As Doflamingo Don Quixote and Trafalgar Law battle on the Iron Bridge, the Straw Hats divide and...try to conquer. Luffy sends the group on the Sunny to Zou while Usopp, Robin, and Franky learn of the Tontatta's horrible history. Meanwhile, underneath the Colosseum, the defeated contestants find a fallen king amongst them and learn what really happened during the darkest days of Dressrosa.
