The Epic of Leviathan (A Mutant's Ascension)

[7th Heaven] 

Grayfia Lucifuge was sipping tea with a calm look on her face while her gaze was fixated on the massive screen in front of her. Even though Grayfia couldn't make any changes to the Heaven's System, she could still operate it. 

Grayfia Lucifuge had been contemplating how much her life had changed since the arrival of the Destroyer. During the Civil War, she had betrayed the Old Satan Faction for the betterment of the Underworld, but her sacrifice had been useless. 

Previously Devils were ruled by the four Satan Kings, so after the end of the War, a Council was formed. Unfortunately, the Council was corrupted to the core, so at the end of the day, they were causing more damage. 

At first, Grayfia wasn't happy by the arrival of The Destroyer and his outrageous demands. Then she was handed over to the most murderous woman, by that time, Grayfia was really worried about her future, but surprisingly everything turned out for the better. 

Lady Hela might be a murderous maniac, but she was doing a lot of good. That is why she decided to keep serving Lady Hela, but she also wanted to thank The Destroyer, if he hadn't asked Lady Hela to take over the Devils, then their society wouldn't have been improving. 

Grayfia released a tired sigh… Diehauser Belial had informed her that Rias Gremory was going to visit Kuoh Town. Grayfia didn't know what to think about this development. Well, as long as the dumb bint can refrain from causing trouble, she was fine with it. 

Grayfia almost palmed her face when she found that Hexennacht was also planning to attack today. She knew that Ddraig was lazing on the roof, so she wasn't overly worried. She also knew that the said Dragon was extremely lazy, so she couldn't depend on him. 

For now, Grayfia decided to sit back and watch. Sona and her Peerage were getting trained by Yachiru Unohana, so she wanted to see how much Sona and her Peerage members had improved. 

So, Grayfia finally turned on the recording function as soon as Sona decided to confront the leader of the group. Grayfia was pretty sure that both Lady-Hela and Unohana-Sama would want to watch the fight, she was a dutiful maid, so she wasn't going to disappoint them. 

Grayfia quickly opened the file of Walburga on the Heaven's System and her eyes grew wide in surprise. Not only was the woman an extremely strong Magician, but she also possessed the Longinus, Incinerate Anthem. 

It was one of the three Holy Relics, so Walburga was going to have a huge advantage over the Devils from the beginning. Now, Grayfia was somewhat worried, but she decided to wait and see for now…

[Kuoh Town] 

Meanwhile, Walburga was gritting her teeth in anger. Firstly, someone had given her fake information. According to her information, Sona Sitri was barely a high-class Devil, but right now, her power was almost reaching Ultimate-Class level. 

Walburga wasn't at the Ultimate-Class level, but she could easily fight against Ultimate-Class enemies. There was a reason why she was considered one of the most dangerous enemies. Her Scared Gear, Incinerate Anthem was a massive advantage over Devil opponents. 

Secondly, the Sitri bitch was making her look bad in front of her group. That was something unacceptable, and the Sitri bitch was really strong. She had to fight the girl on her own. She wasn't averse to fighting or anything, but their power levels were surprising, she was averse to surprises. 

"Looks like you have been hiding your strength" Walburga commented and Sona simply smirked. 

"Well, a woman likes to keep her secrets" Sona answered with a smirk. She lifted her hands and several Magical Circles formed in front of her hand, and she launched multiple attacks towards the Magicians. Sona intentionally spread out her attacks.

Walburga was obviously a more experienced Magician, she easily countered all the attacks. She easily noticed that Sona was concentrating her attacks in a single direction. Walburga gritted her teeth in anger, if she didn't neutralize the attacks then her members would be killed by some random attacks. 

Unfortunately, that wasn't Sona's intention. She was simply keeping Walburga's attention on her. The woman was an extremely strong Magician and only Tsubaki would be able to fight the woman beside herself and by doing this, she was allowing her Peerage members to act more freely. 

Tsubaki didn't miss the chance, as soon as she saw that Sona was keeping the enemy leader busy, she decided to commence their own attacks. She gave a nod while looking towards her fellow Peerage members and all of them started to attack the Magicians. 

