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 this 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.

"GGYYYYAAAA!!!!?"

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'?
