The title comes from the Japanese word tsuduku, meaning to be continued, and the audio file is credited to Seiji Yokoyama as Sanctuary, Precept of Death. Yokoyama is best known for composing the orchestral score for the Saint Seiya anime, whose dramatic cues are often reused in fan edits. Online, the clip has circulated as an ending sting rather than as a full song, with creators using its unresolved finish to signal that a story will continue in a video. Its formal tone sets it apart from louder meme sounds and helps it feel like a proper episode ending.
