Long-running Japanese anime "One Piece" excites fans as the fight between Big Mom and Brook progresses. Spoilers reveal that Luffy is finally out of prison, and he will do everything to save Sanji.

To recall, episode 820 featured the fight between Tamago and Pedro wherein Tamago regenerated into a stronger form that is known as Viscount Hiyoko. Meanwhile, Brook is still fighting with Big Mom in the Room of Treasure. Brook failed to pierce Big Mom's skin and he was defeated, but he already managed to damage Prometheus.

In this episode, Luffy broke out of prison. To make sure that Big Mom will not learn about it, Smoothie ordered the floors below them to be blocked off. With Luffy out, he fought against Charlotte Cadenza with the goal of finding Sanji. Luffy choked the pirate to get Sanji's location.

Meanwhile, in the infirmary, Reiju encouraged Sanji to escape. It was also revealed that the bomb cuffs of Sanji are fake. Reiju said that she replaced it with duds, which means Sanji can leave without repercussions.

In the upcoming episode 821, it will highlight Luffy as he will try to move through the hideout of Big Mom. The Straw Hat Pirates leader is full of wrath with the goal of saving Sanji from the wedding. But before he can go to Sanji, he will be fighting with some officers.

The preview of the next episode, titled "The Chateau in Turmoil! Luffy, to the Rendezvous!," hints that Luffy will retrieve Sanji while Jinbe and Nami will be running around inside the castle. Luffy will be in a rush to go to Sanji since he needs to tell him about the secret of the wedding. While fighting with enemy officers, Luffy will see Reiju who will suddenly show up.

Based on the manga, Reiju will tell Luffy that her brother already knows about the plan of Big Mom. She will tell Luffy that Sanji overheard Pudding talking about their plan. After knowing that, Luffy will decide to wait for Sanji to reach to him first.

"One Piece" episode 821 will air on Sunday, Jan. 14, at 9:30 a.m. on Fuji TV.
