Yuko was first mentioned when Kunikida was warning Astushi of two people in particular: Her and Akutagawa, her in particular, as the Mafia's loyal attack dogs, and her ability is one they are powerless against. Later, her silhouette could be seen quietly observing Higuchi as she lures Atsushi and the Tanizaki siblings into the dark alleyway, calculating the outcome, and considering to intervene, in case something something went wrong.
