Leading a lazy life, Fumiya has been a student for 8 years and owes money to loan sharks. One day, a man named Fukuhara comes to collect the loan, which Fumiya cannot pay. So Fukuhara makes a proposition: He will cancel the debt as long as Fumiya agrees to walk with him across Tokyo to the police station of Kasumigaseki, where he intends to turn himself in for a crime he deeply regrets. Not having much choice, Fumiya accepts the deal. Thus begins their journey. Based on the original novel by the 125th Naoki Prize winner Yoshinaga Fujita.
