The song begins with a cold and mysterious industrial sound like a Guillermo del Toro film, inviting the listener into a foggy labyrinth. As a guide, voice actress Aya Gomazuru is a featured guest. In pursuit of a lost shadow, she heads for the city of mirage. Somewhere in her heart, she knows that she will never be able to touch that shadow again. Still, in her fading memory, she continues to search for the shadow. The line between memory and delusion gradually becomes blurred, and the frozen nightmare torments her, but at the same time exists as a source of sustenance for her life. And so the labyrinth continues.
