From ADV:
An after-school trip to Shibuya turns into one firecracker of a party when Akira, Riki, Shigeru, and Kazuya get struck by lightning - and branded with strange marks on their bodies! To make matters more bizarre, a costumed girl named Syrui demands that the boys return the "God Beasts" that have fallen from the "Gate." When the boys discover these God Beasts came through the lightning, their lives will change. Will Akira and his gang be able to survive their wrath?
