aim diffusion field

“That’s a device used to disrupt AIM diffusion fields. The main body is probably part of
the dome. At the Youth Correction Center of this city, isn’t there AIM disruption devices
to prevent people using their ability to escape? The one above us is the board of
directors’ special edition, and the setting right now is probably most targeted at you. For
a shelter that can withstand nuclear attacks, the ones they are most afraid of are those
with the teleportation-type ability that can ignore three-dimensional defenses.”
Having heard that, Musujime took out her military-use flashlight from her belt and
waved it around a few times in her hand. She then furrowed her brows.
“...Though my ability can still work, it feels like it’s been forcefully redirected. Even if we
teleport we’ll probably be buried underground.”
“As a member of the board of directors, and also as a weapons specialist, he should
understand my military value. Then he should know the underlings of that standard
cannot possibly take me down,” said Accelerator with a bored voice disdainfully. “But, if
they got a sample of my AIM diffusion field from previous battles, they could reverse
calculate from the data and then send out disruptive electrical waves. With the progress
from the data analysis they could at least force our abilities to go berserk and take me
and Musujime down. That’s the plan of those bastards.”
