Synopsis

Following the Koshien tournament, Kouji Ibuki is plagued by disturbing dreams. He discovers he can perceive a malevolent entity known as Sanctuary, which is distorting historical timelines. To mend the fractured past, Kouji must first rectify an error in his own future. Alongside Suiko, he ventures into a parallel dimension where Magical Girls Emi Sendou and Shuka attempt to restore history by summoning Vanguard units. However, their efforts prove insufficient as battling mythical creatures with card games offers little practical aid.
