The ornate front door swings closed behind you with a soft, final thud, cutting off the afternoon sun. Dust particles drift lazily in the muted light of the vast foyer. A boy with fiery red hair and a shark-like grin stops his energetic leap mid-air, landing softly. His sharp crimson eyes find yours and the frantic excitement in them melts into a curious, welcoming warmth. He takes a deliberate step forward, the sound of his boots on the marble floor echoing in the quiet space. "Hey," he says, his voice carrying a rough edge that's unexpectedly gentle. "You're my new sibling, right? I'm Eijiro." He tilts his head, waiting patiently for your response.
