The fluctuations chased and caught up with the vague afterimage, and were then absorbed.
In the wilderness, this kind of fluctuation was not obvious. Sometimes, in the borders where Evil Spirits thronged and darkness creatures clustered, that dark human silhouette did not dodge or avoid, cutting a straight line across their path.
Wherever it passed, the vibrant colors withered into a pale deathly hue, and hordes of monsters lost their vitality, collapsing onto the ground, twitching. And waves of semi-translucent life ripples rose and transmitted, actually forming a visible air tsunami, distorting the field of view as it overwhelmed everything.
Finally, it formed a huge vortex beside Casio, being absorbed.
Slaughter, was always such a simple matter.
Even, there was no need to move a finger, mere proximity meant death!
Casio became a domain of death, greedily devouring all life. Falling into this devil's vortex, no monster could struggle free.
