This is a gothic metal album with a new world of contradictory themes of harmony and yin-yang. The song "Dorodoro" is so intense that you can even feel the delicate breathing of the vocalist, and the gorgeous and sad song "Arishihi ni moyuru kimi ga usuki hanabira wo someru mae ni" with its transparent voice and chorus, is in perfect harmony. Other songs that deepen the sense of the world also enhance the immersive experience.
