Kazuko Suema

Kazuko Suema is a Shinyo Academy student and a trusted friend to both Nagi Kirima and Toka Miyashita. While urban legends hold little appeal for her, she harbors a profound fascination with criminal psychology and deviant human behavior. After being personally caught up in a series of murders, she resolved to pursue the truth through reason and evidence rather than superstition. Though she possesses no extraordinary powers, her exceptional observational skills and analytical mindset make her an indispensable figure—one who approaches the heart of each incident from a grounded, human perspective.
