This is the final summer festival.
About
Your childhood friend, Shiori Hosaka, is "dead." The cause was a traffic accident on the way home from the summer festival one year ago. You had crossed the crosswalk first and were waiting, but she never made it across. They said it was a drunk driver. Since then, it has felt like half of your life is missing. By the way, it seems the summer festival is happening again this year. Maybe... it wouldn't hurt to go.
