The Connection by Blood

When Mark returned to his stolen home, it was going to be the last time. His castle would from now on become his real home and it was in the perfect place to keep people he did not want. Especially from the mortal races. A Super Volcano like the one Mark took for himself would be safe from most beings meaning he would not be disturbed/

Of course, he planned to make the Super Volcano even better, but for now, he wanted to say goodbye to this home. It was the first home in this world he had called home and the way he got it was funny.

Mark sat down on the couch and placed Runeas' head on his lap. Grimnar jumped on the couch while Celestine got on his head like always.

"I may have gotten this house in a dishonest way, but it is a funny story. I am not going to miss this place, but it was nice."

He looked down at Runeas who had made it nice to be here. Her personality was a good counter to his harsh one which was a balance. He had noticed before that the more and more draconic he became the more his already amoral personality became even worse.

'If not for her, Rias, and Ddraig, I might have already become an Evil Dragon. Ddraig, am I an Evil Dragon?'

[A Evil Dragon is called a Broken Dragon, a being who are vicious battle maniacs who desire nothing more than to destroy, everything and themselves. You are a battle maniac, but you do not desire to die or destroy the world so no.]

"I see, might as well start brainstorming a cool dragon name for me. Imagine it, I fly in as a giant dragon and when I say my name, tremble before Mark, The Earthbreaker.

[HA, that would suck. Your name is good as long as you have your human form, but once you transform you do need something more dragon-like. Give me some time, but for now, help Runeas. Your blood is powerful and only because of how strong she is is she not exploding.]

"Got it."

He was taking a gamble by giving her his blood as his bloodline was that of a Heavenly Dragon. A regular being who consumed it would be destroyed from the inside, but Runeas was not just any regular being.

She was his and she was a pure-blood of her race and one of the strongest. He could feel it as his blood entered her Bone Marrow and began to fuse with her Devil bloodline. Her Crimson hair took a darker shade of red and two black burning horns grew from her head.

Her canines got a tiny bit longer and sharper. That was all the physical changes on the outside. The inside of her body began to undergo massive changes as her Devil Blood and Mark's fused into one. Though, she did wake up quite fast despite not being able to move. When she opened her eyes, her lavender eyes now were slitted like a dragon and seemed to blaze with power.

Mark leaned in with a smile.

"That went by faster than I expected."

As she could not move her body or Demonic Power she just spoke to him.

"Now, I have your blood. I take you are marking me, Mark-ing. Ha, OW it hurts to laugh?"

He reached down and stroked her hair.

"I am surprised you can still speak. Your heart and lungs must be in agony right now?"

Runeas would have nodded if she could.

"Oh, they are."

At that moment she felt a weird mix of Demonic Power and Dragon Aura rush into her heart and lungs. As she was not a monster like Grimnar, Celestine, and Astrid so it would take her longer to make her a Dragon Heart.

She went mute as the changes happened to her lungs. Seeing her like that made him smile as he picked her up and laid down using the big body of Grimnar like a pillow. It was not like the dog minded at all as he curled up on the big couch to get comfortable.

At the same time, Mark placed Runeas on his body with her back on his chest. He wrapped his arms around her as he decided to help her relax a bit as the changes happened. Considering how much bigger Mark was than her she could easily lay on top of him like this. She closed her eyes as Mark rubbed her head.

"Just relax and let the process happen naturally. Eventually, I will give you my Bone Marrow. That is my gift."

She closed her eyes and sent him a telepathic message.

'So, any woman who you consider yours will get this?'

Mark nodded with his eyes still closed.

"Yes, Dragon's Blood is truly powerful and this right will only be for my women. Eventually, when Rias comes back I will give her the same."

Runeas began to fall asleep, but she asked one more question.

'What about her peerage? Did any of them catch your fancy?'

"No. None of them are worthy of me, as they are now. And possibly they won't ever be. For now, just go to sleep."

She fully closed her eyes as she began to sleep in his embrace. Mark closed his eyes as well as he fell asleep hopefully, for not a long time. This would be the last time he slept in this house before he moved full-time to the castle in the Volcano.

---

When Rias teleported into Mark's house she found him and Runeas snoring on the couch. Grimnar slept as Mark's pillow while Celestine hung from the ceiling like a bat. She had seen a documentary Runeas left on and got the idea that cause she had wings and bats had wings she had to sleep like this.

Though she and Grimnar were woken up by Rias who looked at her before sleeping once more. She was someone their master liked so they had nothing against her or any worries. Though one of Grimnar's ears was pealed for her, listening.

Rias looked at her ancestor who now had horns which was odd. She then looked over at Mark who was the most likely suspect.

'What did he do?'

