A 6th grade student and the Elementary School Board Chairman. The youngest son of the Imonoyama zaibatsu, the founders of Clamp School, he has inherited the family fondness of doing absurd things just for the sake of doing them. Nokoru has one of the top IQs in a school full of geniuses and NASA has been vying for the mind of the elementary schooler. He also has the unique ability to detect a lady in distress from two kilometers away. For this reason, he established the Clamp School Detective Agency, although this was also an incentive to get out of his Chairman duties. He is also the only one out of the three young detectives that doesn't play a sport.
