Datsuimajan Idol Sengokujidai Naked Battle Royal (2015)

Legendary idol Yuriko once achieved international stardom. But at the peak of her popularity, she fell ill and passed away. Time passed and producer Piko Muro organized an audition to succeed her as "Yuriko The Second". The winner of the name "Yuriko the Second" would receive a cash prize of 500 million yen and be promised a star career with an annual income of 15 billion yen. Dreaming of becoming legendary idols, or dazzled by the prize money, a group of underground idols gather at the audition site. What awaits them is "Naked Mahjong the Idolater," banned by the James Convention due to its danger.
