About a year ago, in Aomori Prefecture. Kiyo is spending time with her grandma while getting ready for her and Sumire's departure to Kyoto that evening. Later, Kiyo, Sumire and Kenta have fun reminiscing about their childhood, and Kiyo's grandma serves them a specialty dish from the region to celebrate. Just before boarding the night bus, Sumire discovers what Kiyo has packed from home, as her grandma and Kenta look on.
It's not sandwich but a bread dish.
ليست الشّطائر بل أطباق الخبز
Ist zwar kein Sandwich,
aber ein Brotgericht.
No es un emparedado,
pero si hablamos de platillos con pan,
No es un sándwich,
pero si hablamos de platos con pan,
Ce n’est pas vraiment un sandwich,
mais s’il est question de pain de mie,
Se parliamo di piatti a base di pane, 
i miei preferiti non sono i sandwich.
