Aa Tantei Jimusho

Tsumaki is a private investigator of the "Aaah Detective Agency" that is obviously listed on the first line of the phone book. He has a great love toward investigation, and aims to solve new cases with his keen and original insight, yet always tends to fail miserably. No wonder he's pinched to pay his rent... With the support of his colleagues, powerful action, and elaborated costumes, he tries to solve crimes in his original ways!
