Ano Hi Mita Hana no Namae wo Bokutachi wa Mada Shiranai.

Synopsis

Jinta and the others think that Menma did not pass on because their feelings were selfish. Chiriko tells them she conspired with Menma the day she died in the hopes of getting together with Atsumu, who she secretly had been in love with since childhood. Tetsudou had seen what happened to Menma on that day and felt guilty about it ever since. After everyone cries, Jinta tells everyone about Menma's dream to talk with everyone, so they suggest they bring Menma to the base; however, Menma has started to disappear, because she had made a promise to Jinta's mother to help Jinta learn to cry. Jinta carries Menma to the secret base, but when he gets there, he loses his ability to see her. As the gang try to search for her, Menma writes some final messages to everyone. After shouting out to her, Jinta and the others are able to see and hear her, enabling them to give their final goodbyes before she disappears. Later, Jinta starts going to school with Naruko, while Atsumo and Chiriko grow closer together. As for Tetsudou, he continues working on his part-time job and also tries to study again. Jinta and his friends return to the secret base and read Menma's final messages while thinking about the flower that blooms in the summer. (Source: Wikipedia)
