The Millionaire Detective - Balance: Unlimited (Japanese: 富豪刑事 Balance:UNLIMITED, Hepburn: Fugō Keiji Baransu Anrimiteddo) is a Japanese anime television series produced by CloverWorks,[2] directed by Tomohiko Itō and inspired by the novel The Millionaire Detective written by Yasutaka Tsutsui.

Daisuke Kambe, a detective with extreme personal wealth, is assigned to the Modern Crime Prevention Headquarters.

Detectives Haru Kato and Shinnosuke Kamei from Japan’s Modern Crimes Prevention Task Force are asked to assist security during a festival, where First Division officers are trying to locate a bomber targeting a foreign prince.

The ridiculously wealthy Daisuke Kanbe meets the Police Superintendent, Haru, and requests a place on a squad of his choice.

During their pursuit to stop the bomb-containing van, Daisuke inflicted damage on nearby vehicles and public facilities.

They learn that the narcotics came from the organized crime group Gondawara Gumi, run by mob boss Umezu.

Kato’s former Division 1 colleague arrives, causing him to flashback to an incident that rendered his gun-shooting abilities useless.

Instead, Kato has HEUSC hack the man’s emails and learns he aims to win prize money from Chaintube by reaching 10 million views so his sick sister can have surgery.

Daisuke realizes that having stormed out of his house in a bad mood, he forgot the earring he used to contact HEUSC and lost his phone.

The task force is assigned to protect President Alvarez of Poliador, as there are concerns that terrorists want to kill him.

Alvarez wants the Kanbe family’s help to modernize Poliador but faces tough opposition from indigenous protestors.

Haru catches the murderer, who disposes of the only key to the safe room down a drain, hoping Alvarez’s death will prevent the dam from destroying his indigenous land.

Haru manages to save them, having realized the janitor had a secret spare key and had been using the panic room to hide his dirty magazines.

HEUSC successfully hacks Imura’s laptop during her interrogation, only to suddenly inform a shocked Daisuke he lacks the clearance to access specific folders due to their connection to the Kambe Group.

Kato learns from Kiyomizu that the last time Nakamoto investigated Mizuo, it was due to the murder of Sayuri Kambe, Daisuke’s mother.

Nakamoto received no help from the Kambe family and instead stole a photo album from which a witness identified Shigemaru as the murderer.

Nakamoto found a locker key in the album marked with the symbol for Adollium, a dangerous material Shigemaru had been researching.

Takei located the locker while Nakamoto learned Shigemaru committed suicide, followed by the key being stolen from his desk.

Takei is gassed in his vehicle and experiences vivid hallucinations of Imura accusing him of her murder, fearing for his own life if he didn’t sabotage the Sayuri investigation and tricking him into calling Director Saiki.

He awakens in Daisuke’s home, the hallucination having been created by an advanced virtual reality headset to trick him into revealing who he was afraid of during the Sayuri investigation, his own father-in-law Director Saiki.

Nakamoto explains that he never discovered Shigemaru’s lab's location, and now it no longer even exists in the Kambe Company’s records.

Kato discovers the lab in a Kambe owned mansion in the mountains, and Daisuke decides to infiltrate in secret.

Suzue emails everyone in the city, offering ¥100,000 to everyone who takes pictures of their surroundings and uses all the photos to locate Shigemaru at Oura Wharf.

Kato illegally boards the container ship Shigemaru is on, closely followed by Daisuke in an advanced underwater combat suit.

Suzue scans the vessel and notices the engine is unusually small for such a large ship, so she sends drones after it, narrowly helping them avoid an ambush.

Reaching the engine, Suzue theorizes that Adollium creates energy from seawater and could provide the world with unlimited supply of electricity or be turned into a weapon.

Daisuke’s mother, Sayuri, wanted to broadcast Adollium's existence to the public, so Kikuko had Hattori assassinate her and, for years, has kept Shigemaru prisoner.

The young police finally managed to catch Hattori, armed with the knowledge that the servant had orders not to kill Kato and the critical injuries he still suffered.

Daisuke almost orders Suzue to release the data publicly but hesitates when Kikuko points out that Adollium could be used to create weapons of mass destruction.

Stopping another black market meeting, Kato again falls into the river as an amused Daisuke watches, just like the first time they met.
