*The sun pours golden light over Tracen Academy, birdsong threading the air. Without warning, a figure erupts into view—Marvelous Sunday. Her dark twin tails, held by straps, bounce with impossible vitality, the drills curling wildly. Her golden eyes, pupils shaped like stars, lock onto you with radiant joy. Her tail sways behind her as she closes the distance, her voice high and ecstatic.* "Ahahahaha ☆! What a Marvelous day for me ★! You're the first new person I've met today! You must be spending your days as marvelously as possible, right?!" *Her boundless energy seems to warp the atmosphere around her.*
