Y/N has moved to Kuoh Town with his uncle to start his new life at Kuoh Academy. Y/N has a strange dream of being King when he grows up because of that dream he was bullied and made fun of at his old school.
Even with the bullying Y/N still smiled...
A broken Y/N is on his knees looking at where Asia used to be.
Issei: "Asia?"
Xenovia: "Why?"
Gasper: "Asia-senpai!"
Koneko: "Why?"
Voice: "Enough playing around, Diodora Astaroth."
Rias: "Who's there!?" A green magic circle appears for a man to teleport in the room floating near the ceiling.

Man: "The despicable, fake Satan's little sister. I am the descendant of the original Beelzubub, Shalba Beelzubub."
Rias: "Beelzubub." Runeas and Kuroka are checking on Y/N.
Kuroka: "Y/N! Stand up! Another enemy has showed up!"
Diodora: "Shalba! Lend me your hand. If both the old and current Satans combine their strength...." A light blast hits Diodora's stomach to leave a giant hole.
Shalba: "Fool." Shalba gestures his arm for a beam of light to fall down on Diodora to disintegrate him.
Shalba: "Old Satan? Calling the old bloodline "old" is a mistake in itself. Now Aevi, Diodora was a fool but you betraying me will not be forgiven." Shalba fires another light blast but Aevi stops time.
Aevi: "You're old bloodline will fall." Aevi snaps his fingers for the light blast to be dissolved and he disappears.
Rias: "Shalba! You were behind the death of the Glasya-Labolas heir, weren't you!?" Rias starts to glow red.
Shalba: "Starting to claim oneself a Satan in sheer ignorance."
Outside in the battle against the Khaos Brigade, a devil is facing Azazel.
Devil: "I am the true descendant of Asmodeus, Creuserey Asmodeus."
Azazel: "So one of the great masterminds finally shows yourself."
Creuserey: "As a member of the True Satan Faction I will avenge Katarea Leviathan. Using the power received from Ophis, we will destroy this world and create a new world for devils!" Creuserey holds his hand out for an infinity magic circle to appear in his palm.
Rias: "I will never forgive your crime of killing Asia!"
Shalba: "Sirzechs' little sister, I will have you die as well." Shalba holds his hand up for the same infinity circle to appear in his palm. Mikoto grabs Y/N by the shoulders.
Mikoto: "Y/N! Get up or you will lose another one of your friends!" Shinnosuke stands in front of Rias to turn the key on Mr. Belt.
Shinnosuke: "I won't let you take another life!" He holds up the Shift Tridoron to activate it.
