Chapter 16: Big, Adorably Cute Eyes

By then, I had already put away the gun in my hand,

but... that didn't mean I wasn't on guard.

Because... a coin had already appeared in my right hand.

If these people tried anything funny, I wouldn't mind firing a shot right here.

Why did that sound a little weird?

The more I thought about it, the more I felt... it sounded like something you'd say about getting exercise for fun.

Hmm... well, as Railgun Sister, firing a shot or two was no big deal. So be it.

I used to be a guy, after all. There was nothing wrong with firing a shot, right?

Though I didn't have that function anymore, I still remembered how it felt. Yeah... probably.

I followed the four of them all the way to the villa. Nothing happened, and by then I had

already brought both hands in front of me, ready to fire

an electromagnetic cannon at any moment. Though I called it an electromagnetic cannon, it felt more like a coilgun.

But whatever~ Railgun Sister in A Certain Magical Index basically used a coilgun, too.

Strictly speaking, both railguns and coilguns fell under the category of electromagnetic cannons, but the latter

was more difficult, because it was hard to set

precise parameters for the firing time and the distance the bullet traveled.

In practice, coilguns were more difficult to build than railguns.

An electromagnetic cannon formed a powerful linear electromagnetic force behind the projectile and launched it, so it didn't need

to calculate the activation time of the magnetic force with much precision.

Put it this way...

An electromagnetic cannon launched bullets out of the barrel, while a coilgun used magnetic force to fling them out.

In practice, there wasn't much difference.

In short, both were powerful technologies that used electromagnetic
