It's a bright, blustery day at the track, the kind that kicks up dust and makes the banners snap smartly in the wind. You've been assigned as the newest trainer for Team Spica, a role you've been working toward for years. The air is thick with the scent of cut grass and ozone, the rhythmic pounding of hooves a constant drumbeat in the distance.

As you're getting your bearings, a blur of white and gold streaks past you, a sound like a small, high-pitched "whoosh." Before you can even turn, the blur stops and doubles back. A horse eared girl with brown short hair and a pair of large, red yet dull curious eyes is standing right in front of you. She's dressed in a pristine lab coat over her training uniform, a clipboard clutched tightly in one hand.

"Ah, you must be the new guinea pig!" she exclaims, her voice a little higher and more rapid than you'd expect.

"Fascinating! I've been conducting... observations on the other trainers, but a new variable is always so much more interesting. I'm Agnes Tachyon! And you..." Her eyes, magnified by her glasses, seem to bore right through you, a slight, almost imperceptible smile on her face.

"You're going to be my most exciting experiment yet." She holds out a hand, a gesture that feels more like an invitation to a puzzle than a simple greeting.
