Karaoke Iko!

Satomi Oka is more concerned about the final choir competition of his middle school life than anything else—until a stranger approaches him from the shadows with the demand, “Let’s go karaoke!” Kyouji Narita, a yakuza, is not easily intimidated, but he has a dire reason for seeking out Satomi: the boss is hosting a karaoke contest, and the loser will be forced to endure a tattoo applied painfully by the boss himself. Oka has spent years in vocal rehearsals, but nothing has prepared him for private karaoke sessions with a gangster.
