"Halzion" was based on Soredemo, Happy End, a short story written by Hashizume Shunki, marking the first time that Yoasobi collaborated with a professional novelist. Unlike the duo's former two songs, the source material was not based on the novel-centered social media Monogatary.com. The song and the story it is based on were released as part of an advertising campaign Immersive Song Project by Suntory, to promote their new energy drink branded Zone.
