Ep 715. The Manly Duel! Senor's Elegy of Love!

Luffy and Viola continue their search for the missing Straw Hats, and they come across Kin'emon and Zoro who have been frozen in stone by the Donquixote Pirates. Meanwhile, Senor Pink challenges Franky to a duel. The two exchange blows, but Franky ultimately gains the upper hand.

However, Senor Pink seems unfazed by his defeat and begins to sing a song about his lost love. As he sings, he reveals his tragic past and how he lost his wife and child. Franky, moved by Senor Pink's story, decides to let him win the duel as a sign of respect. Senor Pink is touched by Franky's gesture and begins to cry.

Elsewhere, Law navigates his way through the underground harbor in search of Doflamingo's factory. He encounters a group of Donquixote Pirates who try to stop him, but Law easily defeats them with his powers. In the middle of the fight, Law receives a call from Luffy and informs him of his progress.

Back at the battle between the Straw Hats and the Donquixote Pirates, Bartolomeo and Cavendish join the fight against Gladius and Lao G. Bartolomeo creates a barrier to protect the Straw Hats from Gladius' explosions, while Cavendish uses his speed and agility to take down Lao G.

Just as everyone thinks the battle is won, Dellinger and Machvise show up to join the fight. Dellinger proves to be a formidable opponent with his Fish-Fish Fruit powers, while Machvise's immense size and strength make him nearly invincible. The Straw Hats and their allies struggle to keep up with their opponents, but they refuse to give up.

As the battle rages on, flashbacks reveal Senor Pink's past and the reason for his unorthodox fighting style. Senor Pink's love for his wife and child is what gives him the strength to continue fighting, and in the end, it is what leads Franky to show him respect.

The episode ends with Law finally finding Doflamingo's factory and preparing to enter, unaware of the dangers that lie ahead. Meanwhile, the battle between the Straw Hats and the Donquixote Pirates continues to escalate, with no end in sight.
