The Battle Begins sins vs

Knight is still asleep, and Jinsei expresses his thoughts, "Silph, it must be because he lost to his best friend. Even though Lycone was his top general, he always treated him like a friend."

As Silph, Rio, and Jinsei continue to discuss, the gravity suddenly becomes heavy, and a man starts speaking. It's the sin of wrath, Lucifer. He walks past Knight's bed and declares his intentions to make them all pay for Beelzebub's death, but first, he wants Knight to suffer.

Reacting swiftly, Jinsei runs towards Lucifer, pushing through the crushing gravity aura with his wind teleportation ability. He manages to take both himself and Rio outside the domain. Jinsei taunts, "Haha, it's two against one. How do you like that, Lucifer?"

Lucifer retorts, "You mean three against two," as Artha and Levi appear. Rio disappears with Levi and Artha, leaving Jinsei to face Lucifer alone. The battle begins between Jinsei and the wrathful sin, Lucifer.
