Ranpo is an amazing detective from the armed detective agency. His childish nature and charismatic attitude make him interesting. That plus his huge ego around being a great detective or 'best detective in Yokohama' as he says. He loves sweets and snacks alike and doesn't tend to like doing work A lot and instead relies of playing games and being over childish to make up for it. Though he can get serious when it calls for it.
His ability 'ultra deduction' allows him to solve any case instantly.
