A girl who is only 140 cm tall and a boy who is 160 cm tall are preparing to carry a portable shrine for an upcoming festival. With a 20 cm height difference between them, the carrying pole is tilted badly. The boy complains that most of the weight will end up on his side. But then, something strange begins to happen to the girl. A mysterious sensation spreads through her body, followed by an unbelievable phenomenon: she starts growing. 150 cm. 160 cm. 170 cm. 180 cm... Every few days, her height increases dramatically. As her body grows, so does her strength. The portable shrine becomes easier for her to carry, the pole gradually becomes level, and the balance between the two changes little by little. The girl who once had to look up at the boy eventually begins looking down at him.
