Let's Go Karaoke!

Satomi Oka, the leader of the choir, is suddenly called out by a yakuza to go karaoke to get singing lessons.

Satomi finds himself having nightmares, only for it to worsen when a group of Yakuza ask him for help.

With only several days left until the big day, Satomi continues to struggle as he practices the solo part with his voice changing. At the same time, he also starts to question his feelings for Kyouji as his time with the yakuza was drawing to an end. Satomi's bold move leads him to unforgettable consequences and a sleepless night filled with overflowing emotions.

Left in disbelief, Satomi felt remorseful for the horrible thing he said to Kyouji the previous day. Remembering that it's their big day, he knew there was only one place to go if he wanted to find out Kyouji's current condition and whereabouts. As he steps foot into the lion's den, Satomi crashes the karaoke contest to ask one thing; Where's Kyouji?

Three years have passed since Satomi sang "Crimson" on the big day. Since then, Kyouji was charged with assault for beating the junkie and sentenced to three years of jail time. See the events that unfold after he comes out, along with the changes he notices and experiences.
