Her Blue Sky

High school student Aoi Aioi lives with her elder sister, Akane, after a tragic accident took their parents away 13 years ago. Because Akane has since been taking care of her single-handedly, Aoi wants to move to Tokyo after her graduation to relieve her sister\'s burden and pursue a musical career, inspired by Akane\'s ex-boyfriend Shinnosuke \"Shinno\" Kanamuro. Shinno was part of a band until he left for Tokyo to become a professional guitarist after the sisters\' parents passed away, and he was never to be seen again.
