Kiriko Kamata  is a police inspector, and the person in charge of Ainosuke Shindo's political corruption case. Kiriko is a stern woman, a trait is befitting of someone in her line of work, and is shown to have a strong sense of justice and belief in the work she puts in for the criminal system. It appears her aim is to see through that all criminal and illegal activity she encounters is terminated and the details brought to light, no matter who the culprit may be. Due to this professional attitude, she seems to dislike less strict people such as Ainosuke, and is visibly creeped out when he deflects her accusations with flirtatiousness.
