Fully acts through someone NTV7 C1 P4

A voice or a sound could possibly act as a trigger for some sort of esper power.

But…

“Oh? I sent someone to increase my information gathering ability because I thought something exciting was happening, but it looks like I found something even more interesting than I was expecting.”

“…?”

That voice sounded incredibly odd to Kamijou.

There was no problem with the tone or volume of the voice. As one would expect of a slender girl, it was a high-pitched soprano that sounded like it could cause a glass to vibrate. However, the intonation was oddly alluring. It was as if an adult’s voice was being forced to sound younger with a voice changer.

Also, the actual words spoken were odd. The bobbed hair girl had said she “sent someone” despite standing right in front of Kamijou.

And then…

The bobbed hair girl spread her arms wide and ultimately brought one hand up to her eye in a horizontal peace sign.

As she gave a casual wink, Kamijou noticed something like a star in her eye.

This action did not fit at all with her original obedient image and she then spoke with a superior elegance.

“I am Shokuhou Misaki, Academy City’s #5 esper. Nice to meet you☆”
