hundred of wings

While the two exchanged blows between fist and wings, the Level 0 probably didn’t
know why it had turned out this way either. Accelerator himself probably didn’t know
what he wanted to say; it was just air passing through his lips, no one else should be able
to understand him.
Instantly, both of them went silent.
They moved their gaze towards the small girl collapsed on the ground.
The black wings swelled up even more than before.

The pair of wings split into over one hundred and attacked the Level 0 from all angles.
At the same time where the sound of explosions and shockwaves ran rampant, the
ground started to tremble dully.
(He should be dead now... it’s impossible for him not to be.)
Accelerator thought.
It was impossible for that not to be the case.
Even so.
“Why...”
Accelerator let out a sound that was almost like a groan.
In the end it turned into a mighty roar.
“Why couldn’t a hero like you just die!? If you die, then everything can finally break
apaaaaaaaaaaart!!!!!!!!!!!!”
He heard the reply.
Right in front of him, the teenager that clenched the blood-covered fist spoke.
“...Things like heroes are unnecessary.”
Footsteps rang out on the snow.
Fist and wings collided.
The air shook, many attacks impacted, and blood flew out.
“Does a Level 0 like me really seem that incredible!? Hero? Villain? Stop kidding
around! Can’t you save someone if you’re not standing at that spot!? In front of your
eyes are people crying that don’t wish to cry! In front of your eyes are people that can
only clench their teeth while struggling and can’t even say the words ‘please save me’! Is
that not enough!! Just step up already!! You don’t need special positions or reasons!!
With these, you can step up and be a shield for them!!”
After letting out those words, the Level 0 became stronger.
