Light and Shadow! The Darkness Lurking in Dressrosa!

In the Colosseum, Chinjao told Luffy that the King of the Pirates is one who conquers all the conquerors in the New World. He then started crying over his lack of memories of what Garp did to him and demanded an answer from Luffy who knew nothing about it.
Outside in the streets, Sanji and Kin'emon are watching Luffy's fight while observing in disguise the numerous marines surrounding the colosseum waiting to arrest any criminal that exits the stadium. However, not a single loser of the battle royales came out, confusing even the present vice admiral Bastille over what's happening inside.
Elsewhere, Thunder Soldier explains that ten years ago when Doflamingo took over the island, he imposed a strict curfew between humans and toys. Confused, Franky asks why would he separate them like that until the toy soldier reveals that every toy in the island were once humans who became forgotten to their loved ones and that Doflamingo brought a Devil Fruit user that caused those transformation.
At Green Bit, Trafalgar Law is barely holding his defense against Issho and Doflamingo's assault. Their battle is felt shaking the Tontatta Kingdom while the dwarves believed it to be Usopp's Haki. When Usopp questions their war with Doflamingo, the dwarves thought it was a joke and explains that 500 of their people including their princess are held as slaves in Doflamingo's dark factory and their goal is to rescue them and destroy the factory revealed to be hidden in the Corrida Colosseum basement, right underneath Luffy's feet.
