Sloth:  "My brain is shaaaaking!” Different eyes, different face, different voice—even so, they shared the same madness-filled look. Though a different being with a different appearance, this Sloth was obsessed with Wilhelm just the same.

Wilhelm:  As he received the repulsive praise, Wilhelm moved farther from the battlefield, pursuing the Archbishop of the Seven Deadly Sins on his own. Given the current balance of forces, he was the only one who could take the madman on. He was the only one who could keep the damage to a minimum and strike the man down. Wilhelm glared at the insane man before him, increasing the speed of his steps.

Sloth:  Heedless of the shower of dirt, Sloth recklessly repeated the invisible attacks. It was as if not only was he insane, but his tactics were stupid, as well. Of course, the duel would be settled just as stupidly. “—!—!!—! !” The madman made some kind of lament, but Wilhelm, running straight forward, did not hear.

Wilhelm:  He stripped away all that was unnecessary, charging forward as he became a single blade, the steel that would rend wickedness asunder. Naturally, as he drew closer the obstacles increased. The number of grazes grew greater, and the inside of Wilhelm’s body was bathed in sharp heat as he poised his sword, lashing out. The earth split apart, and the madman’s posture tilted. Wilhelm turned his sword tip toward the center of the body’s mass, driving it home. “—I have you!” There was not even slight resistance to the tip of his blade. The feeling of rending a life was one the Sword Devil had oft tasted. His treasured sword impaled the madman through the left of his chest, completely destroying the beating heart within. Not even Ferris could have pulled him back from the brink of death. The merciless strike had brought his life to a conclusion.

Sloth:  “…Yes, if it was you, then…” Failing to die instantly with the blade running through his back, the madman spewed blood as he tried to say something.

Wilhelm:  Wilhelm drew his sword back to cut his last words and testament short.

Sloth:  “When you focus on fighting invisible arms, you lose sight of what you can see… Lazy, is it not?”

Wilhelm:  His thoughts contorted for a second. An unnecessary crack in the Sword Devil’s belligerence was pried open, as if he was trying to think of what the words could mean.

Sloth:  An instant later, the madman lunged at Wilhelm, his shaking arm raising a dagger. Then, without hesitation, he employed the dagger to stab his own left eye. Through the eye socket, the tip of the blade invaded his skull, piercing his brain and cutting short his own life.
