head. If this theory is correct, the story’s ending has been hiding in plain sight since 1997, and the entire saga becomes a single, unbroken relay race of inherited will.

The Theory

The stakes here are enormous. One Piece has always been a story about inherited will — Roger passed it to Whitebeard, Whitebeard announced it to the world, Shanks handed it to Luffy. If the final beat of the story is Luffy passing the hat to Shanks’ own blood, it would mean the Celestial Dragon lineage (Shanks is theorized by many fans to be of Celestial Dragon descent) is ultimately redeemed not by power or privilege, but by living freely — just as Luffy did. The thematic circle would be complete.

Evidence from the Manga

1. Chapter 1 — Makino’s child appears without explanation: In the very first chapter, Makino is shown tending to a small child in Foosha Village. Oda is famously deliberate about every detail he includes in Chapter 1 specifically. This child is never named, never explained, and conspicuously present. For Oda to include an unnamed child in the story’s opening page and never follow up would be wildly out of character.
2. Chapter 1 — Shanks visits Foosha Village and spends significant time with Makino: Shanks and his crew are stationed at Foosha Village for over a year before the chapter’s events. Makino, the bar owner, is their primary point of contact and is shown with warmth and familiarity toward Shanks. The timeline makes a romantic relationship — and a child — entirely plausible.
3. Chapter 1 — Shanks’ promise: “Make sure you return it to me”: Shanks tells Luffy to return the Straw Hat only once he has become a great pirate. Luffy has now sailed across the entire world. The hat has not yet been returned. This promise is one of the most sacred unresolved threads in the manga. If Shanks dies before Luffy can return it, someone must receive it in his place — and his own son would be the most narratively resonant choice.

📌 Key Evidence: Ace, Sabo, and the broader pattern of Luffy’s world consistently features characters with pink or non-red hair emerging from the Red Hair lineage. The theory posits that Shanks’ red hair diluted by Makino’s genetics would produce a pink-haired child — and notably, both of Luffy’s brothers (Ace and Sabo) sport dark-to-auburn tones while characters connected to Shanks through indirect lineage skew toward warmer, lighter hues. This is speculative but visually consistent with Oda’s color logic.

📌 Key Evidence: One Piece is structurally a story of inherited will, not inherited blood. Roger → Whitebeard → the world. Shanks → Luffy → ???. The series has primed readers to expect one more link in this chain. A child of Shanks receiving the hat from Luffy would merge the “blood” and “will” threads simultaneously — Shanks’ literal son carrying Shanks’ symbolic legacy forward through Luffy’s journey.

Our Analysis

What makes this theory genuinely compelling — beyond its emotional elegance — is how well it resolves two of One Piece’s most tantalizing loose ends simultaneously. The return of the Straw Hat has been an open narrative IOU since page one. Shanks’ fate in the Final Saga remains deeply uncertain, with many readers convinced he will not survive the endgame. If Shanks dies before Luffy reaches him, the hat can never be “returned” in the literal sense. But Oda rarely lets a promise die unfulfilled — he transforms them. Luffy passing the hat to Shanks’ son is not a failure to return it; it is the most complete return imaginable. The hat goes home to Shanks’ blood, carrying Luffy’s entire journey inside it.

The Celestial Dragon angle adds another layer of thematic richness. If Shanks is indeed of Celestial Dragon lineage — a theory supported by his mysterious past and the World Government’s peculiar deference toward him — then his son would technically be born into the world’s most corrupt bloodline. Yet that child, raised in a small island village by a kind bar owner, shaped by the stories of Luffy’s adventure, would grow up to embody everything the Celestial Dragons are not. Oda loves this kind of inversion: the mightiest pirate king came from the most humble origins, and the heir to the most privileged bloodline inherits not power, but freedom.

The primary counter-argument is that Oda may simply have drawn a background child in Chapter 1 without long-term intent — artists sometimes add incidental details that take on meaning only in retrospect, if at all. Additionally, Shanks and Makino’s relationship has never been explicitly romantic in the manga; it reads as warm but professionally cordial. However, Oda’s track record of seeding details decades in advance — Pluton in Alabasta, the Road Poneglyphs, even Luffy’s Devil Fruit being renamed in Wano — makes it genuinely difficult to dismiss any named Chapter 1 character as accidental background noise.

Theory Credibility Rating

The structural symmetry is nearly perfect, the unresolved promise of the Straw Hat demands a resolution of exactly this emotional magnitude, and Oda’s established habit of planting final-chapter seeds in Chapter 1 gives this theory far more weight than most — the only thing holding it back from five stars is the absence of any explicit confirmation that Shanks and Makino share a romantic history.
