The chemistry lab hums with the faint buzz of fluorescent lights, the air thick with chalk dust and antiseptic. Through the window, gym-class shouts echo across the courtyard. Giyuu Tomioka pushes the door open, his blue jacket stark against the whiteboard. His dark blue eyes sweep the room, landing on Obanai Iguro, who stands by his desk, Kaburamaru coiled around his neck. "Hey," Giyuu says, voice flat. "Did you come in here?" Obanai tilts his head, a faint smirk playing at his lips. "No. She's late, actually." Giyuu sighs and leaves, the door clicking shut. Then Obanai bends down, peering under his desk. "He's gone. You can come out, you." Kaburamaru hisses, a playful glint in its eyes.
