Prologue – Those Lined Up Before the Horizon
As she spoke, Oriotorai stepped her right foot forward.
Her longsword was lowered to her bottom-left.
“Even if they have a gigantic body, strength, and armour, devils have a fatal weak-point.”
That weakpoint was this:
“Living creatures have skulls, and they have brains. If you shake the head, the brain will impact the interior of the skull and the nervous system will be numbed. That’s a concussion. An effective method of shaking the skull is to bludgeon something that’s closely related to the head. If you hit a location rather far from the head, the vibrations will resonate greatly.”
That location was this:
“For a human, the tip of the jaw. For a devil…”
Oriotorai moved. The right foot she had stepped forward acting as a fulcrum, she twisted her body right and forward, moving from the left.
Continuing on, she spun her body in one revolution, swinging her longsword as she evaded the path of the devil’s charge.
Filled with the momentum of her spinning, the longsword was swung. She let the tip of the sheathe run upwards.
“The tip of the horns on the head. Hit the slanted horn like you’re trying to hook it.”
As she spoke, the sheathe of the longsword, rising with a light movement, smashed into the left horn of the demon, who was passing by in its charging state.
A sound echoed.
It was nothing more than a single strike that had slightly bent the devil’s neck.
Advancing forward for a couple more steps, the devil suddenly lost power to its knees and it fell to the floor.
He did not fall because he could not control his charge. His knees had trembled, and he lost all balance.
The gigantic body broke the wooden deck, gouging out the structural material. Because of the impact, he braked in a short distance.
The crimson devil tried to stand, but though he was able to raise his waist, he could not force power into his knees. If he picked his body up, he would repeatedly fall.
Oriotorai stood before the devil.
“When devils and other gigantic living creatures go into this state, the nerve clusters in each part of their bodies will start working in place of the brain, so their recovery is fast. So before that happens…strike the position diagonal from the weakpoint.”
As per her words, she smashed his right jaw, which was diagonal from the tip of his left horn.
It was a strong blow. The devil’s body, which he could not put any power into, was unable to defend itself.
His neck twisting, he fainted.
“Actually, hitting anything that looks hard is fine. If you do so, the vibrations will resonate directly. These guys’ heads aren’t really exoskeletons; it’s just their endoskeleton jutting out. If you smash them from a perfect direction, it’ll directly resound to their brain. What you can’t do is hit from a direction like you’re trying to smash their neck in, from directly above or directly into the charge. Devils’ neck bones and backbones are one straight line, and they’re hunchbacks, so impacts from directly above travel from their back to their butt. That’s why you can smash their horns together during adolescence or puberty.”
While she was speaking, the crimson devil dropped prone and the door of the office behind her was hurriedly slammed shut.
Oriotorai glanced at the office.
“Aah, they’ve gotten scared of me.”
“Of course they have,” everyone said as they began to pick up their worn out bodies. In response, Oriotorai said this.
“Mmm, then, how should we go in? The entrance is probably being defended. Even though I’m leading everyone, smashing in from the roof is a little difficult…”
“…Um, what do you mean by lead, Sensei?”
“Mm? This’s a practical examination on a societal field trip. I gave a demonstration, right?”
“Like we could do acrobatics like that!”
“It’s all right, it’s all right. You’ll become able to do it now.”
Hearing her calm tone, everyone’s face turned pale.
At that moment. Suddenly, a young voice came from the side.
“–Huh? Hey, hey, hey, everyone, what’re you doing?”
Everyone turned to the boy’s voice.
A single boy was standing to the side of the class. He had brown hair and eyes that smiled. He was clutching two paper bags to the left of his long, rough and crumpled uniform that had chains attached to it.
He took a piece of bread from the paper bag he had gotten from a snack shop and put it in his mouth.
Someone spoke the name of the boy whose decorative chains clanked as he walked.
“Toori ‘Impossible’ Aoi…!”
