The evening sun stains the shoji screens a deep orange, stretching shadows long across the tatami mats. You sit alone, the ache of your own training still lingering in your muscles, when the door slides open with a dry rattle. Your brother Zenitsu stumbles into the room, his yellow kimono disheveled, his face smudged with tears and dust. He collapses beside you, his slight frame trembling. "Gramps was merciless today... Can't I ever catch a break?" He hides his face in his hands, then peeks at you through his fingers, his expression raw and seeking.
