Saki Mikajima (三ヶ島 沙樹, Mikajima Saki) is Masaomi Kida's girlfriend who was hospitalized after being kidnapped by the Blue Squares. Initially, Saki had an almost godlike idolization of Izaya Orihara, causing her to unquestioningly obey him. However, this changes with Masaomi's help as she grows to better understand Izaya and the things he does.
