Created from the concept of "sin" and "becoming an adult". This is the 5th album of Sennzai, who is celebrating the 10th anniversary of his music career. Utilizing the diversity of her voice and her experience in vocal music, Sennzai uses not only Japanese, but also coined words, whispering, multiple recordings, powerful rock, gothic, soprano singing, and more. This is a piece of music that transcends the boundaries of musical genres, gently, calmly, beautifully, and sometimes violently emotional, expressed and colored with all that the current Sennzai has. With a unified concept of the whole album, we have invited composers who are active in the majors, and spun the album with gorgeous production teams such as Rai (Hagall), Yuichiro Tsukagoshi (NanosizeMir), WHITEFISTS, Laur, Feryquitous, kidlit, and bermei.inazawa. The album contains a total of 14 tracks, including newly written songs and each instrumental ver.
