The moment Acqua roared, he stomped onto the ceiling and quickly descended upon her. Having already been damaged beyond its limits, the fake sky was completely destroyed with this final blow, and the blue silhouette above them became the darkest of blacks once again.

A vertical drop.

A giant mace bore down.

What followed was not a strike, a stab, a shot, an explosion, a break, a split, or even simply a crushing blow.

It was just ordinary pressure.

The sudden charge from above had more than enough destructive power to shatter everything in its path, giving the impression of an asteroid crashing into the Earth.

The world vanished.

Even the sight and sound of the Earth buckling from beneath disappeared.

With the harbinger of this unstoppable blow at the center, everything within a one-hundred meter radius of the fourth level of Academy City's District 22 collapsed. Acqua's falling impact caused the steel and concrete floor to collapse into dust and leave a massive hole in its wake, a floor with the same hardness as those used in safety shelters.

The world around them collapsed, everything within one-hundred meters falling to the 5th level.

The booms and tremors and dust exploded and scattered everywhere.

The sound of destruction echoed throughout the area.

The water streams and turbine generator were cut off, and the water began to flow downward like a waterfall.

Amidst the shattered aftermath, Kanzaki Kaori lay where she had fallen to the ground.

She had blocked the attack itself using the Shichiten Shichitou, but the ground beneath her feet was ill-suited to withstanding such impact.

Having endured such an unstoppable pressure and falling more than twenty meters, Kanzaki lay atop a pile of concrete, looking up.

She was thoroughly covered in wounds, and even though it was not a direct hit, the force of Acqua's most recent blow corroded her body through her weapon. Trapped between the massive mace in Acqua's hands and the artificial ground beneath her, regardless of whether it was her arms, legs, or torso, a reddish-black liquid gushed out of Kanzaki's body.
