One piece : The father of makino's baby is shanks

On the cover story of chapter 614, Makino, a close friend of Monkey D. Luffy from his hometown, is seen holding an infant while smiling at the news of Luffy’s return. In SBS volume 63, Oda confirms that the child is Makino’s. He also teases that the father is "probably that person”. There are plenty of fans who believe that the father is none other than Red-Haired Shanks. After all, Shanks and Makino have known each other for years and have a positive relationship. Not to mention that there was plenty of time for Shanks to visit the East Blue during the two-year time skip. Therefore, the likelihood that they conceived a child together is pretty high.
