Chasing the Rival

You told me to fight Shadow, so I took off across the hallway floor to track him down. Turns out, the fastest shadow around was actually stretched out right beside me under the morning sun! I charged headfirst into full sprint, darting past table legs and pivoting around sneakers. Every time I leaped, that dark outline matched my pace perfectly on the polished wood. I skidded to a halt, threw a fierce right hook right into the carpet, and... well, missed the darkness entirely. But hey, it was a solid warmup. Nobody outruns me forever!
