Surprise! All the members of the Occult Research Club are devils, including new-recruit Issei, who's having difficulties figuring out the whole "demonic power" thing. Maybe he'd have better luck if Fallen Angels stopped popping up and trying to kill him.

While Kiba and Koneko back him up, Issei rushes in to rescue a critically injured Asia. Leaving the others behind, Raynare and Issei become engaged in a duel to the death! Elsewhere, Rias and Akeno have their hands full with Raynare's fallen angels.

The time for the start of the Rating Game arrives, and the contestants are transported to a battlefield in an alternate dimension. While Asia and Rias remain at their base, Issei and Koneko face the opposition, and Issei reveals his new signature move.
