Kurahara Kakeru runs through the city streets at night. A single man chases after him on a bicycle. That man’s name is Kiyose Haiji. When Haiji catches up to Kakeru, he asks him a question: "Hey, do you like running?" Led by Haiji, Kakeru arrives at the Chikusei-so student dorm. He meets the strange residents living there. Haiji behaves in a peremptory manner. Kakeru is bewildered by the sudden development. No one at the dorm is aware of Haiji’s ulterior motive. That night, the residents hold a welcoming party for Kakeru. At the party, from Haiji’s mouth comes a grand and reckless plan. How will Kakeru respond…?

"The residents of the Chikusei-so will run in the Hakone Ekiden together." Kakeru responds strongly to Haiji’s rash suggestion. All the residents are amateurs when it comes to long distance running. Nobody takes Haiji’s words seriously. The residents attempt to carry on with their college lives, but Haiji’s shadow approaches. Threatened by Haiji’s mysterious pressure, several tragically fall to Haiji’s hand. Kakeru tries to leave the Chikusei-so, but he runs into Nico-chan in the city. Meanwhile, the Chikusei-so’s bath breaks for unknown reasons, and they decide to go to the "hellish" public bath instead…
