University student Wakamizu Ryota gets caught up in a sudden gang dispute. Ryota’s life is saved by the boss of Yanagiba-gumi, and Ryota for some reason ends up harbouring Yanagiba in his own home. Ignoring Ryota who wants him to leave immediately, Yanagiba uses the leftover food in the fridge and starts to prepare a meal without asking. However, the meal is surprisingly delicious despite the leftovers that did not seem possible to combine. This is the beginning of a bizarre communal life connected by meals for a gangster and a university student.
