"EH!?! HOW!?!" Shouted Serafall, Gabriel had a drop of sweat running down their face. They underestimated Sethanels genius it seems.
"It was really hard ya know digging into Katerea's genetics to be able to pull this off. Luckily I knew pretty much almost everything about genetics to be able to drag out clan traits." Said Seth with a cheeky grin as he took a biscuit and ate it.
"Wait, can you awaken any other devil's clan trait like that?" Serafall asked an usual serious expression was on her face.
"Yeah probably I'd have to take a look at their genetic makeup but my AI can scan their bodies and the process might take a while." Seth answered.
The Leviathan pursed her lips, things just got a lot more complicated it seems she'll have to protect Seth secrets.
"Hey Sera wanna fight?" Asked Seth as he leaned in his chair while resting his hands behind his head.
"Seth-chan?" Serafall had a confused expression on her face as Seth got up.
"Koneko if you need me I'll be in the lab!" He shouts before motioning. "Follow me, you can come too Gabby."
Walking into a completely blank room Serafall and Gabriel looked around.
"This is like a deactivated Rating Game field." She honestly couldn't see the difference Seth nodded.
"Yep I thought I made my own right from scratch!" He said with a smile, Serafall couldn't help but smile defeatedly.
'This kid is just insane! He's like a baby Ajuka, with a bit of my personality.' thought the Satan of Foreign Affairs.
"Anyway you see Sera, what's different from Ajuka's is that mine can do this!" The field changed and it showed a giant monster fighting with sharp fangs and claws.
"By the order of justice I shall defeat you!" Shouted a copy of Sona in blue magical girls clothes with a blue stick in tow.
She fired off a blue sparkling beam of energy from said stick which destroyed the entire monster.
"So whaddya think?"
Serafall's head hung low until her body began to shake.
"SETH-CHAN YOU HAVE TO SHOW ME THAT AGAIN!!" she screamed as she ran up to him.
"Sure, I heard you had a magical show and I really wanna be in it! Can I? And I also wanna fight you. Can I?"
"Sure!" She really missed her Sonaium due to giving her some space, she's kept a respectable distance and slowly but surely they're relationship has improved a tad. So seeing Sona dressed in a magical girl outfit really sent her over the edge.
SHE NEEDED MORE OF THAT!
"Aight then now let's fight. You wanna Gabby?" He asked Gabriel.
"Oh no! Though I do have something to give you." Seth raised an eyebrow Gabriel then summoned down a sword which shined brightly with a golden glow.
"As a gift Heaven would like to give you Excalibur." Said the Seraph with a practically glowing smile.
"I don't want it." He denied it.
Surprising both devil and angel alike.
"May I ask why?" Said Gabriel as she turned her head away. She wasn't insulted, just genuinely confused.
"I got a way better sword than that broken up junk. Lemme show ya."
He took out a necklace in the shape of a transparent blue shark with bubbles seemingly inside of it.
*BOOOOOOOOMMMM!!!*
As the sword changed shape the purest most powerful Holy aura rivalling that of Gabriel's father's, her eyes widened.
"This is my Holy Sword Brotherhood!"
__________
She has gotten stronger, she flexed her demonic power. Training was a slow process but she's now seeing the results.
After her defeat by the magician she decided to take his advice. It raised many eyebrows especially from her fellow original Satans.
She looked at herself in the mirror. Her body was more toned, not overly muscular, her demonic power had also grown by a bit, throwing herself into this forest of beasts is beggining to show results.
She smiled, maybe hard work should be something devils of her class should take up on.
He was right she did have an amazing amount of potential, maybe she should see him again
She felt a warm sensation in her chest as her face got a blush.
No! Not yet! She'll get stronger and give him the best fight he'd ever ask for then she'll make him hers!
She licked her lips.
"Sethy I'm coming for you!♥️"

"You ready Sera?" asked Seth with a battle hungry smile on his face. The location of the simulated dimension was now a barren wasteland.
