"One Piece" chapter 834 may be featuring an upcoming battle between Sanji and his sister, Reiju. It was speculated that the match will end up with Sanji heavily wounding her sister, and Jajji asking the former for another battle whom he will finally defeat.
In chapter 833, Sanji's backstory was revealed. He had a rough patch with his siblings, which made it hard for him dealing with them. It was also unveiled last chapter that Ichiji, Nichiji, Sanji and Yoji are quadruplets.
Out of Jajji's five children, Sanji appears to be the kindest. He would often be called out by their father for being kind to peasants, or "rats" as what they call them. Throughout his younger years, he was also bullied by his three brothers, and his sister Reiju looked down upon him.
The last chapter left off with Jajji and Sanji's match, where the latter was defeated by his father's electro spear and henchmen. Just when readers thought Reiju was only trying to help Sanji treat his wounds, the former handcuffs the Straw Hat pirate using the Celestial Dragon. The event proved all the more that his sister's loyalty remains to their father.
In a discussion thread posted at Reddit, some fans speculate there is more to Reiju's character. They are guessing she will either help Sanji escape in the end, or she will overthrow Jajji and take control of Germa.
But basing on the last events, it can also be speculated that there will be a battle coming between Sanji and Reiju as the former will have no other choice but to retaliate against his sister in order to escape from his evil family. This will ignite another fight between him and his father, as it can be concluded that Reiju is Jajji's favorite among the Vinsmoke siblings. Their fight will allow Sanji to finally defeat his father and leave Germa to reunite with Luffy and the Straw Hat pirates.
Meanwhile, "One Piece" author Eiichiro Oda admitted that manga is nearing its end as completion is already around 70 percent. He said that only 30 percent of the story has not been revealed and will be unveiled in the succeeding months, KDrama Stars reported via JapNation Manga.
