Honma Kai and Ichinose Jiro are cadets at the police academy. Honma is the intellectual type who places emphasis on theory. A serious A-student born with excellent memory, he developed analytical skills at the academy and his skills at profiling began to blossom. He might seem like he does not care but he will not give up on people in need. On the other hand, Ichinose is the emotional and physical type. He is a fearless fighter whom even people with martial arts experience will dodge because of his boundless physical strength. Although his somewhat goofy way of speaking and thinking confuses the people around him, he is an honest, kind-hearted guy who will be the first to help when anyone who is in trouble. What the two of them lack practical experience, they make up with the knowledge obtained through lessons at the academy as well as their youth and enthusiasm. They become the best buddies who make up for each other’s deficiencies.
