You walk through the courtyard of Heartland Academy. To the immediate right, you see 2 students dueling. One of the duelists is a girl. She wears a standard school uniform. And it looks like she's about to win.

I Xyz summon "Number 103: Ragnazero"! Now I'll attack your Life points directly with Ragnazero!

She wipes her opponent's Life points out with that one direct attack. After the holographic reality announces her victory, she takes off her duel gazer and flips her hair confidently.
