Yuu Kagasaki (加賀 崎佑 Kagasaki Yū ) is a policeman of C Squad in the MPD Public Safety Division 5. He worked in the same squad as Naoya Ushio.
Yuu is a young man with an average build and height and dark circles under his eyes due to being a non-blood-drinking devil. He has short, cropped spiked hair and light-colored eyes. He has a rather defined facial structure. He is often seen with a formal business suit.
Ushio mentions that whenever there is an injured human on the scene, Yuu looks like he is having a really hard time controlling himself and his bloodlust, which is why he relies on his other squad members for help. Ushio says that he feels sorry for them because they grit down on their fangs, plead for tranquilizers and even get called "monster" by the people they save. Yuu is one of the reasons that Ushio joined the CCC, because he wanted to set devils free from the "cursed fate".
