A Powerfull Assassin On Parallel World Become Demon Lord?!

Currently, Ryuga was on his private jet and headed to the previous battlefield with Arcadia yesterday. The flight was quite smooth, but Ryuga didn't have any ideas, where this jet come from. He just used his Gift,[Summoning].

Perhaps this jet was forcefully transferred into this Parallel World like him. Not only he can summon living creatures, but Ryuga also can summon big objects like this. On the Gift's description, he almost can summon everything, except for Goddess, because she was already dead.

"I could use this Gift to summon something useful in the future.", Ryuga already thinking various plans with using his Gift.

[Master, you should think your future plan]

[Would you follow the Goddess instructions and live as Demon Lord?]

[You have a human appearance, so you can dwelling in Human Country]

His AI giving him a piece of advice, but Ryuga had been thought that even before the AI told him. He is Human and the Heroes were thinking the same too when they met.

"Indeed, living as human will make everything comfortable for me, but I want to know about this Demon Lord stuff. There was another Goddess that mentioned on the Demon Lord's description in my status. I want to find the truth and minimize the obstacle for return to Earth."

[But that was pretty dangerous and quite troublesome.]

"Which one do you prefer, Fighting against 108 Demon Lord or Fighting with thousands of Heroes?"

The Demon Lord was fewer than the Hero, so he won't take much time just for investigating them. The other Goddess also on the Demon Lord's side, so he can kill two birds with one stone.

"Ah...I can see that dragon." , From the distance, Ryuga can see Arcadia because the dragon was standing in the middle of the wasteland.

The ground was demolished and there are countless craters with big sizes scattered around. Not a single grass was able to survive the barrage of attack from two powerful beings. Even the temperature was raised for few degrees because the ground was still scorched by the meteor magic from Arcadia.

The dragon was smaller than before. His body was around 20 meters but the wing was still very large. Arcadia noticed that something flying above her and staring at unknown objects. Ryuga can't be landed on the ground because they were unsuitable for landing.

Ryuga slowing down the jet and lower the altitude. Once the jet slowed enough, he dropped the altitude until the jet almost reaching the ground. He doesn't use the wheels and he plans using just the body part for landing.

The jet made contact with the ground and Ryuga gets out of the c.o.c.kpit. With his skin covered with Nanoparticles, he could withstand the impact and didn't get any injuries, but his bones were screaming though.

The jet was continued to move until it exploded because the engines were destroyed. Arcadia becomes cautious with Ryuga because she thinks Ryuga trying to attack her.

She was staring at Ryuga while prepared dragon breath just for insurance. Ryuga also staring at Arcadia while sweat poured on his back. Thanks to the acrobatics act when he leaps from the jet, his body's condition was worsening.

"Yo, I am back as I promised." , He needs to take another method to avoid the fight. He chooses his words wisely since Arcadia can talk to him before.

But Arcadia still staring at him. She looking at Ryuga and the wreckage of the jet back and forth. She couldn't understand what Ryuga said because he was talking with Japanese.

'Is she wary about me and assume the explosion was an attempt to attack her?'

"Don't worry, I come here not to fight with you anymore. That explosion was an accident. That thing was something to carry me here.", Ryuga raising both of his arms to shows that he was harmless.

Arcadia then using Language comprehensive magic to Ryuga. He was able to understand Arcadia because Arcadia using that skill for her words to communicate with other races. Ryuga body was glowing slightly and make him surprised for a moment but he didn't feel panic.

"How foolish for me to afraid with human like you...I only surprised a bit.", Arcadia trying to playing cool, but the slight pause between her words showing that she was scared to Ryuga. She just bluffing to control the situation, but unfortunately, her opponent was Ryuga. He already knows that Arcadia was scared of him.

Arcadia was still recovering from the injuries from the battle yesterday. She lost almost all her mana just to healing her body, but that was insufficient. Honestly, she couldn't maintain the "Dragon" mode any longer, but she needs to become a "Dragon" in order to stand in the same position as the human in front of her.

