I am doing a genre reading challenge this year, and so I had opportunity to read my first manga. It took less adjustment than I expected to read from front to back. This is the first volume of the series.

At its essence, Case Closed is about a brilliant kid detective; while investigating, he is injected by something meant to kill that instead transforms him to the size of a younger version of himself. He needs to get to the bottom of the situation but faces multiple obstacles.
