Natsu No Arashi! (2009) S1E07

Kaya questions Jun and asks her whether or not she should keep up this masquerade of pretending to be a boy. In the meantime, Arashi and Hajime create some makeshift baseball gear. With all his might, Hajime hurls a ball towards Arashi, who nails it right out of the park...and breaks the weather vane above the coffee house. The weather vane, we later learn is from the prewar days, which brings back a lot of memories to Arashi and Kaya.
