Editing Shinmai Maou no Keiyakusha:Volume 7 Chapter 4 (section)

===Part 1===
The ancient city of Lada that the third generation Demon Lord Lezonas ruled.

Within the artificial space that emulated what was once the royal city recorded as a turning point in history, a particular sound continued to ring out unerringly. They were the continuous sharp sounds of clashing blades, and from time to time, intense vibrations from impacts made in the air. These sounds alone were able to describe just how fierce the battle was. The source of the sounds were not set in one place, they didn’t stop moving for even a moment. At the source of the sound — there were two silhouettes leaping between the rooftops of the historic buildings, and like two gales of wind crossing each other, they clashed successively in mid-air. One of them was a human youth who wielded a silver demonic sword, while the other one was a demon youth who swung a jet-black demonic sword — Toujou Basara and the Current Demon Lord Leohart. After the two of them clashed at full-force with their first hit, they then made full use of the entire space for their high-speed battle.

''…Truly fast.''

Even though Leohart’s speed had similarly increased to such a degree that he seemed to have become one with the wind, he still appeared to be amazed at the speed of his opponent. In terms of pure strength and swordsmanship, Leohart was clearly superior, but Basara who was darting in front of him was significantly faster. Leohart had fought against many Heroes in the previous Great War, and he had also witnessed many of his powerful comrades such as Balthier, Lars, and the Eight Demon Generals; but to be honest, he couldn’t remember if any of them could achieve such speed. In Gardo’s report, he mentioned that Basara was faster than him at his best, but—

''…It can’t be wrong.''

The current Basara was definitely much faster than when he fought against Gardo. Gardo’s power in that state was indeed amazing, but his speed was still below that of Leohart’s; moreover, Leohart was chasing after Basara’s afterimage at the moment, and he could barely keep up. However, Basara with his speed advantage was no longer keeping his distance from Leohart. Basara was no longer leaping and accelerating from the many rooftops present, while Leohart used his leg strength to maintain his speed, prepared to leap at any time. Basara twisted his body in mid-air, turned his legs to change direction, and faced Leohart who was chasing him from the rooftops behind. After tearing through many red tiles as he skidded, he suddenly charged straight towards Leohart.

“……!”

Leohart prepared to swing towards the ground in a single strike. The purpose of that was not to defend against Basara’s sword that was aimed towards the upper right, but to repel him with force. Then, just as the sound of their colliding swords rang out, Leohart used the contact point and pressure of their blades as support to jump up directly over Basara’s head; and after a mid-air somersault, he chose to land on an adjacent rooftop…but he didn’t descend immediately, and instead performed a horizontal slash behind himself beforehand. The sound of metal pushing against metal was heard in the next instant. After Basara saw Leohart jump up, he immediately turned around for another strike, and that was why Leohart was forced to react. In the instant that he finally landed, the battle had turned into a close-quarters sword duel in which he had no chance to rest.  Within Leohart’s entire range of movement, Basara began a non-stop high-speed onslaught, while Leohart remained fixed to the spot as he defended. The sound of clashing blades was heard a countless number of times from every direction, and gradually surrounded him. It was not long after the fierce slashing sounds began that a particular phenomenon occurred before Leohart’s eyes. The wielder of the sword, Basara, appeared to multiply.

“This is…”

It was the critical phenomenon that had occurred as a result of high-speed movement at a close distance. Afterimages of Toujou Basara had appeared in front of Leohart’s eyes.
