Jinta, Naruko and Tetsudō look inside Menma's diary, where they find an entry about how the group wanted to make a firework to send a letter to God to help Jinta's mother, though modern laws prevent them from making one themselves. As Chiriko asks Atsumu why he didn't bring up that Menma called the others on that fateful day, he points out it was something that was to be kept secret from Jinta. Jinta's father points him towards a friend of his that can make fireworks, but it's revealed one would cost 200,000 yen to make. Jinta takes up a part time job in order to help raise the money needed to buy a firework, working at Naruko's game store one day and Tetsudō's construction site the next. When Menma hears of this, she overhears Naruko talking about the firework and sees the work Jinta is doing for her. However the next day, the gang learn that the firework maker is no longer able to make a firework for them, under orders from one of Menma's mother.
