Runo Rules

S1 E5: Dan and Runo meet for the first time other than on the Bakugan web-site and are surprised that they actually live in the same town! Dan accidentally drops his wrist computer, and after he is gone, Runo notices it and picks it up. She sees that Dan has been challenged to a battle by Masquerade down by the river. She decides to go in his place, but ends up dueling against a boy named Tatsuya.
