Vespera's Confusion and Rias' Worry.

(Finally fixed the image of Vespera. It gets past the filters now. Image here. Also, I have decided on the name of the Domain Expansion: Carastrophic Singularity.)

It was a good thing he had Vespera on his side as she was a truly powerful being. As the great-granddaughter of Zekkram Bael and the child of a Noble Vampire of the Carmilla Faction, she was innately powerful. It was for that reason that Zekram Bael, his Ancestor had to intervene personally to kill her.

He gripped the handle of Blood Drinker the sword and thought about it. He had yet to meet the man, but he had only heard positive things. His Uncle, Grandfather, and even Sirzechs told him good things about the man. Feeling his doubt Vespera reached out to him through their link. 

'Whose side will you pick?' 

'Depends.' 

He pulled out another vial of his blood and poured it over the blade. He watched as it was drawn inside before thinking. 

'Who was your Mother?' 

Vespera went silent but answered. 

'I don't know.' 

Romonus raised an eyebrow as he gazed at the sword.

'You don't know?' 

'No. I was told my Mother died at childbirth and I was raised by my relatives. Raised is pushing it though.' 

He remembered how Vampires hated mixed blood even more than Devils. He did not know what they would think of a girl like Vespera born of the rape of one of their kind or was it. 

'And you killed your Father because you knew what he did or thought you did?' 

'I was told all my life by the vampires around me that he forced himself on my Mother. I felt it right for me to take vengeance, and in the end, Zekram Bael himself hunted me down, and ordered me forged into this thing.' 

She said the last part with both venom and pain. He looked at the sky while holding the large sword in his right hand. 

'What would you say if you found out you were wrong?' 

'I wouldn't know what to do with myself. It has been so long since the day he defeated me. I still remember the day I was forged you know. Having my body ripped apart for material, having my soul forged into this metal, having it chained into place.

Then sealed away to never be seen again. This sword has had 4 wielders before you all of the Bael Clan, and none ever communicated with me. In the end, I drained their lives to nothing. 

After that, I was locked away in the vaults of the Bael Clan never to be touched again until you came along.' 

"So, the chance is you were tricked into killing your Father?" 

'I rather not be the case.' 

'Try to hang in there until I can get you out or lessen your pain.' 

'The blood helps, take that as you will.' 

With that, she went dormant again because the chains on her soul tormented her constantly. Blood could only dull her pain never end it. He sighed as he returned Blood Drinker to the sheath on his hip. 

It was getting late and his family might be wondering about him. He opened another teleport circle under his feet and through the paths he knew returned to his room in a flash of light. He sighed when he was back in his room as Vespera's existence messed with him. 

He sighed as he waved his hand and changed his battle suit back to his fancy suit. Once his suit was back on he walked out of his room. When he opened the door he saw Rias about to open his door. 

Rias and Romonus locked eyes as she pulled her hand away. She looked like she was caught with a hand in the cookie jar. 

"Uhhh, mom said to check up on you?"

He snorted as he ruffled her crimson hair. 

"Really? Because it looked like you wanted to go in my room." 

She pushed his hand away and turned away from him. 

"You went into mine." 

He walked past her with his head raised high. 

"That was your fault because you never wake up. Anyway, I usually train with Souji MacGregor and Surtr every weekend sometimes more if they have free time. Tomorrow I will be seeing Souji for Sword training so wake up at 6:30 ok?" 

She nodded. 

"Ok. I need to get stronger." 

"More than you know." 

She tilted her head. 

"What do you mean?"

He smiled with a mysterious smile as he walked away. She chased after him trying to get an answer from him. 

"Come on brother, what did you mean? You said, more than you know? Why? Is Riser super strong or something?" 

"Who knows? I certainly don't." 

She reached out and pulled on his arm. 

"Brother, you always tell me everything. Why won't you? I'll do anything."

He looked down at her and smiled. 

"Anything? Are you sure?" 

She nodded. 

"Yes." 

He turned around and leaned down. 

"I will do it for a kiss on the cheek." 

She blushed a little before planting a peck on his cheek. 

"Is, that good?" 

He smiled at how cute she was becoming. In a few short years, she would go from an innocent girl to a seductive bombshell. It was almost sad. 

"You need to be stronger so you can protect yourself and everyone you care about." 

She looked confused. 

"But you and Sirzechs don't need me to protect you. You two are strong." 

"We might not always be around Rias. If that happens, it will be up to you." 

He was thinking of Trihexa because Sirzechs, Serafall, Falbium, Azazel, and many other leaders of Pantheons sealed themselves away to defeat the beast. Even then it would take centuries with all of them to seal it and he might have to go with them if he could not stop Rizevim. 

Feeling how serious he got, Rias reached out and held his arm. 

