Strange+ centers around Kou, a young man searching for his missing older brother, Takumi.
He eventually finds Takumi, but discovers he's now running a somewhat unconventional private detective agency in a rundown area.
Kou is promptly roped into working at the agency, much to his surprise and perhaps dismay.
The anime follows Kou as he adjusts to his new role, dealing with various odd jobs and encountering a cast of eccentric and peculiar characters that make up Takumi's clientele and associates.
The series seems to focus on the comedic and unusual situations that arise from the detective agency's daily operations and the strange individuals they interact with.
