someone copies IB and blows off their arm

Rensa could theoretically use any esper power, but she was really only using her ability
as a cyborg to create an output point for the power. As she was only borrowing the
power, a power would forever disappear from her stock if the original owner died.
As such, she sometimes felt it was a waste when she had to kill the owner of a rare power.
However…
(I must keep my priorities straight. I must kill Kamijou Touma to eliminate this mid
level problem.)
Her desire never left the realm of a personal opinion. She prepared to use the #1 power
in Academy City which was one of her presets. She would use the point of contact at his
throat to reverse the flow of blood and electrical signals in his body.
And then…
“Ohhh!! Ooooooooooooooohhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh!!”
She heard a yell from the side.
It seemed Kuroyoru Umidori was trying to do something. She was about to use the #1’s
reflection, so any attack Kuroyoru might use would have no effect.
However…
Rensa had a slight thought. An ever so slight thought. Kamijou Touma would die here.
He would die before she could try out his rare power even once. Kuroyoru Umidori was
interfering before she would even have the chance. The desire to try out that exceedingly
rare power rose back up within her.
While Kamijou dangled down from her hand, Rensa held her other hand out toward
Kuroyoru.
The giant “flower” opened from Rensa’s back and the countless “knitting needles” shot
out, pulling the many “threads” within her as they did. This action could easily have
killed any human with a proper sense of pain, but Rensa’s body only swiftly altered its
characteristics.
She was creating the characteristics needed to call in Kamijou Touma’s power.
She met all of the necessary conditions.
And…
Imagine Breaker flowed in.
She could feel something passing through the arm she held out toward Kuroyoru. She
could feel it gathering beyond her wrist.
This was the power to negate other powers.
It was the perfect defensive power.
But…
The arm Rensa held out toward Kuroyoru suddenly swelled up like a balloon.
“Ah?”
She grew confused.
It resembled a lithium battery used in cell phones or laptops when it was destroyed due
to over-charging. Tremendous static ran up her arm and spread across her body. Her
very thoughts were thrown into disarray.
(Dh…gh…What!? High level problem detec-… I-I-Imagine Breaker should be nothing
more than the power to negate other powers. Why is it causing such great
destruction…just from being drawn into me!?)
Her mind raced around in search of an answer.
Then she finally realized this was no time to be leisurely seeking an answer.
(E-e-emergency release…of body wiring…!! Dz…Command not…received…
Fatal…problem…detected… Th-this is…!!)
She tried to open the giant “flower” from her back, but it only opened halfway and
convulsed violently. Swapping out the wiring based on precise values would be
impossible.
An unpleasant noise burst from deep inside her head.
Rensa lost all sense of up and down and she collapsed to the side like a piece of wood.
♦
“Cough!! Cough cough…! D-dammit!!”
After finally being released from Rensa’s grip, Kamijou kneeled down on all fours and
coughed with a hand on his throat. He almost felt like the oxygen suddenly rushing into
him was destroying his body from the inside.
Rensa had not moved ever since she collapsed.
The unnaturally swollen arm had completely blown off. Various cables and metallic
parts were strewn across the road.
(What…was that? Did she have some kind of machine trouble?)
