Kaga Kyouichirou, who has a knack for reading a person's mind, has just been transferred to the Nihonbashi police department and is put in charge of a murder case that occurred at Ningyocho. There, he uses his insight and observational skills to solve the case and others that come later.
Both are about crimes; the investigator is a newcomer. He is very good at discovering people's lies and can read their minds due to their movements or habits, noticing their movements and everyday behavior. He himself likes to behave strangely at times and tease his stupider partner.The OST of both is by the composer Kanno Yuugo.
