The Yin-Yang promise is a sacred tradition practiced by the people of Ninjago. A piece of a medallion with one half of the yin-yang symbol is presented to a romantic partner, signifying their promise to be one with each other forever.

History

The Darkness Comes

Jay practices his Yin-Yang to Kai, but he says that he is doing it wrong. When Dareth comes in, Kai tells him, much to Jay's disliking.

Into the Breach

Cole finds out about the Yin-Yang and gives Jay advice, though he unintentionally compares Nya to an old bandage. Later, Jay tries to start the Yin-Yang but is spooked by Garmadon.

Endings

Jay proposes his Yin-Yang to Nya.

Queen of the Munce

Jay mentions it when he introduces Nya to Queen Murtessa.

Distress Calls

Nya mentions it when Jay tries to get her to send a message to Benthomaar.

Trivia

• The Yin-Yang promise was previously stated to not be the Ninjago equivalent of a marriage proposal and a separate love-related custom unique to Ninjago.
  • Tommy Andreasen has stated, "Foreign customs are often hard to grasp. It’s clearly a love thing." When asked if there was a ceremony associated with the promise, he stated, "I don’t know. If we ever decide and is relevant it will be in the show."
  • In an "interview" written by Tommy Andreasen, Nya states that it is "pretty much an engagement".
  • It seems to be equated with betrothal, as when Murtessa asks if Jay is betrothed, Nya says "Yes! He is! To me!"
  • It is treated similarly to a marriage proposal, such as in "Into the Breach" when Kai asks Jay "Did you pop the question yet?", which means to propose.
