Superstar wo Utatte.

The protagonist, Oji Yukito, is a 17-year old drug dealer. "I don't know if I can really rap." "I don't have anything to sing about. I don't have anything to… say…" He lost his meth-addicted mother and beloved sister when he was a child, and he was left all alone in the world, except for his best friend, the only one who still believed in him… He is beaten by his boss until he bled, even as he continues to hustle as a drug dealer. What feelings reside in his heart? Highly praised by fellow artists, this is an extreme human drama about people seeking salvation through music. (Source: Shogakukan, translated)
