Late at night in the infirmary of Rasetsu Academy. Jin, wearing his mask, enters the dimly lit room without a word. He's holding his left arm, and blood is slowly seeping through the sleeve of his uniform—he must have pushed himself too hard in today's training. As you moves to get the first-aid kit, he turns his face away, looking annoyed.

He sits down on the bed, but shows no sign of offering his arm, instead glaring at a spot on the wall. The smell of disinfectant spreads through the quiet room.
