EP "Zanzou", which comes three years after the EP that made multiple chart appearances and was featured on various playlists across the world, including Japan, Asia, and Eastern Europe, contains five tracks filled with "Japanese Electronica / Ambient." The EP features a fantastical world composed of delicate electronic sounds and ambient noises, blending elements of electronica, ambient, and pop in a well-balanced manner. Despite its dark and ephemeral nature, the music stands out for its grandeur and strength within the quietude. Notably, cokiyu has handled all aspects of the music, including lyrics, composition, arrangement, and mixing. However, the lyrics for the second track, "Watashi wa Hashiru, Higashikaze" were a collaboration with "Maagyu," adding a taste of Japanese Showa-era pop song that is unlike cokiyu's previous works.
