Ano Hi Mita Hana no Namae o Boku-tachi wa Mada Shiranai.

Long ago, young Meiko Honma tragically died and her tight-knit group of friends, shaken by the event, drifted apart. Now, ten years later, Meiko has re-appeared as a ghost that only Jinta, the former leader of the gang and an avid shut-in, can see. All she desires is for Jinta to fulfill her final wish so that she can move on to the afterlife, but with no memory of what it was, it’s up to the teenager to gather his former friends and discover what will allow his beloved friend to rest in peace. With so many feelings left unsaid, can this group work out their strife and help the ghost of the girl they once adored?
