4x1 - Yu-Gi-Oh! 5D's

Sherry tries to get answers concerning the card her parents were killed over (which is the Z-ONE spell card). She decides the best way to figure it out is to use the Public Security Maintenance Bureau's super computer. The next day, Sherry and Elsworth set off a dummy bomb at HQ, causing everyone to evacuate. When they lock the building down, Yusei and Bruno are left inside, and they soon discover the two. As Bruno follows after Sherry, Elsworth blocks Yusei off, and challenges him to a duel. Elsworth summons his Driven Daredevil, which does great damage to Yusei during his counterattack. Sherry reaches the main computer, hoping to find out the meaning behind her card, but starts fighting Bruno when he shows up. Just then, Bruno's eyes start glowing red and he overpowers Sherry. Noticing her card, he stops attacking and helps her to analyze it. Yusei summons Stardust Dragon and beats Elsworth with a counter trap, and the two catch up to Sherry and Bruno.
