The song's theme is about an imaginary, floating pleasure world, and merely uses the religious term as a comparison.

In interview with Asianbeat on 12 December 2016, MARiA stated that she had wanted to make a song with a Japanese style.

When "Yakusoku -Promise Code-" was announced to be used as the ending theme song of Qualidea Code, she took inspiration from one of its sword-wielding characters, and decided to create costumes with Japanese-style fabrics.

The song aimed to "fuse Japanese and dance" stylistically, with choreography made by Miume.

Dancers from around the world cover the dance and upload their own renditions on YouTube, Bilibili, and Niconico.