Serafall smiled and nodded confidently, Gabriel stood to the side deciding to stay out of the fight.
"Let the good hands commence!"Seth covered his body and sword with Touki, surprising the angel and devil duo, then dashed towards his devil opponent.
Serafall flew into the sky while peppering Seth with hundreds of ice beams and constructs. The holy aura radiating from the sword tickled her skin with stings the moment his battle intent rose.
She's not going to hold back!
Seth smiled as he activated his flight spell and flew towards her dodging all the ice beams and weapons.
He swung his sword a large but thin and sharp wave of highly-pressurised water flew towards Serafall, her instincts screamed for her to dodge which she did.
The mountains a bit back were sliced cleanly in half.
"Hehehe! This sword isn't just some random super powerful holy sword it can manipulate water aka I can make holy water! [Hydro Sonic Slicer!]"
His body became a blur, causing Serafall to set up a barrier, as he delivered a number of high speed water slashes.
The slashes became visible lines counting in the hundreds of thousands.
'This kid is way stronger than I originally thought. I seriously want him in my peerage now!' she smiled as she decided to get truly serious!
Serafall then raised her right hand and her demonic power rose as the very air became frozen. "[Cross Celsius Trigger!]"
"Oh shit!" Shouted Seth, he immediately covered himself in a [Reflega] barrier.
With that the barren wasteland became a winter wonderland.
"Wow what's that barrier made of?!" Thought Serafall as she looked at the smiling Seth who was rotating his neck.
"Alright Sera, let's get serious!" He shouts as a deep blue and golden aura surrounds his sword and body.
"Let's go baby [Holy Sword Activate!]"
The glowing sparks of holy energy and bubbles surrounded his body as did his armour. The holy energy was so much Serafall could feel her skin burning yet she couldn't help but be dazed by the beauty of Seth's armour.
Watching from afar Gabriel's mouth hung open as she clasped her hands, tears flowing down cheeks.
"Father, have you truly returned?" She looked at Seth. "If not, then is this boy a gift to us?"
"C'mon Sera, step it up!" He dashed towards Serafal, she snapped out of her daze and got ready.
She backed away and fired off a number [Cross Celsius Trigger!] at Seth. Who dodged, manoeuvred and sliced his way through her frozen attacks with a swing of his arms.
'This kid is no normal pushover. I can see why he's so open with the crazy stuff he made! He's confident in protecting himself!' she thinks as she dodges a sword beam fired from his hand and blocks one with a barrier of ice.
'Okay this kid is no joke! I'll seriously have to go at him with the intention to kill if I'm going to lose. Maybe I should call this off? No! I can't lose! I might never get to see magical girl Sona ever again!'
Responding to her emotions her demonic power grew, her determination to see her Sona in a cute magical girl costume.
"FOR MAGICAL GIRL SONA!!!"
"[Holy Sword Manifestation!]" A gigantic yet beautiful sparkling sword which had transparent colour appeared. It had the engraving of seven warriors fighting against a whale-like monster on it with a youth who seemed to be wielding brotherhood.
The sword floated behind Seth who then swung his arm forward as Serafall fired a gigantic frozen wave of demonic power at Seth.
The two attacks met Serafall's frozen beam being sliced in two, however the sword stayed put struggling to move as Serafall tried freezing it.
"Oh no you don't! [Holy Sword Tower!]"
An immense amount of Holy aura from the sword began glowing, fighting off Serafall's demonic power as the sword shifted into a tower of blades, the azured armoured gamer then as it flew down towards her.
"Kyaaaaa!!!" She screamed as it struck her, sending her flying.
"Oh shit!" Seth teleported behind and caught her casting a healing spell on her.
"Hey Sera you okay?" Seth asked her with a bright grin on his face.
As the Leviathan came to, she looked at the smiling teen as a small blush came over her face.
'So handsome!' He looked like a prince at that moment.
"Hey Sera…"
"Y-yes!"
"Wanna fight again?"
