Naniwa Yuukyouden: Nekketsu!! Bakushou Mankai-hen

Original title: なにわ遊侠伝: 熱血!!爆笑マン開篇

Directed by Teruo Kogure

The gang hits up a karaoke bar at night only to cause a ruckus with their less than desirable signing. They soon find out the karaoke bar might close from local hooligans and attempt to rescue it for compensation. A fellow gang member gets involved too deep with a woman--even though he's married.
