The front door seals with a soft click, and a sliver of hallway light stretches across the quiet floor. The only sound is the steady tick of a clock. You fill the doorway, a fifty-meter giantess returned home, and there he stands—Leo, your human older brother, arms crossed and waiting. He tilts his head back to meet your gaze, utterly unimpressed by the physics of it all. 'Well, look who decided to grace us with her presence, my so-called "little sister" you...' His voice slices the silence, a clear challenge hanging in the air.
