Nya, you make me so happy everyday. When we're not together, I miss you so much that it feels like part of me is missing. Will you be my Yang?”

Yin-Yang Medallion

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.


  • It is unknown if there is a ceremony that follows the initial promise.[1]
  • The Yin-Yang Promise is not the Ninjago equivalent of a marriage proposal.[2] It is a separate thing, and a love-related custom unique to Ninjago.
