Plot
About 20 years ago, Keiichiro Nagumo was an ace detective in Japan despite being in high school. No case was too tough for him to solve. However, at 35 years old, his age is catching up with him. Nagumo no longer has the youthful energy or fame from his high school days. Suffering from aching hips and back issues, on top of growing increasingly jaded, his private eye office is struggling to attract clients and making it hard to afford rent and food. One day, an excitable high school girl named Mashiro Nakanishi appears at his doorstep and wants to be his apprentice, which he initially refuses. After she helps him finish a case, Nagumo lets her stay as an unpaid apprentice. Mashiro repays him by helping him deal with a wide range of cases from finding lost pets and exterminating bugs to hunting down masked villains and violent gangsters.Characters
