Satomi Oka

Satomi Oka is the president of the choral club at Morioaka Middle School, currently struggling with anxiety over singing due to his voice breaking. Following a competition, he is approached by Narита Kyoji, a yakuza member, who requests that Oka teach him vocal techniques in order to avoid a severe punishment imposed by the organization. Despite projecting a calm and refined exterior, Oka frequently displays a sharp-tongued and fearless side when dealing with Kyoji. Through their repeated interactions at a karaoke establishment, the two gradually forge an unlikely bond that transcends the gap between their very different worlds.
