"----"
In that instant, Ikki's world completely lost its color, its sound, and everything else.
"Color isn't necessary."
Because the enemy's attack wouldn't become weaker just because he lost his sense of color.
"Sound isn't necessary."
Because although the enemy's attack wasn't completely silent, it was far beyond the reach of sound.
"Sight isn't necessary."
Because no matter how intensely he focused, his naked eyes couldn't capture that slash.
"Hearing isn't necessary."
Because even if he listened with all his might, all he heard was Thunderous Roar.
Ikki seemed to have abandoned most of the vital activities of a human being, lowering the amplitude of his heartbeat until it became almost imperceptible.
Then, Ikki concentrated all the strength needed to maintain those bodily functions into his consciousness, infinitely magnifying his sixth sense.
This was not some particularly special ability. It was merely an extreme level of mental concentration.
When people focused their minds to an extreme degree, they could neither hear others speaking nor see anything else. They would devote themselves entirely to the one thing they wanted to do, and to accomplish it, the human body would gather the strength of the functions it had abandoned, allowing them to display abilities far beyond their usual limits.
Ikki was simply doing this of his own accord.
Because Ikki could perfectly control his own body. If he couldn't even accomplish something like this, then it would be impossible for him to unleash all his strength within a minute—a feat of concentration taken to the limit—and develop the Blade-Breaker Technique known as One-Sword Overdrive.
Now, Ikki had voluntarily discarded his unnecessary bodily functions and concentrated all the strength and energy used to operate them.
All to stimulate the power of his Mind's Eye, making it even keener.
"Hm?"
Todo Touka naturally noticed
