accel magic song

He would be swallowed up by the mysterious laws.
Accelerator knew that, but he did not stop. He continued on. He shot down the slope in
a straight line. He could already see the edge of the cliff. Accelerator saw that deep hole
as a gate. He unhesitatingly headed forward and leapt into the bottomless darkness.
He crossed that line in an instant.
Immediately afterwards, a change occurred.
“...!!!???”
With a cracking noise, something within his body let out a cry. The blood vessels on the
back of his hand swelled up oddly. He became strongly aware that he had thick blood
pipelines running from his fingertips to his shoulders. As soon as he noticed that,
something tore. His skin ripped from the inside and a dark-red liquid squirted out.
Had he realized it?
By breathing in a way impossible for a normal person and using vibrations from his
entire body rather than just his throat, he had let out an extremely special voice. With
that voice, he was refining his life force into magic power, putting together a spell, and
outputting it into the real world. In other words, he was using true magic.
Espers could not use magic.
If they forcibly used it, what awaited them was an enormous rejection reaction.
The damage did not remain in just one place. The flows of the arteries, veins, and nerves
running through his entire body like spider webs gave him a strange pulse and pain
while bringing their presence to the front of his mind. He was made strongly aware of
the expansion and contraction of his organs as well as their locations. More sweat
flowed from his body in an instant than if he were to enter a sauna. That clear and
unpleasant liquid mixed with something red. Accelerator thought small scale explosions
were occurring in various places across his body. That prediction was not wrong.
But he continued because he had no reason to stop there.
“Ohhhhhhhhhhaaaaaaaaaaaaaaaaaaaaaaahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh!!!!!!”
A wild yet solemn voice similar to a primitive aborigine dancing song spread throughout
the white land.
His entire body was soaked in blood and countless wounds were being expanded from
within, but there was not even the slightest shaking in his voice. That was the strength of
his will. He wanted to save a certain small girl. With that feeling alone, he overcame the
very real pain and carried out his high-level mental work without the slightest error.
