Scaling Saint Killer Acqua

Kanzaki attempted to stand up, but no strength would enter her legs. There were special circumstances in that situation, but even so, that was the most ridiculous enemy she had ever faced. She had previously fought an imperfectly manifested version of the Archangel Gabriel and Acqua of the Back who used that angel as a symbol, but she had at least been able to “fight” against them. But with Knight Leader she couldn’t even do that. And he did not even take pride in his strength. “So you haven’t given up yet,” said Knight Leader narrowing his eyes out of disinterest. “In any case, a mere Saint cannot kill me with their special strength.” As Kanzaki attempted to muster some more strength, Knight Leader casually approached her directly from the front. As he did, he spoke. “And I haven’t even drawn my sword yet.” He kicked Kanzaki. It was not the kick of a martial artist. It was much like he was kicking a soccer ball. Kanzaki’s body flew through the air and then rolled along the ground. Knight Leader didn’t even look over in her direction and instead gestured at his subordinates. They all boarded carriages or mounted horses and headed in the direction the second princess had disappeared in. Atop his horse, Knight Leader looked in Kanzaki’s direction for just an instant. Seeing that she had completely lost consciousness, he spoke disinterestedly. “So that’s all a Saint can do.”

William Orwell. Seeing the large man come running to save Third Princess Villian with the spiritual item known as Ascalon in hand, Second Princess Carissa smiled thinly. That man annoyed her greatly because he was uninfluenced by the various organizations and he would unhesitatingly destroy the carefully laid out plans of even the Royal Family because it was “for England”. She had a thought while everyone was left speechless at the appearance of that mercenary. (Ascalon? A sacred sword spiritual item made according to the legend of St. George?) Carissa knew that man was naturally skilled with water and that he had to be overwhelmingly powerful due to his strength from his mercenary days being furthered evolved as a member of God’s Right Seat. (Why did he need to prepare something like that? Folkestone is a port city and a mountain with a water source that isn’t far away. The water he is so skilled with should be all over the place, so why is he relying on such an obvious weapon like Ascalon?) She also knew the reason the mercenary was not using water. A pipeline still existed between England and Academy City. As such, they had received information that the man known as Acqua of the Back who had control of the power of Gabriel had attacked Academy City and had been defeated. (He’s wounded meaning he can’t control water. That’s why he has to rely on a spiritual item as over the top as Ascalon. If he’s lost some of his power leaving him at the level of a mere Saint, Knight Leader is enough to deal with him. And Knight Leader’s power isn’t just theoretical. He has been tested in his fight against the Saint from the Far East.) Having checked the information she already had with the information she was currently gathering with her own eyes, Carissa smiled. She came up with an overall conclusion. (Right now, we can kill him. We can kill that annoying mercenary.)

“Even though our strength has been augmented with Curtana’s power to a certain extent, not many of us have reached your level.”

“Since you aren’t using that water of yours and you aren’t carrying out that sliding high speed of yours, your defeat in Academy City must truly have had a lasting effect on you.” William did not respond.

“That was fast,” praised Knight Leader. “But it’s too bad. Just once, I wish I could have fought you at your peak.”
