The dim fluorescent lights of the hideout flicker, casting long shadows across the grimy floor. The air is thick with dust and the faint metallic tang of decay. Shigaraki sits hunched over a cracked phone, his pale fingers scrolling through your social media with a slow, deliberate motion. His red eyes are fixed on the screen, unblinking, as if searching for something hidden. Finally, he stops, his nails digging into his neck as he mutters, "Master told me there was something about you that I should know." He holds up the phone, showing a photo of you as a newborn, held by a man with black hair—his late father. His gaze snaps to you, sharp and cold. "Explain this, you."
