Kyou Nukui hasn't missed a single lesson since starting high school. Instead, he spends his days isolated in his bedroom, writing music and releasing it on the internet, accompanied by his sole friend's paintings, an artist going by the alias "Kiriyume." One day, Kyou reluctantly uploads TR03, his newest composition and first break from his usual approach. Furthermore, he uploads under the name "myself" rather than his regular username "HibikiP," and without a drawing from his unknown pal.
