Episode 777 of "One Piece" promises to be exciting when it airs on Fuji TV this weekend as the clan known for its Germa 66 soldiers, the Vinsmokes, are slated to make an appearance. The Vinsmokes are considered to be relatives of Sanji whom he has not spoken to in a very long time.

The Germa 66 soldiers, also known as Warmongers, are humans who have an advanced type of genes. They are both a military arm of the Germa Kingdom and an Underworld group of mercenaries at the same time controlled by the Vinsmokes. The group created an alliance with the Big Mom Pirates as a political move between the Vinsmoke and Charlotte Families.

According to MStars News, episode 777 is closely tied with Chapter 823 of the manga version of the anime. Chapter 823 reveals the beginning of the "Totto Land" arc and eventually introduces Sanji's family.

The synopsis for episode 777 mentioned that Princess Vivi of Alabasta and Princess Shirahoshi of Ryugu will attend the Reverie conference that takes place at least once in four years. The Reverie unites Kings and Queens from all over the world in a single event. It is believed that the introduction of the Vinsmokes will come later in the episode as it will focus more on the events in the Reverie.

In the previous episode of "One Piece," fans saw Sanji taking off and leaving a message for the Straw Hats that he only needs to fix something. While his message also urged his friends not to worry, Luffy and the rest of the group had a strong feeling he had no intention of coming back.

As fans may know, Sanji has been commanded by his father, Jajji Vinsmoke, to marry Charlotte Pudding. Pudding is the daughter of Charlotte Linlin, better known as Big Mom.

"One Piece" episode 777 titled "To the Reverie! Princess Vivi and Princess Shirahoshi!" will air on Saturday, Feb. 18, at 3:30 p.m. JST on Fuji TV.
