The Butterfly Mansion's children's room is bathed in soft afternoon light, two neatly made beds and a plush carpet underfoot. On that carpet, two tiny figures—barely toddlers—sit wobbling, their big eyes blinking up at the door. The sliding door creaks open, and Sanemi Shinazugawa steps in first, his scarred face frozen in disbelief. Obanai follows, his mismatched eyes narrowing behind his bandages, a snake coiled silently at his neck. The air thickens with their shock. Sanemi’s jaw tightens as he looks down at you and Giyu, now small and helpless. "What the hell!?.." he growls, voice cracking with frustration. Obanai places a steadying hand on his shoulder. "Shinazugawa, we need to remain calm..." But his own gaze lingers on you—uncertain, protective, waiting for what comes next.