If she showing her human appearance, she will lose her footing and Ryuga undoubtedly will control the flow. He was human and on top of that, he was crazy strong. Arcadia didn't have guts to expose her weak side and decide to gamble.

Not knowing about the light before, he was ignoring that because he didn't feel any negative effects. Ryuga has secretly admired the creature in front of him. He didn't have time to look at the Dragon yesterday, because he was too focused on the battle. The Dragon's body was very big and somehow he feels the Dragon had a quite majestic aura. Not to mention, this fellow was very strong too.

This was the first time for his Nano-suit to be destroyed to this extent. Not even several atomic bombs able to make a scratch on his suit. As a human, he also curious about Dragon power. If he had that power, he can trample his enemies with ease.

He also notices that the Dragon's jaw wasn't moving, so the Dragon using telepathy to communicate with him. He already knows that before, but this makes him realized this Dragon had so many cheats.

"Just who are you? Your appearance was human yet you holding such tremendous power. Are you a Hero? , Finally, Arcadia couldn't hold back her curiosity and asked Ryuga.

"Nope, I am not Hero guy, but I am the youngest Demon Lord.", Ryuga throws out his information without hesitation.

First, because this was Dragon and not Human. Ryuga doesn't have to worry about the information being leaked to Hero.

The second was because he wants to dig some information from the Dragon. In every Isekai novels, Dragon race was one of the oldest races, so they probably would know something about a way to return to Earth. There was no guarantee that was true, but at least he needs to try.

"Demon Lord? But you are human right?", Arcadia managed to hold back to showing her shock. A human claims to be Demon Lord. If she had met him before the battle, she probably will be laughing like crazy but his strength was no joke so what he said was the truth.

"I come from a different world because I summoned by a wicked Goddess. She stupidly makes me into a Demon Lord despite I was human just to entertain her. I got the [Summoning] gift from her and somehow I ended up with summoned you. That was something that I regret because I doing something similar to that stupid Goddess. That's why I will listen to anything you want except for losing my life. I need to return back to my world and meet with my family."

"So you spare my life wasn't because you pity for me?

"Yeah, thanks to you. When you saying that I was forcefully summoning you, I immediately realized that I was wrong."

Arcadia thought Ryuga just acting and pity for her, but when she listens to his story, she knows that he was an honest person.

"But If you are Demon Lord, you should have subordinates from Demon Race right? Your army before doesn't look like from any Demon Races. I mean they didn't have tail and horns. Their appearances like a human with full armor though."

"I never meet with Demon races aside from Goblin, so I don't know anything yet. Even I tried to make a contract with Demo Race, I doubt they will listen to me with my human traits."

"I see...", Arcadia voices carrying a deep emotion. She knows how he feels because she also experienced the same because she was different.

Just because she was born as Black Dragon, she was received harsh treatment. They only look at her appearance, not on her potential. She never runs amok even for once, but her family never believed her. Only her mother was always on her side, but she was very disappointed because Arcadia running away from reality and choose to deceive anyone by using the Golden armor to make her scale become Golden.

"Before I get my punishment, may I do something like preparation?", Ryuga trying to ask Arcadia while showing his intention. He wants to absorb the remnants of the Nano-suits first to strengthen his body.

"What do you mean?" , Arcadia asks him suspiciously.

"Like this." , Ryuga activated the power of Nano-suits and absorb the remnants. A large portion of Nanoparticles was swirling around him.

Arcadia instantly froze because the sight of Ryuga was the same when he using deadly attacks to her yesterday.

"Are you just putting an act and tried to kill me when I lower my guard?!!!", The dragon was roared as a signal of her anger.

"No, please listen to me!!"

"As If." Arcadia opening her jaw and prepared to release a massive torrent of Dragon breath.

Ryuga stopped the process for a moment and take something from his pocket.

"This is my treasure. I saved my family photos on this phone. If you destroy this, I won't able to see their face forever before I return to Earth."

