The Millionaire Detective - Balance: UNLIMITED (Original Japanese Version)

Haru Kato, a detective working for the Modern Crime Prevention Task Force in the Metropolitan Police Department, has been ordered to work on security at the Classic Car Festival being held in Ginza.

Daisuke and Kato are ordered by their boss to become partners. They find a pair of comedians performing on the street and suspect that they are involved with drugs.

Moments after Kato returns from his business trip and steps out of the bullet train, a hostage crisis occurs on the same train. The suspect has taken hostages and, for some reason, begins live streaming his actions on the internet.

On his day off, a family situation leads Daisuke to break out of his own mansion. Shortly after he steps out, Kato calls him to help a young boy who is distraught over a lost dog.

The president from the Republic of Poliador arrives in Japan, and the Modern Crime Prevention Task Force are assigned to protect the embassy. After a body is found inside the building, the president and Daisuke are forced to the panic room.

Kato takes the heat for the handling of the embassy case. Daisuke checks out the device left behind by the suspect, but for some reason his AI butler, HEUSC, refuses to listen to his commands.

When Cho-san was a member of the First Investigation Division 19 years ago, he and Takei were assigned to investigate the murder of Daisuke’s mother, Sayuri.

Daisuke locks Takei up in the basement of the Kambe residence. Cho-san interrogates him to find out who the mastermind is behind all of this, but Takei is shook with fear and refuses to speak.

Even after those people were murdered, Daisuke claims that this incident is an internal problem of the Kambe family. The rift between Daisuke and Kato has become so serious that they decide to go their separate ways.

Aboard the cargo ship headed for Poliador, a terrorist named Weinski relentlessly attacks Daisuke and drives him into a corner. With all his new gadgets disabled, Daisuke finds himself in a pinch but is saved by Kato.

After escaping from the cargo ship, Daisuke and Kambe pursue Shigemaru and arrive at the old site of the 3rd Laboratory owned by the Kambe group, which is the source of all the mysteries.
