“Then I’ll start by attacking that Mathers guy and judge the rest by how they react.”

“Oh, Kamijou-san, you should really cover your ears.”

They started with a single shot.

This was the Liquid Proof Railgun.

This was the fearsome attack that had torn holes in the Windowless Building which was built to withstand a direct hit from a nuclear weapon, but they unleased it upon Mathers as their very first attack.

The shockwave burst out a moment later and the surrounding air raged about as a violent wind. The intense heat turned some of the atmospheric components to plasma, so light flashed intermittently through the air and made it briefly impossible to see. The process was entirely different, but it felt a lot like seeing stars after taking a blow to the head.

In a way, this blast was stronger than the #1.

It was unclear if it had annihilated Mathers, but Kamijou needed to get back up on the carriage roof during this “fluctuation”.

Even if he felt stable here, this was not over. Even if he did have a lifeline, the risk of death did not just disappear. He moved from the colossal motorcycle to the carriage wall and climbed up to the roof. The carriage had used its speed to shake free of the dangerous wind and plasma storm, so the view was washed clean.

He was there.

That great presence stood there.

The boy could tell the stability and lifeline he had sensed was slipping from his fingers. A single mistake would mean death. No, this tension was so great that it felt like a miracle he was not dead already.

The smell of the sea breeze was fading.

He was not too knowledgeable of British geography, so he could not picture where they were on the map. Still, he could tell they had passed one stage on their journey and were drawing ever closer to Scotland.

And that meant his opponent could not waste any time either.

Not even the attack that had brought down Board Chairman Aleister’s strongest fortress had been enough to destroy that man.

Mathers’s thick cloak and scarf flapped behind him as he stood in the same spot as before. He would not be taken out like Edward Berridge had been. Seeing that, Kamijou fiercely bared his teeth and spoke his mind.

“You damn monster.”
