Let's Go Karaoke!

At a choral competition, middle school choir leader Satomi Oka is approached by yakuza member Kyoji Narita, who asks him for singing lessons.

Satomi feels despondent about his deepening voice. Later, Kyoji gathers some fellow gangsters at the karaoke box to get singing advice from Satomi.

Wada notices Satomi's vocal difficulties. When Kyoji also has throat trouble, he and Satomi practice apart until the day of their respective contests.

Learning of Kyoji's accident, Satomi rushes to the bar hosting the contest and is upset to see the yakuza members singing as if nothing is wrong.

After serving a three-year prison sentence, Kyoji goes to his gang's office and is forced to attend a karaoke contest being held that same day.
