The Battle of Love! The New Leader Sai vs. Baby 5!

Luffy and Bellamy continue their confrontation. Meanwhile, Baby 5 mistakes Sai's words as a proposal, while Chinjao struggles against Lao G's Geo-Fist techniques. Hearing Sai's and Baby 5's conversation Chinjao, also misunderstanding, reminds Sai he's arranged to be married to the daughter of the Niho Navy's leader to form an alliance. When Baby 5 asks Sai how to be of use to him he jokingly tells her to die, which she responds by happily preparing to commit suicide. In a flashback, it's revealed that as a young child, Baby 5 was abandoned by her mother who called her useless and unwanted, which is why she is willing to do whatever's asked of her as a way to feel needed. Not wanting to win this way, Sai tries to stop her, but Chinjao attacks him for trying to help an enemy. Sai counters resulting in Chinjao's head drill getting bent, before slapping Baby 5 and telling her to value her life more. Chinjao awakens and instead of being angry, is proud of Sai for surpassing him and officially dubs him the head of the Happo Navy, promises to break off Sai's engagement and bestows his technique on Sai's leg, before being struck down by Lao G, who had used a technique to restore his body to its prime. In retaliation, Sai challenges Lao G. Sai declares to take Baby 5 as his wife before defeating Lao G with his grandfather's "Drill Dragon Nail" technique.
