Ikebukuro West Gate Park starring Tomoya Nagase is back with a special episode. Yosuke Kubozuka, Ai Kato, Satoshi Tsumabuki, Kenji Sakaguchi and others gather again. Three years have passed since Makoto Mashima put an end to the Ikebukuro street gang conflict. Threatened with eviction, Makoto has to switch Mashima Fruits to a mobile operation, selling fruit out of a truck. Takashi has stepped down as King of G-Boys and runs a ramen shop called King Ramen, while Doberman Yamai is currently in prison for the murder of three of his friends. One day, a homeless man visits Makoto. He wants him to catch the culprit behind the serial homeless attacks occurring in Ikebukuro. Makoto, who does not want to get involved in troublesome things, tries to refuse, but it is not going to be that easy.
