breaks magic clothes

Kamijou’s appreciation gauge toward Index rapidly dropped and he stared at her clothes
with scorn.
“…Hmm. So if that really is a supernatural power, then would it be torn to pieces if I
touched it with my right hand?”
“Yes, but only if your power is real. Heh heh heh.”
“Perfect!!” shouted Kamijou as he grabbed Index’s shoulder.
As if he had grabbed a cloud, he felt a strange feeling like the impact was being absorbed
by a soft sponge.
“Wait…huh?”
Kamijou cooled his head and thought.
What if everything Index was saying was true (as unlikely as that was) and this Walking
Church really was sewn together with supernatural power?
Would negating that supernatural power send her clothes to pieces?
“Huuuuuuuuuuuhhhhhhhhhhhhhhhhhhhhhhh!?”
Kamijou reflexively yelled out at the sudden premonition he had that he was about to
suddenly go up a few steps on the stairway to adulthood. But…
…
…
…?
“Ehhhhhhh? ...Huh?”
Nothing happened. Nothing happened at all.
(Oh, c’mon. Don’t make me worry like that.)
Kamijou just could not stand it.
“See? What was all this about your Imagine Breaker? Nothing at all happened. Heh
hehhn.”
Index put her hands on her hips and puffed her small chest in pride.


But in the next instant, her clothes fell straight down like the ribbon on a present.
All the threads sewing her nun’s habit together had cleanly come apart, turning it all
into mere pieces of cloth.
The hat-like one-piece hood must have been an isolated item because it alone remained.
Having only her head covered made it seem all the more painful.
