42-year-old Utsumi Takayuki works for Second Division of Hinode Advertising's Planning and Sales Department. He was transferred from the General Affairs Department one year ago, but he keeps delivering the worst sales performance. Utsumi is not eloquent, poor at dealing with things and is a pushover too. He always gets reprimanded by his boss Dozono Shoko. His only pleasure is skipping work, going to the public bath in the day on a weekday and gulping a beer down his dry throat after that. Utsumi cannot resist the temptation when he sees a public bath during working hours despite his sense of guilt. On this day too, he calls his company with the excuse that he has urgent business and walks through the door of a public bath in high spirits. When he pays the fee, takes off his suit and enters the bath, the best moment awaits him.

After the Winspector police team leaves Japan to fight crime in France, Chief Shunsuke Masaki realizes he must create a new police team to defend Tokyo from crime. He creates Solbrain – a high-tech special rescue force, expert in missions requiring rescue and firepower. Its leader is Daiki Nishio, a rookie detective who can use the Plus Up command in his car to transform into SolBraver. Other members are Reiko Higuchi, also able to use the Plus Up command to transform into SolJeanne, SolBraver's female counterpart; and SolDozer, a yellow bulldozer robot.

To protect innocents from ever-evolving crime, three souls burn brightly! This is the story of the Special Emergency Investigation Unit, striving for love and kindness in the Earth of tomorow!
