Scaling Acqua to Kanzaki

Each wing was thoroughly infused with the Power of God, and each attack could flatten mountains and carve valleys like Divine Judgment. Even if it was on the battlefield as per normal, Kanzaki, who often caused enemies to back away in fear, was now stiff with tension. If it were anyone else, the killing intent released would have caused the person to faint.
(Toaru Majutsu no Index Volume 4, pg 152)

The water wings that were infused with Telesma from tip to tip could each send out a Judgment that could wreck a city. Once it sent that, this beach would vanish completely, forming a crate like cover, like how in legend, God shaped the earth.

Such a scene gave a look that a tower was collapsing. The air that was ripped became a fist of air as it scattered about, until the wind itself collapsed due to the water wing. The water wing came swinging down at Kanzaki Kaori with shocking speed. It was all over. Everything should have been over. BAM! With a clear sound, the water wing was sliced in half by a horizontal flash. Who could have predicted such a scene? Power of God was stunned, and Kanzaki merely took a deep breath in response. The over two-meter-long nodachi that was hanging from Kanzaki Kaori’s waist. The moment she drew the sword, the seventy-meter-long water wing was sliced easily like a bamboo tube. Also, the remains of the sliced water wing immediately scattered into powder like an explosion and vanished into the darkness of the night sky.

“Yes, yes! Because the Priestess is one of the Saints, and there are less than twenty of them! No matter what, we only need the Priestess to finish them off in one hit!” “Hm, is that so,” Kamijou suitably replied to Itsuwa. “Well, since she could fight against an archangel like Power of God, she is truly strong, that Kanzaki.”

Kanzaki let out a loud cry as she used a battojutsu technique. Using the idea of manipulating other teachings to counter a specific religion and cause damage to the opponent, even the angels in a monotheistic religion could be sliced in half. This was Kanzaki’s killer move. If Christian spells were ineffective, she would use Buddhist spells. If Buddhist spells were ineffective, she would use Shinto spells. If Shinto spells were ineffective, she would use Christian spells. Using such a method to mask the weaknesses of other religions, a one-of-a-kind spell filled with destructive power. Yuisen. No matter how great the numbers or how strong the person, no one should be able to survive it. Acqua’s huge mace blocked the strike and, after trading a few hits, it was clear to Kanzaki that Acqua likely knew as many spells as she did, possibly even more. Since Acqua was not an ordinary member of God’s Right Seat, he was even able to cast ordinary magic spells.

Acqua of the Back’s mace was ringing. It was not like it was some special nor some spiritual item, it was just purely human effort. The moment Kanzaki used her special spell called Yuisen, her power would momentarily increase. But against Acqua, she didn’t know when she would reach her limit. With this, the difference between the two increased, and finally—she reached her limit. An explosion. As Kanzaki used her Shichiten Shichitou to receive the mace, her whole body was sent flying backwards. “Gyyyaaaaahhhhhhhhhhhhhhhhhh!?” Having battled continuously, Kanzaki’s body looked like it was about to crush the hill of rubble as it flew away for a hundred meters without bouncing back. Her body became a cannonball as it destroyed every single hill of rubble and turned every single scrap of concrete into dust. “Is this the end, Saint of the Far East?” The feeling hidden within Acqua’s words was disappointment. But after being buried inside the rubble, Kanzaki was unable to even move her body, let alone respond to him. The strength she had now wasn’t even half of the amount that shot up her blood. (...Is there anything...) No such things as petty tricks or tactics. How should she battle with that man when there was such a disparity in power? (...What’s the real form of...that power...?) Kanzaki spat out some blood as she wondered. Having used all the power in the body of a Saint to use her Yuisen, Kanzaki understood that a Saint’s attributes far exceeded what a human could do. Yuisen had originally been created as a one-strike sword technique. If she didn’t do it like this, she may end up destroying her own body. But Acqua broke through this impossible possibility front up. Thus, he could pull the distance between himself and Kanzaki.