"You and Zechs aren't going anywhere right?" 

"No. Not if we can help it." 

She hugged him tight worried. 

"Why? Don't leave me behind. Don't leave me alone." 

He held her tight as he tried to appease her. 

"I won't. I am not going anywhere, you know how fast I am growing stronger. Give me another 5 years and very few beings will even be a challenge. I told you right? I will become the first Devil to become a god. Can a god of Devils allow himself to be defeated?" 

She shook her head. 

"You better not." 

She let go of him and ran off somewhere. Seeing how worried she got for him made him smile before his face turned cold. 

'Katerea Leviathan, Shalba Beelzebub, Creuserey Asmodeus, and Rizevim Lucifer. The 4 bloodlines of the Satans will be mine, I just need to push my bloodline into the Super Devil level and then ascend to godhood.' 

Seeing how strong Sirzechs was as still a 'mortal' how strong would he be as a Super Devil turned god? Regardless, that was a goal for the distant future so for now he went to meet with his parents. 

They were not worried for him as it was not uncommon for him to vanish for days in his training. He had been doing so since he was 7, so he just checked on how they were doing. His Mother Venelana as usual was either managing her husband's large harem or dealing with the business owned on Earth by the Gremory Clan. 

This time, he found her engaged in 20 different calls simultaneously as she dealt with different business decisions. She just gave him a smile which let him know she was busy so he left her be. 

His Father was in his office as well working on stacks of paperwork as the Astaroth and Phenex Clans were giving more business deals now that they were going to be married together. However, the Phenex clan was less happy than the Astaroth as Rias hated Riser. Or at the least disliked him to the point of curing his name openly. 

After a quick check up his Father also didn't have much time to talk which he was fine with. He left his parents alone and instead went back to his room where he had a few things to do. 

His training for the day was over, so he began to mess around with his hobby, alchemy. As the heir to the Clan, his connections were wide so he had endless resources to use and experiment with. 

This was both a hobby and a skill worth having which was why he spent so much time on it. Too bad he was working blind as Alchemy in this verse was limited in use. Unless he could go to China and meet with the gods who were more versed in this than anyone else. 

He shook his head as he spent the next few hours brewing different potions or poison in some cases. He would note down the diffrent results when diffrent herbs, monster body parts, poisons and venoms had when they reacted together. 

In the end, he brewed a few more Blood Resurgence Potions, and some simple healing potions. He even created a new poison which he found some use for so he noted down the recipe. 

Once he finished his brewing, he cleaned up his Alchemy set and walked to his personal bathroom. Much like everything in Devil Society it was massive as it was made with the fact that he was expected to have a Harem in the future. 

Fertility was a common issue among Devils so they made up for it with many female lovers to have a chance to produce a child. For him, it was empty as his Fiance Latia was still a new relationship. No matter how powerful or mature he was he was still 11. 

'Damn you number 11. Turn into 18 already and show me my greatness.' 

He sighed as he showered under the magical water. It nourished his skin and hair along with the body wash and shampoo made for Nobles like him. Once all the stress of the day was gone, he got dressed and returned to bed. 

Though instead of sleeping, he began to train in his Touki control and his internal Demonic Energy circulation. Using both at the same time would allow him to increase his physical abillities to new extremes. 

He did this for the next hour until he felt that it was too late. When he checked his phone, he saw that it was already 3:30 AM. It was very late and he only had 3 hours to sleep. 

That was fine as he did not need much sleep so he set his alarm and finaly fell asleep. As he slept, he healed from the stress of the day and for those three hours hew as at peace. But as he was used to just 3 hours later he was awoken at the time of training, 6:30 AM. 

He sighed as he only woke up this early on weekends. Yesterday was Friday which meant that his teachers had time to train him on a day they all had off. Today was Saturday, but he only had to train with Souji in the art of the sword today as MacGregor was off doing who knows what he did in his free time. 

Mages were kinda scary when they were focused on their reaserch and MacGregor Mathers was no exception. Regardless, he got himself dressed and went to wake up Rias who was actualy awake without him waking her up. 

She was already dressed in training clothes and he teleported back to the Capital Lilith. To avoid pissing off Grayfia, he would use a bounded Field to not damage the field again. When they arrived, Souji was already waiting.

He smiled when he saw Rias. 

"Rias, glad of you to join us again. I will teach you after I teach Romonus. In the meantime work on your control or watch us and draw inspiration." 

She nodded. 

"Yes sir." 

Souji then turned to Romonus with a calm smile. He began to draw his Katana as Romonus drew Blood Drinker. 

"Show me what you have learned." 

"Right." 

(I am not one to ask, but if it is not too much trouble a review would help a lot. Also, any recomendations for the harem. I have a few already choosen, but suggestions might give me ideas.)
