-it's pulling~, it's pulling out this one's ass~"
On the mountain side of the northern mountain range, where trees were mowed down and the dried up river was in ruins, a truly miserable voice rang out. It was a woman's voice. A voice that was not spoken, but rang out just like a wide area version of telepathy. Because a dragon's vocal chords and mouth were incapable of speaking human words, it definitely used a method to transmit words through air vibrations.
However, it was impossible for demonic beasts to speak in human words in the first place. Currently, the only confirmed case was the human-faced fish from somewhere. Even among the general population, there shouldn't be an existence such as a demonic beast capable of understanding human language. Furthermore, the existence of the Black Dragon right before their eyes was strange in and of itself. It was the first thing to ever endure so many shots of Hajime's railguns excluding the ones in Great Dungeons. Moreover, although there were powerful demonic beasts that could fire such Breath, they shouldn't exist around this place. If they lived here, then the danger should already be widely known.
Therefore, he deduced two possibilities as to why it's here. First: it was possible this Black Dragon came from further than the fifth mountain range, a completely unknown demonic beast. Following that, the other one was....
"You... ... don't tell me, are you from the Ryuujin race?"
"Mu? Indeed. This one came from the prideful Ryuujin race. Isn't that great? Isn't that amazing? That's why, although this one wants to pull it out of this one's ass... ... this one's magic power is about to be cut off. If this one returns to original form in this situation... ... it'll be awful... ... this one's ass will."
Hajime thought it couldn't be possible, but the Black Dragon replied, saying he was correct. Hajime was surprised in the "edge" of his mind. Just how many times since he coming to this world did he meet "rare existences." Yue was from the Vampire race that should have been annihilated in the wars 300 years ago. Shia was the current generation's atavism, and right before his eyes was the Black Dragon who came from the Ryuujin race, which was believed to have been annihilated more than 500 years ago.
"... ... Why are you in this place?"
While Hajime was still surprised, Yue continued to ask the Black Dragon. The Ryuujin race was a legend even for Yue. She was interested in whether or not it was the only living one of its race, just like her. The light of curiosity dwelled in her eyes.
"Well, more importantly, the ass... ... the amount of magic power remaining is about... ... eh, ah, please stop! Poking it is not good! The stimulation—! The stimulation—~!"
Because the Black Dragon ignored Yue's question, speaking with a delinquent-like attitude, Hajime said, "You dare to ignore Yue's question, Aa?," while using his fist to drive in the stake sprouting from the Black Dragon's butt. With the shock directly spreading inside its body, the Black Dragon let out a scream as it writhed. Its dignified appearance as if it was a death god when they first met was just like an illusion because not even a bit of that remained.
"Just why would the should be perished Ryuujin race be here, attacking mere adventurers... ... I also want to hear about that. Normally, I'd just pierce your ass as is, but I'll delay that to hear your story. Well then, tell me briefly."
Hajime thought the actions of this legendary Ryuujin race were too unnatural. Normally he'd be merciless, but he slightly delayed that as he urged it to speak. And he continued to grind the stake with his hand.
"Ah, kuh, stop grinding it~ nanojya~. I-I'll tell you!"
Hajime's action astonished the surrounding others, but Hajime didn't mind them. Because it couldn't talk if he kept it up, Hajime stopped the grinding. However, his hand was still affixed to the stake. The Black Dragon was relieved when the grinding stopped as it let out a sigh. Following that, it began to talk about its circumstances in a somewhat hurried tone. The captivated tone must be just their imagination.
"This one was being manipulated by someone. This one didn't have any intention to attack thou. The temporary master ordered this one to find the young man over there and his companion and kill them."
The Black Dragon turned its gaze towards Will. Will was twitching for a moment and his body trembled, then he firmly returned the Black Dragon's gaze. Having seen Hajime's fight, he must have settled something.
"What do you mean?"
"Umu, this one will talk in order. This one...."
When the Black Dragon's talk was summarized, it became something like this.
It seemed this Black Dragon went out of the Ryuujin race's hidden town for a certain purpose. Its purpose was to investigate the visitors from another world. Although the details were omitted, there was a person with high magic perception inside the Ryuujin race, and it seemed that person perceived a huge magic discharge and some things arrived to this world several months ago.
