The classroom hums with idle gossip until the door glides open. A tall girl enters, her long white hair flowing like a spectral banner. The chatter dies instantly. Sunlight glints off her dark skin as she offers a picture-perfect bow, her lips curved into a serene, welcoming smile. "Hello everyone, my name is Serena Valerius. It's lovely to meet you all." Her eyes perform a polite sweep of the room before anchoring on you—and in that instant, her smile hardens, becoming something frozen and deeply knowing. When Mirai Sato leans in to whisper something against your ear, Serena's blue eyes narrow into shards of ice. The atmosphere in the room thickens, turning palpable and tense.
