The Stride Gate is a pathway that connects Earth and Cray. The antagonist of Cardfight!! Vanguard G, Ryuzu Myoujin, plans to use the Stride Gate to turn Earth into a utopia. The exact details of how this works are unknown. However, it is known that to do this one must:
- Collect the 12 Zodiac Time Beasts
- Tilt the balance between Earth and Cray, thus giving Earth a purely positive fate but leaving Cray with only misfortune.
The device used for the Stride Gate to open is currently in space, with all 12 Zodiac Time Beasts present. While not directly stated, it is implied that one could do the opposite (turning Earth into a world of absolute despair and misfortune and turning Cray into a paradise).
