White VS Red and Chaos Is Growing.

Once everyone got done eating Azazel and Romonus spent an hour talking about Valerie's Sacred Gear. Since it was a Longinus and a Sub-Species she was bound to be a powerful individual if she didn't go insane. 

Romonus already knew what he wanted and if regular ingestion of his blood could mitigate the effects of the Sephiroth Graal he was willing to feed her often. She was going to pay him back for every drop with the powers her Sacred Gear had. 

All he had to do was give her proper guidance and she could resurrect anyone he wanted. Azazel even started to give him some advice on his current peerage as Romonus' training was near perfect. 

He still accepted anything Azazel said as he gave good advice. However, at the turn of the hour, Viviana and Itsuki were itching to fight. Everyone went outside for their spar with Azazel and Romonus watching this carefully. 

Whoever won would show who was the better trainer of talents. Romonus smirked as he raised his hand and created a massive multilayered Bounded Field with an area of 10 Football Fields. 

When it went up Azazel turned to Viviana next to him. 

"Good luck, and remember that this is a friendly spar." 

She waved him off.

"I know that Azazel, stop being a nosy butt." 

He shrugged. 

"If that is what you want." 

As for Romonus, he turned to Itsuki who was jumping in place and shadowboxing.

"Remember, you got a Pawn Piece so use its Promotion because it is your innate ability."

She nodded. 

"Right." 

Both girls stepped forward with their Sacred Gears already humming with power. Itsuki raised the Boosted Gear before her eyes began to glow a bright green. 

"Balance Breaker." 

[Welsh Dragon Scail Mail.]

In a burst of dark red dragon flames, she once again called on the Scail Mail. Azazel was honestly surprised that she had that because Viviana had it as well. 

"Wow." 

Viviana squinted her eyes as she spoke. 

"Balance Breaker." 

{Vanishing Dragon Scail Mail.}

In an eruption of blue energy, she was covered in her Scail Mail. Once both had their Sacred Gears they locked on the other. Itsuki smashed her fists together as she locked onto her rival. 

"You know, Ddraig told me that you two lost because you were weak." 

{LIES! WE LOST BECAUSE HE WAS WEAK!}

Ddraig told her to say that because it would set him off. 

[Let's let him have it. Boost. Boost. Boost. Boost. Boost. Boost. Boost. Boost. Boost. Boost.] 

Already Itsuki had boosted to over 1,000 times her original power which caused the entire Bounded Field to fill with a green glow. 

"Promotion Rook." 

When she changed into the Rook Mode her armor became thicker and her strength rose alongside the power she Boosted. She charged at full speed forward and she reached Viviana instantly. She pulled her glowing fist back and at full force punched where her rival's liver should be. 

Her first smashed through Viviana's Scail Mail like it was butter. Luckily Viviana was not a weakling and instantly used the Divide to vent some of the energy. 

{Divide, Divide, Divide, Divide, Divide, Divide.}

Itsuki's fist still connected with Viviana and thanks to the quick-paced Divides the power was lowered severely. Alongside her Satan heritage and the training she had that her liver did not burst. She was sent hurling through the air like a paper in the wind. 

She smashed into the wall of the Bounded Field leaving Azazel slack-jawed. He was both worried and impressed. He watched on as Viviana stood up with her armor cracked in several places. Albion started to repair those cracks to make her battle-ready. 

'What the fuck happened Albion?' 

{It appears that Ddraig's host is much stronger than we had expected. She is drawing more power from her Evil Piece than normal.}

Itsuki tilted her head. 

"Hey, you ok? I put quite a bit of power into that punch. It looked like it hurt." 

Viviana froze in place out of sheer rage. She bellowed to the sky which made Azazel shake his head. 

'Here we go again.' 

Enhancing her abilities with the Demonic Power of her heritage, Viviana charged forward on the Divine Dividing. Seeing that made Itsuki shrug. 

"Oh well, guess I just got to beat you unconscious."

Romonus smirked as she had taken his training well. If she and Issei fought, the latter would die because unlike him, Itsuki had talent. When the two girls reached each other, Itsuki clenched her fist and surged her Draconic Aura and Demonic Energy into her fist. 

She punched up and landed a major uppercut on Viviana, only to be kicked in the chest. 

{Divide.}

The moment she felt her energy be drained away Itsuki pulled away. 

'Ddraig, how do I avoid that?' 

[Don't touch her directly. Use a barrier of energy to avoid coming into contact with the Divine Dividing.]

'Got it. Promotion Queen.' 

Doing as she was instructed Itsuki formed a thin barrier around her body by drawing on the control the Bishop aspect of the Queen granted her. Suddenly, she avoided a punch from Viviana by ducking before kicking her in the gut.

The blow was strong enough that it sent her flying into the air. Itsuki grinned behind her helmet as she spread her arms apart. The Scail Mail warped as a pair of cannons formed on her shoulders. 

[Boost. Boost. Boost. Boost. Boost. Boost. Boost.]

"Dragon Blaster."

A massive wave of Dragon Aura and Demonic Energy moved toward Viviana in the air. Seeing the attack she shuddered as she held her hands out. Azazel moved as he was about to interfere.

However, Romonus summoned Archaon and Ruin Maker before flying into the air. He appeared between Viviana and Itsuki's Blast. 

"Sorry about this." 

He pushed her out of the way before raising his massive blade in the air before a giant pillar of purple Power of Destruction surged from the blade. He swung down against the Dragon Blaster that Itsuki used.

The blast ended up resisting a few moments before his superior power stopped and overwhelmed it. The massive wave of Destruction canceled out the Dragon Blaster which exploded with a massive wave of power. 

Everyone who was watching was left speechless by the amount of Power Itsuki could release. Romonus hefted his blade and rested it on his shoulder as he looked at Viviana. 

