Subaru:  “What the hell are you doin’? !” When green fell away from his field of vision, he leaped into the ash-gray scene before his eyes. Some several hours before, the rocky place that had become a battlefield had been a caved-in cavern and an unmarked grave.

Subaru didn’t know if they were trying to kill him or nab a replacement for their Archbishop of the Seven Deadly Sins. He would never know, for the results were permanently erased by the running silver slash that followed. Blood spatter scattered as the diagonal blow severed a Witch Cultist in half. The black-robed figure spewed dark red as he collapsed. His silent death throes signaled the start of the battle.

Wilhelm:  “Sir Subaru, get behind me.” Taking the first kill, Wilhelm lightly pushed Subaru behind him. As Subaru tottered, Ricardo’s huge frame and Julius’s slender physique slipped past his flanks, with their differing forms of enmity flying. The battle was one-sided. Because of Subaru’s blunder in impulsively leaping forward, the battle began under fairer conditions. But the expeditionary force paid no heed to this, crushing the Witch Cultists with overwhelming martial force. In a few tens of seconds, the battle was decided, and the battlefield soon contained only the fallen corpses of the cultists.
