One day while cruising through space Kiyone calls everyone to the bridge. Nobody responds. Back in Tenchi's house, which has been restored to normal along with Azaka and Kamidakein Yagami's cargo bay Ryoko and Ayeka are taking turns singing on a Karaoke machine. When Kiyone finds out what they're doing she tells them that they've almost run out of gas. When asked why can't they just buy more, Ryoko tells them that they spent all their money on the karoke machine.

So they decide to open a bar on a nearby planet. Katsuhito is the bartender, Ayeka is the hostess, Tenchi and his father are waiters, Azaka and Kamidake are bouncers which keep forcing people into the bar, Kiyone and Sasami are cooks, and Ryoko, Washu and Mihoshi are...female companions. One evening Nagi shows up looking for Ryoko and they tell her that they've never heard of her and give her an expensive bill. After closing the bar on the way home Mihoshi forgot to shut off the gas and their pub explodes. Everyone is forced to flee the planed because the explosion attracted the Jurains. The fleet begins to attack Ryo-Ohki but are intercepted by Nagi who tells them that she will kill Ryoko. While the police are fighting Nagi they all escape.

That night Washu sings a song of scientific song.
