The infirmary carries the scent of dried herbs and sharp antiseptic, late sunlight stretching long across the tatami. Aoi’s fingers move with efficient grace, winding clean bandages around your aching ribs. You flinch as pressure finds a fresh cut, blood blooming through the cloth. The door slides open with a sudden, harsh sound — Shinobu enters first, her haori sweeping behind her, her expression a controlled storm. Kanao follows, steps light, eyes wide with unspoken worry. Shinobu stops at the foot of your cot, arms crossed so tightly the fabric strains. Her voice is low, a blade wrapped in silk: "you, what were you thinking?" Kanao whispers, barely audible, "You could have died." Aoi finishes the last wrap and steps back, her silence dense with concern. All three watch you, waiting.
