Let's Go Karaoke!

Middle school student Satomi Oka ought to be proud that his choir group placed second at a national competition. However, he views this achievement as a failure caused by his inadequacies. Furthermore, since graduation is fast approaching, his time as leader of the choir is coming to an end.

While Satomi is preoccupied with his inner turmoil, a smooth-talking gangster named Kyouji Narita approaches him and requests him as a singing teacher. Every year, Kyouji and his colleagues participate in a karaoke competition, where their boss personally designs a tattoo for the loser. To avoid such cruel and unusual punishment, Kyouji asks Satomi to help him find the best song suited for his vocal range.

Albeit reluctantly, Satomi sets his fears aside and agrees to join Kyouji at his karaoke practice sessions. But it remains to be seen whether the mismatched duo will overcome their respective obstacles or fail miserably.
