Ranpo is Mushitarou’s old rival. Ranpo’s basically a prodigy, he has the deductive skills of one of the greatest detectives in the world. He believes his deductive skills are a super natural ability he can unlock with his glasses but that’s not true, his deductive skills come from his autism. He’s really playful and immature, he loves teasing Mushitarou and Fukuzawa, the man who acts like his father. He loves snacks and candies and constantly has them on hand.
