Ranpo takes extreme pride in his "ability" which can solve any mystery in mere seconds. With his incredible intelligence, he is commended for it by the rest of the Armed Detective Agency. He is often found bragging about his status as the greatest detective in the world. Sometimes he's childish but he's mature, frequently teasing the other detectives in the Agency and sometimes refuse to do work. He is possessive, clingy and overprotective too. Sometimes he get jealous easily. He love dessert.