Her curiosity was rising so she walked closer. Rias walked over to Mark who had his eyes closed. She had heard that dragons were deep sleepers, so she was curious about something. She poked his cheek a little and saw he did not wake up. She ran her hand through his black hair a few times before she did the same to Runeas.

'Her hair is darker and softer? Those horns look like they are burning.'

She touched the horn and pulled her hand back as they were burning hot.

'That hurt.'

She then looked at Mark and smiled. She kneeled down to get a closer look at his face. The man who she thought of as her first boyfriend. She wondered what the Phenex family would think when their son's fiance was married off to a dragon.

'Fools, I won't let them know about him until I show their blonde chicken his place. Though, seeing Mark humiliate him would be cool. Speaking of, isn't he kinda cool and handsome like this.'

She looked at Runeas who was snoring and then at Mark who was breathing soundly. She leaned forward and kissed him once on the lips feeling proud of not waking him up.

But just then, Mark's arm wrapped behind her head as he pulled her down again. He caught her lips again, but he shoved his tongue in her mouth this time. He caught hers with his and began a very deep kiss with Rias.

Her eyes went wide open as she tried to pull away, but he did not let her. Though when she became short of breath he let her go which caused a line of their saliva to form. Mark licked his lips clean and laughed at her.

"Thank you for the meal."

Rias covered her mouth as her face was crimson red. Much like her hair.

"You fiend. That was my second kiss."

Mark nodded as he sat up Runeas waking up with him. Taking the chance, Grimnar moved out of the way to not be a pillow. This time she sat up and exhaled hot smoke. She started to cough like she was a smoker as her heart and lungs fired up. When her Dragon Heart began to work, she felt a rush of energy.

"Holy shit. Is that what you feel like all the time?"

Mark shook his head.

"No, that feeling will go away with time."

Runeas sighed in relief as she got off Mark and stood up.

"Finally I can move."

Rias looked at Mark who walked toward her. She had to crane up her head to look at Mark's face. She had to do that already, but as this was the first time she saw him after his evolution she noticed he was both bigger and taller.

"Mark, are you bigger?"

Mark made sure he did not get even taller, but at the moment he was 6'11 which would be his last growth in height ever. As for his muscles, they were big, but they had more density than the real size. Meaning he did not look like a bodybuilder, but he was not lean.

"Yes, I am. I am now, a Heavenly Dragon, Ophis herself said so."

Hearing what he said made Rias take a double take at him.

"Ophis, Ophis the Dragon God?"

Runeas nodded.

"She was here a few hours ago. She wanted to talk to Mark as Dragons of the Heavenly Dragon rank are rare."

[Of course, we are rare. I and Albion were the only one before I started to train Mark as my heir and Crom Cruach and Tiamat trained like crazy. Then you have the Evil Dragons who made even me and Albion warry.]

Hearing that made Mark look at his left hand.

"So, you and Albion were the only Heavenly Dragons, BUT, you had other dragons who could fight you?"

Runeas squinted her eyes at Mark's hand.

"Lazy."

[Wait, that is not fair. Remember that I crated two unique abilities that none of the others have.]

Rias brought up a good point.

"If you and Albion created your abilities, what is to say that the Crom Cruach and Tiamat did not? What about the Evil Dragons?"

Mark followed this up.

"And you have been sealed for so long that you have not grown. Once I free you, you bet your ass I will put you through some harsh training. You can do so much better."

[Sniff, thank you, Mark.]

"No problem Ddraig. Now, Rias. Your turn."

Rias looked up at Mark who bit his tongue causing it to bleed. With some telekinesis, he drew a drop of blood from his mouth holding it in front of Rias. She looked at his blood and felt the power in it.

"Can I take this?"

He nodded.

"You have me to keep you safe. When you wake up you will feel completely different."

She nodded and opened her mouth and swallowed the drop of blood. The instant Mark's Heavenly Dragon bloodline entered her body the power in it was released. Mark hugged Rias and using his whole body he helped her assimilate his blood.

Runeas now that she could walk smiled as she walked off.

"Take care of her. I will gather all our stuff as this will be the last time we come here."

He sat down on the couch as she sat Rias on his lap like she was a child. He sent his mana into her body to take control of the rampant Dragon energy rushing through her body. He began to fuse his blood with her Bone Marrow much like he did for Runeas.

Though comparing Runeas and Rias was like comparing a cat and a lion. Runeas was a First Generation Devil and very powerful, while Rias was a distant descendent though she was still pure-blooded. Though her young age did not give her a lot of time to grow stronger so he had to help her more.

Not like he minded as she was his anyways. Part of his harem which was part of his hoard. And he would guard his hoard and harem jealously.
