The Toy Soldier explains the meaning of SOP by describing Dressrosa's hidden underground world. Beneath the country lies a secret trade port where illegal business is conducted and the mysterious factory is hidden. Captured Tontatta and people turned into toys are forced to work tirelessly there. The rebel force will infiltrate through an underground tunnel the Tontatta spent a year digging. Their goal is to destroy the factory, the port, and all related facilities, defeat the Donquixote Family, and finally return rule of Dressrosa to King Riku. It is an ambitious plan, but its structure is clear: enter the secret world, rescue the prisoners, destroy the system, and restore the stolen kingdom.
