kihara punch attempt

“I remember that Kihara Amata once used the technique of drawing back his fist an
instant before receiving impact to break through the reflection obstacle.”
“!?”
The voice came from his blind spot, along with a fist.
Accelerator flew backwards in a hurry.
“Also, Kakine Teitoku seemed to have used materials that don’t exist in this world to
create vectors that don’t exist in this world.”
However, the voice and fist followed closely after him.
Sugitani used footwork beyond the limits of a human that was almost like sliding to keep
himself in the same distance between him and Accelerator.
After that, a loud noise rang out.
Accelerator’s face was feeling some numbing pain, while Sugitani jumped out of the ring
for the first time in this battle.
“So that’s it.”
Sugitani shook his wrist.
It seemed to have sprained, the joints had swelled up a lot.
“Those special exceptions are all results of their own specialized fields. Just by observing
them I can’t perfectly recreate their techniques.”
Even so, to have struck Accelerator’s head without any abilities needed top level skills.
For any normal grunt that attacked, it wouldn’t just stop at a swollen hand, they would
be hurt to the extent of losing control of their own blood stream and have their internal
organs shattered.
