Summer approaches, and money remains very tight. Suddenly, Yuki falls off a stool while trying to reach for something and dies. At that time, Akira was playing baseball. The children are shocked, and Akira has to go find Saki to borrow money in order to buy a dozen or so boxes of Yuki's favorite chocolate candies which are then placed with Yuki's dead body and stuffed bunny into a suitcase. Akira and Saki then take the Tokyo Monorail to an open field near Haneda Airport's runway and bury the suitcase containing Yuki in a hand-dug grave. The children's lives then go on as usual, and the film ends with Akira, Kyōko, Shigeru, and Saki still together walking home..
