Stun Grenade

It came from down at his feet. He looked down and saw a metal cylinder about the size of a coffee can. However, it did not have pull tab like a can of coffee would. Nor did it have an opening to drink from. Instead, the top of the cylinder had a device to hold a pin, but the pin itself was gone.

Kamijou’s mind blanked.

He had just realized what had been thrown toward them.

And the English words written on the side of the cylinder entered his vision.

Stun Grenade.

“...!?”

He did not even have time to shout out.

An explosive noise like a high-pitched scream and a sun-like flash of pure white light exploded through his various senses. A stun grenade did nothing but make its target falter due to the powerful light and noise, but at such a close range, Kamijou felt like he
had been hit hard on the head and was knocked to the dirty ground.

Some random delinquents in the area would not have that kind of device.

That meant...

(Shit!! Has Anti-Skill caught up to us!?)

The light and noise had already disappeared, but an intense afterimage was burned into Kamijou’s eyes and a ringing in his ears seemed to follow him around. Even after blinking a few times and shaking his head, his vision was still mostly gone.

(Index!! Fleiss-san!!)

Kamijou cried out, but he could not hear his own voice. They may have responded, but  Kamijou could not hear anything.

His vision was warped as if some powerful glasses had been forced over his eyes, but he could see a number of legs. He could tell some people were approaching, but his ears had not recovered enough to hear their footsteps. He just barely managed to notice that the approaching figures were holding something. They were most likely guns. If he stayed there, he would either be captured or shot, but his semicircular canals must have been taken out along with his sense of hearing, so his legs would not move as he wanted them to.

Suddenly...

“...The established five colors symbolize the five peaks. Therefore, the opposing five complementary colors become that which amplifies the elements of the five peaks.”

Kamijou’s hearing had been destroyed by the stun grenade, but he heard a smooth female voice.

It belonged to Fleiss-san.

“A red background bordered with a green outline. Triangle of Tejas, bring forth your great natural power by way of that emphasized symbol!!”

If Kamijou’s vision had been working properly, he would have been able to see the following.

Fleiss-san lit an oil lighter in one hand and pulled out a green card with her other hand.

The card looked like something a soccer referee might have and she held it between her index finger and middle finger. She waved it horizontally as if to slice the small flame of the lighter in two.

A great noise exploded out.

An orange explosion burst out. The highly directional explosion did not even come close to charring Fleiss-san, Kamijou, Index, or even the walls of the buildings to the right and left, but it accurately blasted the approaching enemies out of the alleyway.

“Young Kamijou and the nun, are you okay?” asked Fleiss-san.

Kamijou and Index nodded while staggering around.

And then...

“Tch. Now you’ve done it, you and your damn analog magic,” said a voice.

Kamijou’s senses were finally recovering after the blast from the stun grenade.
