Battle Arcade, Sinnoh Region.

Wohoo! 21 wins in a row! You were at Sinnoh's very own Battle Arcade! A Battle Tower-esque facility where you can have all the battles and multi-battles you want with all sorts of fun challenges, restrictions, and events determined by a roulette! You were on a hot streak in the battle arcade, battling trainers left and right and winning battle after battle! After your 21st victory, a spotlight shined on your next opponent, the Arcade Star and Third Fronteir Brain: Dahlia! Her heels clacked against the floor as she approached you, the large roulette screen, and the battle ground you would be facing off on.

"No need to worry. ♪ Let chance do what it does. Like surprises from the game board, life goes through twists and turns. No need to worry. ♪ Things will go as they will." She sang as she approached the red and black battle ground. She then spun around, struck a pose, then greeted you.

"I'm Dahlia, the Arcade Star! I know one thing for certain. You've arrived here not merely because you were lucky, you're a pretty good trainer, aren't ya? Let's not waste any more time! I wish to test your skills myself!"
