Solis Catastrophe II and Battle in Russia

Regina's PoV

After the fight with the exorcist girls. I along with Raina returned to Regulus Dominion. I also asked Sona to help us take a leave of absence.

Lately Akeno has been teasing me with the thing with Yuuto-kun. I forgot that they were there! It was so embarrassing just thinking back on it!

Anyway returning to the Regulus Dominion will help me escape from the constant teasing. I felt bad for Yuuto-kun though as he was also being teased.

Finally arriving at the home base, I went to find Ilya to start the creation of the upgraded version of Solis Catastrophe. So far the output of Solis Catastrophe was lesser than Regulus so I wanted to make it stronger. After all its one of my most beloved blades. A memoria from mother.

Raina went with Lily, Yun Yao, and Setanta towards Russia as it seems like they have found some of Svarog's Allies there being attacked. We have also previously made contact with them and have agreed on an alliance. As such we sent reinforcements towards them.

Currently me and Ilya are creating prototypes of Solis Catastrophe II. So far the prototypes are far from Satisfactory as they lacked the core from the original.

Solis Catastrophe is said to be forged using the power of a star. In its core was a dying star that was sealed the moment it was about to explode. This same core is where Solis Catastrophe's Flames originate.

When the sword was forged most of the power in the core remained sealed and cannot be accessed due to the sword not being able to handle the power, as such there were several seals put in place. What our goal is to create a new vessel that can handle all that power. If we are successful we could create a sword that can potentially rival the holy king sword Caliburn.

Although we have already created the design for the new weapon it is up to us to be able to create make it a reality using our skills and abilities.

Raina's PoV

Me and my party are currently in Russia assisting the retreat of allied rebel forces. The ones who came with me are Yun Yao, Lily, and Setanta.

We have already reunited with our comrades, Alyssa and Kuromi that were stationed here.

Alyssa and Kuromi were the ones that remained here after Lily returned back to base. Kuromi is technically Shiro's 3rd older sister. The 3rd living weapon created by Regulus Dominion.

A living weapon that was created earlier that Shiro. She also possessed to transform her body into various weapons. However unlike Shiro she specializes in close combat. She usually transforms her hands into giant metalic fists and hits her enemies with them. We integrated the bloodline of a dragon within her further increasing her defense, strength and power. She also has the power to control gravity as we put a magic item while creating her.

Alyssa is an illegitimate child of the Pendragon Family. She does not know of  her Father's true identity and only later found out about her heritage due to her amulet with the Pendragon Family's symbol. She is similar to me and big sister as she also never met her Father and only has an amulet which confirmed his identity. Her goal currently is to find her Father and reunite with him and ask why he left her and her mother. We met her during one of our trips to the UK and took her in after her mother died of illness.

With the exception of Ilya, she is one of the most well-known members of Regulus Dominion being titled by others as [Knight Princess].

In front of us are the various forces of the Veles Faction. We are currently outnumbered as our allies were taken by surprise when they attacked.

"Die rebels!" An enemy yelled out as they used Slavic Magic towards our escaping forces.

"Alyssa!" I yelled out towards Alyssa as she raised her empty left hand.

"Come! [Prydwen!]" A holy shield materialises in her left hand as she projects it to guard our retreating forces.

Lily then fired devil magic towards the enemies and killed several of them.

"Damn this is endless..." Lily cursed out seeing the remaining enemy numbers.

Yun Yao is already in her balance breaker form and is rampaging across the battlefield with Kuromi trying to lessen the enemy numbers while protecting the escaping allies.

Me, Alyssa, Lilynee-chan and Setanta remained in the front lines along with several of our allies to cover for the majority of our forces.

As we were fighting in the front lines I suddenly heard a voice from one of our allies.

"Lady Raina most of the forces have already retreated it is now time to go!" Said one of the leaders of the resistance through the communication device in my ear.

Hearing this I smiled and turned towards Alyssa.

"Alyssa, Break open a path for retreat!" Hearing me Alyssa nodded as she raised her holy sword in the air and started charging holy power.

I then turned towards the captain of the elite squad that are stalling with us.

"Uncle Alex, Its time to retreat!" Hearing me he nodded and sounded the signal for retreat.

"Yun Yao! Kuromi!" I called out to the two of them who were rampaging across the battlefield.

It was at this moment that Alyssa notified me that she finished charging up for an attack.

"Raina its ready!"

"Do it we are ready!" I yelled out as I hear that.

"[Neo-Excalibur!]" Alyssa yelled out in response as a beam of golden light pierced through and greated an opening for us to escape which we immediately ran through and escaped.

Neo-Excalibur is Alyssa's main weapon. It is a sword that we created based on the True Excalibur in Onee-chan's treasury.

After opening a path we immediately ran and retreated from the area.

We have successfully done it...

Looking at the sword in front of us we can feel a strong aura that it releases.

We have already done some testing earlier. The power of the flames were even stronger than before and made it harder to control. I can also now unleash an attack similar to the True Balmung as when I fought Onii-chan.

To the side Ilya also lets out a smile at our success.

"We finally did it... That was so exhausting." I said remembering how hard it was to forge this sword.

"Well we are lucky we manged it in just a few days." Replied Ilya as we sat in the training grounds.

We have just finished testing out Solis Catastrophe II and the results were satisfactory.

"Im really thankful for that..." I said then turned to her and continued, "is it really ok to help me instead of training your new Regalia?"

I asked her since it hasn't been long since they have created it.

"Hmm? I have already gotten used to it for the most part. Just needs some time before I can perfectly use it." She replied.

"You really adapt fast... Well I guess I'll also need to retrain the use of Solis Catastrophe to get used to controlling the improved output." I said with a smile as I look into my beloved weapon.

"Ah right! Raina and the others have already stabilized the situation in Russia. They contacted me as you were testing out Solis Catastrophe II."

"When are they coming back?"

"Later or tomorrow depending if there are any problems."

As we were talking the communication device I gave to Father has started ringing. Seeing this Ilya gave a nod as I picked up.

"Hello, Father you need anything?"

"It seems that Kokabiel has started his plans of trying to start another war. Currently the devils are fighting them in your school."

"What?!" I asked out in shock. I didn't think that Kokabiel would move that fast.

"Don't worry I have already sent Vali to retrieve him so your friends should be fine."

"Father! Have you forgotten?! The Red Dragon Emperor is there!" I yelled out hearing that. According to legend the Red and White Heavenly Dragons would always fight whenever they meet each other.

Im worried for Issei and the others as he currently won't be able to face Onii-chan in battle.

"I have already warned him to avoid fighting Issei so dont worry too much."

"Wait Issei? You have met him before?" I asked him as we haven't told him the Red Dragon Emperor's name yet nor did he ask us.

"Yeah I summoned him a few times. He was pretty fun to hang out with." Hearing that my cheek twitched a bit as Im sure Rias would be pissed hearing this.

"Wait enough of that! Do you really think Onii-chan would listen to you after hearing that his rival is there?" I asked him suddenly remembering the problem.

"..." Hearing that he was quiet for a bit before responding, "...but wouldn't he not choose to fight a weak opponent?" He said weakly.

"Are you sure? For all we know he could think of pushing Issei to try harder and lead to a fight. Should the situation get desperate Ddraig would forcibly change Issei's body just to survive."

"..."

"I'll go. Just in case." I said with a sigh.

After hanging up with Father I turned to Ilya and explained the situation before changing clothes and going to Kuon Academy.
