[C] - CONTROL

A man with no money uses a certain credit card which grants him access to the surreal Financial District, where he engages in a battle against a man named Sōichirō Mikuni, fighting with mysterious creatures, and is defeated and ends up committing suicide the next day. Meanwhile, a boy named Kimimaro Yoga is working two part time jobs to raise money for his future. One evening as he is trying to study for a pop quiz, he is approached by a mysterious man named Masakaki, who announces that Kimimaro has been chosen to become an entrepreneur at a mysterious bank. The next day, Kimimaro is surprised to find 500,000 yen deposited into his account. Whilst wondering what he should do about it, Kimimaro considers using a small amount so he can attend a kegger with his friend, Hanabi Ikuta. However, as he withdraws the money, he is once again approached by Masakaki, who places him in a taxi bound for the Financial District.

Kimimaro is brought to the Financial District in which he must participate in Deals, battles in which money is wagered, using an Asset named Msyu. Kimimaro and Msyu are instantly thrown into a Deal against a powerful Asset named 'Gig'. With Kimimaro not able to understand the situation, Msyu takes a lot of damage defending him. However, Msyu manages to teach Kimimaro how to use her ability, which manages to defeat the opponent, though he passes out soon afterwards. Kimimaro returns to the real world, where Masakaki informs him the next Deal will take place in a week's time, and soon finds he has even more money in his account. Later on, Kimimaro starts noticing that some money bills appear black for him, which Msyu explains is money from the Financial District. Kimimaro then ends up encountering Mikuni, who explains about the black bills, known as Midas Money, and hints that he knows of Kimimaro's father.

While searching for clues about why he was chosen, Kimimaro makes an unsettling discovery in a notebook filled with numbers in his family's storage.

Kimimaro learns how devastating consequences can be as the result of a desperate wager against one of his own professors.

Kimimaro learns that keeping a tight margin during a deal is a gamble without Mashu's trust.

Kimimaro's new approach to deals pays off, but his next opponent offers him a bribe to forfeit.