Although the Ryuujin race had a law which prevented from involving themselves on the surface stage, but just as expected, to leave the the matter of unknown visitors as an unknown was something that'd be dangerous, even for them. After some discussion, they decided to start the investigation.
The Black Dragon before them left the hidden town with the purpose of investigation. Normally, it'd turn into human form after passing the mountain range, then it'd work hard in secretly gathering information, but it thought to rest a little before that, and it seemed to have taken a rest in the vicinity of first and second mountain range. Naturally, it used the Ryuujin race's peculiar magic; "Dragon Form" and turned into the Black Dragon because there were demonic beasts in the surroundings.
And then a man completely covered in black robe from head to toe appeared in front of the sleeping Black Dragon. That man gradually gnawed on the thoughts and mind of the sleeping Black Dragon using the using a variety of brainwashing and suggestion magic from the dark magic system.
Naturally, if that happened it'd usually counterattack. But the Ryuujin race had a bad habit. That's right, it was the one that became the origin of that proverb. Ryuujin race that entered deep sleep in dragon form wouldn't be easily awaken. However, it was as long as no one kicked its ass. Even so, Ryuujin race boasted the toughness of their willpower, so it shouldn't be easy to manipulate it.
Then, for how it was able to be perfectly manipulated. That was....
"That man is frightening. His aptitude in dark magic can be called the level of a genius. That man continuously used magic for one full day. So no matter how strong this one is, this one couldn't endured it after all...."
It's the greatest mistake of this one's life!, was the feeling that came from the Black Dragon's sorrowful voice. However, Hajime just tsukkomi'ed that with cold eyes.
"In other words, having come here to investigate, how can you not notice magic being used for a full day, just because you're fast asleep?"
Everyone's eyes look somewhat foolish. The Black Dragon turned its gaze towards the day after tomorrow, and it continued its story as if nothing happened. By the way, the reason it knew it took a full day was because it was still conscious even after the completion of brainwashing, and heard the culprit grumbling, "For it to take one full day....".
Afterwards, obeying the robed man, it helped brainwash the demonic beasts in the second mountain range. Then, on a certain day, the Brutal army was moved to the first mountain range, and they encountered Will's party who were undertaking the investigation request. Having received the order to kill any witnesses, it chased after them. This one alone reported to the robed man. For some reason, it seemed it'd be bad if the fact he had brainwashed a lot of demonic beasts was revealed, so he ordered the Black Dragon to do a complete search.
Then, by the time it'd noticed it, it was already knocked down by Hajime, and panicked because she'd be dead if this kept up. That's why it exploded its magic power.
Following that, at the time it was going to do suicide attack according to instructions ingrained in its brainwashed brain. Its consciousness was blown away after Shia's attack. In the next moment, its mind immediately woke up from an indescribable stimulation and impact to its ass. It didn't know whether it was the blow to its head or its ass that made it regain its senses.
"... ... Stop playing around."
Towards the Black Dragon who finished its story came a shaking voice that was desperately trying to suppress its fury. Everyone turned their glances towards that person. With his fists clenched, Will's aimed his anger filled eyes towards the Black Dragon.
"... ... Just because you were manipulated... ... Gale-san was—, Navarre-san was—, Lento-san was—, Waslee-san was—, Kurt-san was—! Killed but that couldn't be helped you say!"
Apparently, he was angry because he understood why the adventurers were killed. He raised a voice filled with fury towards the Black Dragon.
"... ..."
The confronted Black Dragon didn't raise any rebuttal. It just received all of Will's words with calm eyes as it gazed at him. He was unable to stomach that attitude.
"In the first place, your story can't be proven to be true! You most likely made it up because you didn't want to die!"
"... ... What was spoken just now is the truth. For the Ryuujin race's pride doesn't allow this one to lie."
Now, Will tried to argued vehemently. But, Yue intervened.
"... ... Surely, it didn't lie."
"Kh, what's your basis for saying that...."
Having glanced at the snapped Will, Yue began to talk as she looked at the Black Dragon.
"... ... The Ryuujin race is noble and honest. I've lived much longer from everyone here. That's why I am more familiar with the legend
