To listen to Elise to Koukotsu no Marionette , you must visit DLsite (the official platform). As of this writing, the work is DRM-free for downloaded files (MP3/WAV). However, be aware that DLsite requires age verification for R-18 content. Always support the creators by purchasing the work rather than seeking piracy, as doujin circles rely heavily on these sales to produce KU100 quality audio.
