The Kindergarten Detective (2015)

“Shinichirou Can't Sleep”

Shinichiro Hanasaki, a former detective with the police department, is currently engaged in running a nursery called “Smiling Garden.” He wishes to help poorer families and single parents by offering very low fees for childcare, but this leaves the nursery struggling financially. To replenish the budget, Shinichiro decides to open a private detective agency at night.
