Nana Komatsu

Komatsu came to Tokyo, looking to find her dream. Unlike Osaki, Komatsu came from a large and happy household, though her childish outlook prevented her from living on her own initially. She's the middle child of three sisters. Her chance encounter with Osaki began a friendship which changes Komatsu's life forever. She is introduced to Osaki's band, Black Stones, and their members. She later even helps "Blast" to find their bassist, by drawing a poster to advertise the vacancy. Much to her surprise, she also discovers that the members of Blast were friends with the members of Trapnest, a popular rock band of which she's a very big fan.
