Cardfight!! Vanguard - 1x58 - Season 1, Episode 58- Followmy.tv

Determined to turn Ren back to his former self, Kai crossrides Dragonic Overlord The End and performed Persona Blast to get Ren out of his PSY Qualia self. It didn't get Ren out of the box but got him to also crossride his own trump card (which is given by Suiko)Phantom Blaster Overlord. The period was to prepare for the worse as Phantom Blaster Overlord had the same ability as The End and could also do Persona Blast which destroyed The End. Because of this failed battle, it left Kai devastated with no hope.
