National Audit Bureau member Hajime Matsudaira (Shinichi Tsutsumi), Tadako Torii (Haruka Ayase) & Asahi Gainsbourg (Masaki Okada) travel from their homebase of Tokyo to the city of Osaka. Their mission is to discover any financial irregularities & to ensure the correct use of federal money in the Osaka city government. Their initial audits go smoothly, but things turn more interesting once they enter the Karahori shopping district - the area with a long history reaching back to the Meiji era.
