Her Blue Sky: Aoi Aioi (Part 1)

She's a high school student who is an aspiring musician (an bassist) who was influenced by Shinno. She grew up thinking that her older sister, Akane did not go to Tokyo with Shinno because of her and so she wanted to get her own life by moving out of her town of Chichibu and live in Tokyo instead to start her own music career.
