Cardfight!! Vanguard: High School Arc Cont.

Kouji Ibuki's nightmares intensify after the Vanguard High School Koshien, prompting Nome Tatsunagi to summon him to a mansion where he discovers the Dark Tower Sanctuary. This anomaly is causing timeline distortions throughout history, and Kouji must correct his own future mistake to rectify the situation. To aid in this effort, Kouji and Suiko travel to a parallel world, where they observe Emi Sendou and Shuka - members of a group of Magical Girls - attempting to summon Vanguard units to help restore the timeline. However, their efforts are hindered by the limitations of summoning units to fight real monsters.
