As Yogiri thought things over, Higashida made the first move, stretching out his right hand. Yogiri judged that there was no real danger in the action. Higashida had no obvious intention of killing them, and his palm was facing away from them anyway.

“Fire Ball!”

Higashida’s hand began to glow, and in the next instant, something blew past Yogiri. That was it. Thinking it over, Fire Ball had to be some sort of flaming sphere, right? But Yogiri couldn’t see anything like that, and there was no sound of it hitting the bus behind them either.

A few moments later, the sound of something heavy falling came from behind them. Turning around, Yogiri saw a bizarre sight. The rear half of the bus had disappeared.

The sound he had heard was the remainder of the bus falling over onto the ground. A straight line had been gouged into the landscape, the now naked earth carving a path towards the forest in the distance, where a large hole had opened up.

In short, whatever Higashida had fired, it had erased everything in its path without a sound. Who knew how far it had actually traveled before fading away?

“As always, Sir Higashida’s Fire Ball truly beguiles the senses! No need to charge, yet displays such first rate power! In possession of such strength, he is confident enough to say, ‘No, it’s not Hellflame. It’s Fire Ball!’”

Despite Hanakawa’s flattery, Higashida didn’t seem especially satisfied. While he didn’t seem to have even considered the possibility of a counterattack, with an ability like that, it wasn’t surprising that he would look down on everyone else as if they were trash.

“I can only use basic magic. So I went ahead and refined it as much as I could. I could even kill a Demon Lord with it now. I was the one who blew off the top of Mount Caluone, you know.”

...

“Die.”

Yogiri unleashed his power.

“You fool! Simply telling someone to die like that speaks so ill of your vocabulary...”

Hanakawa must have thought that Yogiri’s statement was nothing but vocal resistance. But as he scoffed at them, he noticed something was wrong.

Higashida had collapsed to his knees beside him, then proceeded to unceremoniously fall onto his face, motionless.
