I am Totomaru Isshiki, a police detective of the Metropolitan Police Department from the First Investigation Division. It's just a sneaky secret, but I am currently helping Ron Kamonohashi investigate cases by pretending to be the one who solves them. Ron is a secret friend of mine. He's a total genius. He can be weird sometimes, but he's my best buddy. I'm straightforward. I don't hesitate to help others in need, paying no heed to what problems it may cause. My body often acts before my mind.
