vectors a bomb away

It was an immense amount of energy. A bomb.
Accelerator, who was the closest to Misha at the time, ignored the rapidly diminishing
power of his electrode, and flew towards the archangel at full power.
(...Who gives a shit what just happened, this isn’t the problem at the moment!)
The power to rush ahead towards the glowing mass of energy.
The strength that Accelerator had lacked from the moment he escaped from Academy
City and arrived in Russia.
The strength that boy had planted in him after their confrontation, finally blazed up
within Accelerator’s chest, and exploded.

(Ahh!! Fuck, I admit it! I want to protect her! I don’t want to lose her!! I don’t even want
to think about the possibility of losing her!! I will face anything in order to protect this
dream of mine!!)
Accelerator would not be able to suppress that enormous energy just with reflection.
Facing the angel of science, whom he has not yet determined to be friend or foe,
Accelerator yelled with all his might.
“Stop that thiiiiiiinnnnnnnnnnnnngggggggggggggggggggggggggg!!!!!”
Did he make it in time?
Was there still time to act?
The next moment...
The mass of energy exploded.
A pure white sphere of light exploded outwards, consuming everything in its path. Even
if one closed their eyes, they would still have been blinded by that tremendous light. The
pitch black night became a ceiling of pure brilliant white.
Everything within a radius of several tens of kilometers should have become ash. This
was not a simple explosion, but one of a “special power”. It would not have been weird
for some crazy side effects to be produced. There was a very high chance that the
explosion could have turned the surroundings into an uninhabitable wasteland.
However, as the explosion expanded outwards, it started to warp unnaturally.
The angel of science threw the gargantuan energy inside it at Accelerator, who
manipulated the vectors inside that energy into a transparent shield and threw it around
the ball of energy. Like a shell, it encased the explosion which had already expanded to
three hundred meters. Inside the shell, the energy from the explosion built up as the
expanding light was trapped, unable to unleash its wrath on the land.
It seemed impossible, but the light and sound intensified even more.
But Accelerator did not give up, and mustered all his strength, strengthening the barrier
around the giant orb of light.
For several seconds, the mass of energy was contained inside the shell.