The poor girl was a shivering mess as that would have killed her. 

"You good kid?" 

She looked up at the armored form of Romonus before she gathered her nerves back. 

"I'm fine." 

"Sure you are. Excuse me one moment." 

Romonus stepped off the ground and landed next to Itsuki. She shuddered as she looked up at him. 

"Boss, I-" 

He just patted her shoulder as he wasn't mad. Just confused why she pulled out some of the heavy weapons.

"Why did you go all out?"

She dispelled the helmet and looked a little embarrassed. 

"I thought she could handle it. I mean, you said she was the granddaughter of Rizevim and the White Dragon Emperor. So I thought she would measure up. I was wrong." 

Romonus felt that was reasonable. 

"True. Azazel, I am truly sorry for almost getting your kid killed."

Azazel saw how Viviana landed and displaced the Balance Breaker. She was shivering both in rage at what she heard Itsuki say and the feeling of almost dying. He placed a hand on her shoulder and nodded. 

"It was an accident, but what in the hell have you been doing to train that girl? She is the same age as Viviana right?" 

Romonus turned to Itsuki who also removed the Scail Mail. He patted her head making her smile. 

"She is. As for what made her so strong, I put her through training up to my standards."

'And magic elixirs.' 

Azazel was honestly impressed.

"Whatever you did it worked." 

That reminded Romonus of something. 

"Azazel, you are a good craftsman right?" 

"I consider myself one yes?" 

Romonus now had to ask him something. 

"Alright then, would you be able to build me a Time Chamber? A place where time goes faster inside than out. I can pay for it." 

Azazel pondered on it as he never thought about it. 

"Sure, why not? What are you offering?" 

Romonus had one thing he always was open to trade. 

"I got potions I make. I am an Alchemist." 

Azazel started to think about it carefully before he nodded. 

"Got it. Just give me some time and I will give you that." 

Romonus nodded. 

"Thanks."

Azazel now looked at Viviana who was quite shaken up. 

"I will have to postpone what I had planned with Valerie for a few days. How long will you stay here?"

"1 month, I will be spending a few months in a mentorship. Then I will travel to the Country of China for a time." 

Azazel was now curious, but he didn't ask.

"That should be plenty of time. I will visit every day then to get Valerie accustomed to the Sephiroth Graal." 

Romonus nodded and watched as they teleported away. When they were gone Miria crossed her arms confused. 

"Azazel is a better character than he was described."

Romonus nodded. 

"True. My instincts said to trust him so I did. Valerie, come on. Let's see what you can do with your Sacred Gear." 

Valerie nodded as she could not be afraid of the Sephiroth Graal forever. As long as she had Romonus' blood to drink it would go better. 

"I will try." 

Romonus nodded as Archaon returned to his soul. He dispelled the Bounded Field as he walked toward the House. He didn't say more as they all went back inside.

---

Over the month, several events happened. First Romonus returned to the Bael Castle, but only to drop off Gasper and to take his room and forge room. He also told his Mother where he would be in case she wanted to visit him. 

She was sad that he would stay away, but she understood why. As for his room, after it had been plugged in the first time he made sure he could remove it at any time. 

Once he did that and Rias had Gasper he left once more to the English Safe House. Another major event was that the Ancient Enemy of the Vampires attacked the Tepes Faction.

The Werewolves attacked the now weakened Tepes faction with a bloody frenzy. They slaughtered many Nobles, Sevants, and their Thralls. Even King Tepes, Valerie's Father was slain by King Arjac the Ruler of the Werewolves. His son and Valerie's brother Marius Tepes managed to escape with a few of his trusted followers. 

As for Gasper's Father, House Vladi became turncoats and agreed to submit to Arjac's rule. This wasn't Romonus' intention, but it was a welcomed one. Now, the Carmila Faction was what remained as the survivors of the Tepes joined the Werewolves.

 Romonus paid a visit to King Arjac and offered his congratulations. The Werewolf King accepted him as a guest and Romonus revealed it had been him to assault the Vampires. King Arjac offered him any reward for the assistance, but all Romonus asked was Werewolf Venom from King Arjac himself.

The Werewolf pondered on this before he agreed to the trade. It was how Werewolves turned regular humans into Werewolves, so he handed over a large vial. However, the biggest thing was that King Arjac had asked Romonus to join them in the attack of the Carmilla Faction in a few years.

Arjac wanted to give his armies time to recover as Vampires were not easy prey. Romonus agreed, but in exchange he wanted the armies of King Arjac to help him when he started a War to take over all of Devil Society. 

The Ancient Werewolf accepted because his people loved war. With some allies secured Romonus spent the next month with Azazel visiting often to help train Valerie. Since she got to drink his blood every day her power rose rapidly and so did her mental resilience. 

Demons were mentally hardy and this was needed when training the Sephiroth Graal. They mostly experimented on small animals like bugs, rodents, and plants, but already she was making progress. 

At the rate she was going it would be a matter of time before Romonus could use the Sephiroth Graal to resurrect Aži Dahāka. If he could use the Evil Dragon as either a Sacred Gear, Famlliar, or fuse him with Archaon he could learn his forbidden Magics. 

Valerie in the Light Novel managed to make it so that Aži Dahāka could use Forbidden Magic with no cost to his Life Span. He was the 1 Evil Dragon that Romonus wanted to have on his side. 

The issue came in that resurrecting a being like Aži Dahāka would strain her heart and soul. He just hoped that when the time came she was strong enough to resist. Regardless, at the end of the month, Romonus called MacGregor who came over. 

Romonus informed him that he was ready to begin his apprenticeship under Dormuteth. Unlike what Romonus expected, he did not have to move out. He just had to go and learn under the Lich. 

MacGregor decided to take him personally to meet his former mentor.
