This unit competes in a nationwide idol battle royale to succeed the dissolved top group, Fool's End. Successorship hinges on aggregated metrics encompassing music sales, live performance attendance, and merchandise revenue. Each competing unit is led by a music producer who is the reincarnation of a Sengoku-period general; No Princess is guided by Shigemichi Saitō, the reincarnation of Saitō Dōsan. Kurumizawa's involvement unfolds during events like the Kawanakajima Festival, which serves as the opening battle in this succession race.