Momo Hanakai and Reya Kusaka started to use area of effect attacks. They wanted to take out as many enemies as quickly as possible. Several explosions rang throughout the area followed by several anguished screams.

A lot of Magicians screamed in rage and tried to attack Sona's Bishops, but most of them were cut down by Tomoe Meguri and the rest of them were squashed by Tsubasa Yura. Sona's Knight and Rook were easily working in perfect tandem to protect the Bishops. 

"Promotion, Queen!!" Genshirou Saji promoted himself to Queen and started to attack the Magicians with a pair of swords. He wasn't good with swords like Tomoe Meguri, but he was good enough to kill the Magicians. 

Tsubaki Shinra was also doing the same, but she was supporting Saji with her Magic instead of using her Sacred Gear or Naginata. Tsubaki Shinra was a better swordswoman without any doubts, but her support Magic was the best among the group. 

With Tsubaki's support Magic, Saji was able to become her equal on the battlefield even without using his Sacred Gear. Yachiru Unohana didn't know anything about Sacred Gears, that is why they haven't made much progress with them, but even without their Scared Gears, they could easily dispose of the enemies. 

Rias and her group were watching the massacre with a look of disbelief on their faces. They simply couldn't believe what was happening right in front of their eyes. Only a month ago, this would have been something completely impossible, Rias had no idea what type of training Sona's Peerage was going through. 

"Buchou! I am going to help them" Shirone said with an indifferent look on her face. 

"No!" Rias immediately refused. She didn't want her cute little Rook to get hurt. This fight was way out of their leagues. Yes, she felt useless and weak, but she had already lost one of her Peerage members in a situation like this, there was no chance in hell that she would lose another member due to foolishness. 

"I wasn't asking you" Shirone said and two white fluffy ears popped out on her head while two white tails came out of her back and she lunged towards the nearest group of Magicians before Rias could say anything. 

Shirone landed a dropkick over the place where the Magicians had been standing, creating a massive spiderweb-like cracks on the ground. The Magicians were flung around due to the force of the blow. Though Shirone didn't stand around to see the devastation, she decided to move on and continue decimating the Magicians. 

"Koneko!! I order you to come back here, right now!!" Rias screamed hysterically, but Akeno grabbed her hand to stop her from lunging at the battlefield. Obviously, Shirone decided to ignore her. 

"Rias, she is strong. Allow her to do what she wants, it is clear that she is much stronger than all of us" Akeno pointed out with a complicated look on her face. 

"No! I won't allow her to die because of her foolishness!" Rias protested and once this time Yuuto Kiba also came forward. 

"If you do that then you will simply make her hate you. Don't you see that she wants to fight and she is much stronger than those Magicians? You can't keep holding her back" Kiba said hurriedly. He didn't want Rias to make a mistake. 

"Fine!!" Rias decided to relent, but she decided that she was going to punish Koneko for insubordination. 

"Saji, cover Shirone's back!" Tsubaki's voice was heard from the battlefield, and Saji followed the order without missing a beat. A Knight with a Rook combination could be devastating on a battlefield. Even though Saji was promoted to Queen and right now, he was using his abilities to work as a Knight. 

"No!!" Walburga screeched in anger when she saw that her group was being massacred by a bunch of Devils. Some of them were crying for help, but Walburga was in a position to help them. 

"I feel insulted that you are looking away from me…" Sona said in a mocking tone and increased the speed of her attacks. Walburga gritted her teeth in anger. She was going to make that little bitch pay. 

Purple flames burst out of Walburga's hands. Sona's eyes grew wide and she jumped back to dodge those flames. She instantly recognized the Holy aura of the flames. Sona cursed inside her mind, the woman possessed a Holy Sacred Gear, but she didn't know the name of the abilities of the said Sacred Gear other than Purple Holy Flames. 

"I am going to make you pay, you bitch. Then I am going to roast your friends while laughing!!" Walburga spat out with gritted teeth and the surroundings were engulfed by Purple Flames…
