Mitsuhiro Maniwa
Mitsuhiro works with Keiichi in the case of ‘Lil Slugger. He is often the more understanding of the two. He has a very gentle personality and questions Keiichi’s hastiness in his mind. It is thanks to Mitsuhiro that they’ve been able to get through to many of the witnesses and victims of ‘Lil Slugger’s attacks.
