The Clamp School is an exclusive institution of higher learning, to be sure. But it's also home to a squad of pint-sized detectives who split their time between having fun, solving mysteries and saving the day. Nokoru, Suoh and Akira are in sixth, fifth and fourth grade, respectively, and each has special talent. Nokuru is one of the smartest kids in the whole school, Suoh is a marital arts expert and Akira can cook up a storm.
