Yukio, a snowman, works at Midori's parents' supermarket and comes to live with them. The Yukio and Midori were originally "discovered" by the government after they lost their home due to a giant typhoon and ended up living in Tokyo. Yukio and Midori go on a tour of Tokyo at Akane's suggestion. Tokyo is hot in spite of winter. Yukio is surprised to see vending machines. He says that when he lived in the mountains, he used to be afraid of humans. The people at the supermarket are having a hard time getting to know Yukio, but then an incident occurs.
