Yamikin gurentai
Shoji, who moved to Tokyo from Tohoku, meets Daisuke by chance and hits it off. Hoping to make quick money, the two join forces with the yakuza and start a loan shark business, lending money at exorbitant interest rates. Shoji is strong-willed and ruthlessly collects from debtors, while Daisuke is timid and unable to be completely ruthless. Despite their polar opposite personalities, the two get along surprisingly well, and their loan shark business is going smoothly. One day, Shoji is approached by Narimatsu, the boss of a gang, who is like a leader to him, to join the yakuza. Meanwhile, Daisuke discovers that his girlfriend Maika is in debt. With the money from Narimatsu's gang, Daisuke and Maika disappear.
