Saga Idol is a legend

Kotaro Tatsumi (Mamoru Miyano) On the surface, he appears to be an ordinary man, but in fact, he is planning a weird plan called "Zombieland Idols". He crazily resurrected 7 cute girls, turned them into zombie idols, and launched a series of activities. Minamoto Sakura (voiced by Kaede Honda), who is a bit stupid and has lost the memory of her previous life, Nikaido Saki (voiced by Asami Tanoh) who is fiery and loyal, Ai Mizuno (voiced by Risa Taneda) who has a frank and strong personality, Junko Konno (voiced by Maki Kawase) who became a popular idol in the 1980s, Yugiri (voiced by Rika Kinikawa), an active oiran during the Meiji period, and Lily Hoshikawa (voiced by Miumi Tanaka), a genius child ) and Yamada Tae (dubbed by Kotono Mitsuishi) who has not yet regained consciousness and is still in the zombie form. When these seven stars who were active in their respective eras gather together, can they regain their past glory?
