Detectives These Days Are Crazy
Mattaku Saikin no Tantei Tokitara

Once, there was a renowned detective named Keiichiro Nagumo, who was the talk of the town. He solved numerous cases with great skill. Now, however, he is a retired detective. He is rooted in traditional methods, and perhaps due to his age, he is grappling with a deteriorating body while still pursuing his work as a detective. Amidst this, a high school girl named Mashiro approached him, seeking to be his assistant. After some negotiation, he ultimately accepted Mashiro as his assistant, marking the beginning of their dynamic daily life together.