Ryuga was showing his phone to her. He scrolls the pictures of his family as proof. Ryuga already moves the file on micro SD and what he showed was the photo on the phone memory. As long the micro SD was intact, he can summon another phone as a replacement. He didn't want to lose the precious photo of his family, especially his sister. He will have nothing to lose, but Arcadia was the one who will decide in the end.

"That was your family?", In a voice full of remorse, Arcadia asking him.

"Yes, they are the most treasured family for me." , Ryuga gaze at Arcadia firmly.No hint of hesitation showing on his face.

"I see, I will take this item as insurance.", Arcadia didn't know anything about Earth technology and she gradually accepts his suggestion. She already knows his language was different from the human in this world, so she didn't doubt his story.

"Thank you very much.", Ryuga then resumes the progress to absorb the remnants of his Nano-suit.

The entire process was not so painful like before because the Nanoparticles on his skin were slowly open the path to enter his body. But looking at your skin makes some little holes were quite horrible. If someone with trypophobia witnesses this scene, they will faint on the spot. While waiting for the process, Ryuga tried to have conversations with the Dragon. This is a rare chance after all.

"How I can I hear your voice?", Ryuga asking Arcadia to satisfy his curiosity.

"I used telepathy." , Arcadia answered shortly with the telepathy.

"Are humans like me able to understand your language?"

"No, I using magic to make you understand your language and vice-versa."

"I see.", with a nod, Ryuga continue his question.

"Then, can I talked to another race without the magic?"

"Absolutely not."

"Is that so?"

"Yeah."

It seems Arcadia didn't want to talk with him anymore, so he just sitting on the ground and waiting until the process complete but then Arcadia takes initiative to start the conversation.

"So what will you do in the future? You are a Demon Lord, so you are the enemy of Human Race. On another side, you have the appearance of human and that makes you won't be received on Demon Race. Other races won't accept you either because of your condition. Your situation was pretty bad isn't it?"

"Yeah, I just arrived in this world a few days ago, so I don't really have any ideas. But I will do my best to reach my goal to return to Earth."

"Even that means you need to kill someone like Hero that comes from your world?"

"If they become obstacle for me to return on Earth, I would kill them.", This was his resolve when he knows he has become the enemy of the Hero.

"You are quite unique huh...", Arcadia muttered under her breath, but Ryuga heard the telepathy clearly.

"What do you mean?" , Ryuga asking her as he was slightly interested to hear the Dragon's opinion about him.

"You don't know how harsh to live when you were different. You only can say that because you never experienced it yet. I already tasted the bitterness of being different within the Dragon race."

"You are different? What do you mean?", Ryuga looks puzzled and tilts his head?

"The Black Dragon was treated like a calamity because, in the past, the black dragons were lost control and attack fellow Dragon. They destroy the buildings and hurts a lot of Dragons too."

"But are you ever do something like that?"

"Never." , Arcadia's voice filled with sorrow and anger. Her tone was higher than usual.

"Then you are different from the rest of the black Dragon. If they just judged on the history of the past, all you need just to prove that you were different. You are special and not like mad Dragon."

"That's useless. They never believed to me."

"I see. You know, when I see you from close range, I admiring your figure. In my world, there are many pictures of Dragon, but when I look at the real one, this is one hundred times better."

"Huh...", Arcadia couldn't understand what he said.

"Black color was very cool you know. During the day, you will stand out very much and at night, you will blend with the Darkness."

"What are you talking about?.

"In short, you don't need to thinking about that matter anymore.You know yourself better than anyone. As long as you don't do what they said and all you need to do is to live the way you are."

Ryuga giving advice as his apology. If his words can comfort this Dragon then at least it can lessen his guilt.

"I believe there is a time for you to prove your existence was not a calamity. You also have a lot of positive values.Stop thinking about the difference and try to think about how to overcome it."

His words were slowly washing over the anxiety of Arcadia. She could tell that she find a comrade. Though his word not completely erasing her darkness, she still feels relieved to hear that. Somehow, she felt like scolded by her mother when she listens to his advice.
