The Epic of Leviathan (A Mutant's Ascension)

[Sitri Mansion, Kuoh Town] 

Sona took a deep breath and crawled out of her bed. Right now, she was a proud wielder of a Longinus type Scared Gear. In fact, she possessed one of the three Holy Relics, Incinerate Anthem and she was a full-fledged Devil. Sona wanted to roll her eyes at the irony of the situation. 

Sona had no idea what sort of changes Lady Hela had made, but she could comfortably use the Sacred Gear without any problems. Yes, she hasn't tried using it, but she instinctively knew that she could use the Sacred Gear without harming herself. 

Before trying out her new toy, she decided to talk with some experts. She knew that Grayfia was keeping an eye on the Heaven's System, so she decided to contact the silver-haired maid. Sona's stomach growled in protest. 

'Looks like the meeting has to wait' Sona mused as she made her way towards the washroom. Even though her body was clean, she wanted to take a bath to relax her sore body. Sona noticed that her left hand was wrapped by a bandage. 

Sona quickly unwrapped her arm only to find that her wound was healing at a visible rate. 'I was wounded by Holy Flames, so in normal conditions, it should have taken a few weeks to heal completely, but my wound is getting healed at a visible rate on its own' Sona pondered with a thoughtful look on her face.

She turned on the tap to fill the bath and turned on the shower with her other hand. After thinking for several seconds, she realized that there was only one viable conclusion. 'My wound is getting healed by my new Sacred Gear' Sona concluded. 

Yes, Asia Argento might have healed her when she was knocked out, but her wound was still healing. As much as she knew, Asia Argento didn't have the ability to heal wounds from a distance… that is why Sona decided to ignore that theory. 

After nearly an hour, Sona was about to leave her room completely dressed, but that is when someone knocked on the door. "Enter" Sona called out and the door clicked open. Tsubaki Shinra slowly entered the room with a soft smile on her face. 

"How are you feeling, Sona?" Tsubaki asked softly, there was a slight undertone of concern in her voice too. 

"I am sore" Sona deadpanned and after a few moments, she finally cracked a smile. "Besides my soreness, I am good. I am getting better as I am speaking" Sona finished with a bright smile on her face. 

"That is good I suppose, what exactly happened after you defeated that woman? For a few seconds you looked exhausted, but otherwise, you were fine, and then all of a sudden you started to scream like a banshee and moments later, you passed out after giving us a fright" Tsubaki questioned in a worried tone. 

Sona released a tired sigh. "Where are the others? I think I should tell everyone at the same time…" Sona trailed off and Tsubaki frowned, but she still agreed with Sona. 

"Most of your Peerage members are training. Rias-sama and her Peerage are also training, but they have their own regiment. Serafall-sama is resting in the next room" Tsubaki answered and Sona paled when she heard that her sister was here. 

"Oh… Grayfia-sama informed me to call her as soon as you woke up, but I decided to wait until I could confirm that you were okay with it" Tsubaki added and Sona closed her eyes and decided to count to ten. 

"Ok… so, how long have I been out?" Sona asked curiously after she was finally able to calm her nerves. 

"You have been out cold for nearly a day" Tsubaki answered and Sona choked after hearing the answer. Now she wasn't surprised that her sister was bunking in the next room, but she was surprised that she didn't wake up in the Sitri Hospital. 

"I see… but why wasn't I chucked into our family hospital?" Sona asked with a confused look on her face. 

"Well… according to the doctors you were completely fine, just magically exhausted. So, Serafall-Sama decided to keep you here, where she could constantly keep an eye on you. I had to force her to take a nap" Tsubaki answered with a grin and Sona groaned in embarrassment. 

Sona would never admit it, but she was really glad that her sister loved her so much. Both Sona and Tsubaki were pulled out of their musings when Sona's stomach growled loudly. Once again Sona started to blush, but she quickly got over it. 

"We have some food in the fridge or I could make something if you want" Tsubaki suggested. 

"Food in the fridge is good. I will help myself with the food. Why don't you call the others while I do that?" Sona asked and Tsubaki quickly nodded her head in understanding. After that, both Sona and Tsubaki walked out of the room. While Tsubaki devised to call Serafall, Sona decided to head towards the kitchen. 

Sona arrived in the kitchen and found some beef ramen inside the fridge. Beef ramen was good and Sona wasn't going to complain as she could eat a whole cow right now, but she still decided to heat up the food as she didn't want to eat cold food. 

As soon as Sona finished putting the bowl inside the microwave, she was tackled by a pink blur. Sona lost her footing and she would have ended up on the floor if the person who had assaulted her wasn't a strong person. Sona had easily figured out the identity of her assaulter due to the extremely familiar figure. 

"So-tan!! You are finally awake! I have been so worried!" Serafall exclaimed loudly and started to twirl Sona around the kitchen while sobbing. Now, Sona felt really bad for worrying her sister even though it wasn't her fault. 

So, she hugged back her sister and decided to placate her sister before the others arrived. "I am completely fine Onee-San, and I am sorry that I worried you" Sona cooed into Serafall's ear as she started to rub Serafall's back with her hands in a calming manner. 

Serafall didn't say anything else, but she started to calm down. Serafall finally separated herself from Sona so that she could look at her sister. Serafall opened her mouth to say something, but moments later, she closed her mouth as she decided to change her words. 

"You have grown so much in the past month, I can hardly recognize you anymore" Serafall said softly as she caressed Sona's cheek. Sona wanted to tell her sister that it wasn't true, but Serafall decided to continue before Sona could speak up. 

"I am so proud of you. You are finally becoming your own woman and I couldn't be any happier" Serafall cooed gently as she stared at her sister with a look of pride in her eyes. Slowly tears of happiness started to roll down from Sona's eyes and she gave her sister a tight hug. 

Both Serafall and Sona heard footsteps arriving and Sona parted from her sister and wiped off her sister. "Thank you, Onee-chan" Sona blurted out cheerfully and Serafall was very happy that Sona once again called her using 'Onee-chan'. Sona used to call her 'Onee-chan' when she was small, but it changed into 'Onee-San' as Sona grew up. 

A ding was heard from the microwave followed by the arrival of the others. Grayfia Lucifuge was also among the group, but the said woman was dutifully standing at the side, sporting her usual maidly persona. Everyone quickly greeted Sona and after a couple of minutes, Sona found herself seated at the dining table with her food. 

"So, what exactly happened after you defeated that woman named Walburga?" It was Serafall who asked the first question. 

"Everything was fine until a wisp of Purple Flames crawled out of Walburga's dead body and entered my body before I could move away" Sona answered as she picked up her chopsticks. Several gasps were heard throughout the room, but Sona's eyes were fixated on Grayfia. 

"I think Walburga's Sacred Gear was passed over to me after my death, but I don't know why or how something like that could happen" Sona said and for a few seconds, nobody said anything as they didn't even know how to react. 

"But that is not possible! Full-fledged Devils can't possess Sacred Gears, it is simply impossible!" Akeno exclaimed in surprise and Rias along with some others nodded their heads in agreement. 

"But there must be an explanation for that. It isn't widely known, but Lady Hela has conquered Heaven and she can also access the Sacred Gear System… I think she has made some changes. What can you tell us, Grayfia?" Serafall asked in a firm tone as she glanced towards Grayfia. 

After hearing Serafall's words, everyone glanced towards Grayfia. The silver-haired maid took a deep breath and she began to speak. "Yes, Lady Hela has made several changes in the Sacred Gear System and I am what Sona-sama said is true, after Walburga's death, her Sacred Gear was transferred to Sona-sama…"
