故事背景设定在 20XX 年的日本，国家背负着巨大的财政赤字，被称为是经济崩坏、日本的末日。但是，某个叫做“Sovereign Wealth Fund”的新兴政府系金融机构，凭着成功运用政府资金，实现了财政再建的奇迹。另一方面，虽然政府经济复苏，但长久以来所引发的社会现象却不会因此消解：年轻人的就业问题、裁员与失业问题、面对未来的绝望感、逃避现实、结婚率下降以及少子化、还有失业者因此自暴自弃而引发的无差别暴力事件、失踪人口与自杀人口的激增……

某一天，就读都内经济学部的大学生余贺公麿面前，出现了一名神秘男子，询问道“以你的未来作为抵押借给你金钱，你将会如何利用自身才能去使用这笔钱？”公麿的人生自此展开了重大转变。

慶応四年――幕府軍と薩摩軍の争い“鳥羽伏見の戦い”が始まった。土方は前線で指揮を執り、山崎は隊医として負傷者の救護にあたる。しかし圧倒的に不利な銃撃戦、淀城の薩摩への寝返りと、苦戦する新撰組は次第に追い詰められていく。 一方で、思いを寄せる少女・沙夜を身請けするため奔走していた鉄之助は、隊を離れたまま幕府軍大敗の知らせを聞く。自分は何のために新撰組に入ったのか――屯所へ来て間もない頃、山崎と交わした会話を思い出した鉄之助は、もう一度刀を手に、隊へと戻る決意をするが……抗うことの出来ない運命の戦いが幕を開ける。

Money is power, and without it, life is meaningless. In a country whose economy is in shambles, second-year Economics university student Kimimaro Yoga understands this fact all too well, as he is surrounded by the relatively luxurious lives of his peers and struggling to make ends meet. However, his world is turned on its head when a stranger in a top hat arrives one late night at his door.

Going by the name Masakaki, the visitor petitions Yoga to come to the Eastern Financial District, a place where money flows in abundance if one offers their "future" as collateral. Although reluctant, greed triumphs reason and Yoga accepts the offer; thus, taking on the mantle of an "Entre." But unbeknownst to him, the land of wealth he has entered is an alternate realm built in the likeness of his own, where Entres are forced to participate in weekly duels called "Deals," with their collateral at stake. Pitted against his countrymen and fate, Yoga must quickly adapt in this new world if he hopes to protect his fortune and future—and discover just how much money is truly worth.
