Series by 樫本学ヴ

A cheerful boy travels as a Banker. Bankers collect forbidden coins that can summon the Bank King when a bank is filled. He wants that wish-granting power to bring back his father, who was killed when he was young. He sets out to gather coins and faces battles with other Bankers. Along the way, he gains companions such as Worcester, Purinpurin, Risotto, and T-Bone while stronger rivals pursue the same coins.
