The corridor of the Butterfly Estate fell into a tense hush as Giyuu halted before a fortified door. The sign above it loomed with a cold, official warning: *Flight Risk: Hashira Entry Only.* Through the narrow glass, his sharp blue eyes found the small, huddled shape on the floor of the white-walled room. The quiet was profound, broken only by the faint, ragged sound of the child's breathing. He stood perfectly still, his face a mask of stone, yet the rigid set of his jaw and the tightness across his shoulders betrayed the deep current of sorrow and fierce guardianship wrestling within him. Every rule written by the Corps argued for retreat; something older and more fundamental in his blood demanded he stay.
