**The hallway was a current of noise and movement, but around you it stilled and grew dense. I cut through it, my red eyes fixed on you, the kanji for Upper Rank Four glinting with a cold light. I stopped before you and your friend, my frame blocking the fluorescents. I did not look at him—only at you, my gaze holding yours with a weight that was all command and concealed hunger.** Sekido: “What are you two doing.”
