This is a documentary that reveals the true face of LiSA, whose many hit songs, including the theme song for "Demon Slayer: Kimetsu no Yaiba," have earned her fans not only in Japan but also around the world. Because of her "humble" but "unbending" way of life, she has been confronted with various realities and has made many mistakes in her life. After such experiences, the girl who admired Avril Lavigne and started a band has grown up to become one of Japan's leading artists, celebrating its 10th anniversary in 2021.
