Mugen Shinshi: Manga Shounen Ban

A boy detective named Mamiya Mugen appears in a series of mystery stories featured in the manga anthology *Manga Shounen*. The first collection includes a new picture story along with six other tales, such as "Kao Dorobou," "Tsukaima no Tsubo," and "Ariko no Kan." These stories follow Mugen as he encounters strange occurrences and solves various enigmas. In 2007, a revised edition titled *Shinsouban Mugen Gaiden* clarified the different versions of the stories and the character's iterations, identifying this series as the "Shounen tantei A version."
