Aftermath

Once the Peace Treaty Conference was over, the Heavenly Faction and Azazel had gone back to their respective base of operations.

So, what happened next was the aftermath discussion about the alliance forged between the Three Great Faction today.

"I am speechless by what you have done." Sona sighed towards me, "Not only are you willing to let a enemy stay at your house, you also kissed the Seraph Gabriel right in front of us."

"H-Harem.." Issei gave me an intense stare.

I simply ignored him and took a deep breath to relax my emotions, "First of all, she was the one who kissed me."

"And you didn't stop, even when you have the ability to stop time." Akeno argued to my point and shot me smug grin.

'This.. Girl.' I gave her a deadpan stare, 'Sometimes I feel like simply bashing her head for making such ridiculous comments, but she always makes a solid point.'

"To be honest, I don't really care." Xenovia stated nonchalantly and placed her hand on my shoulder for support.

"Actually, you kissing Gabriel-sama and her not falling means a lot!" Irina exclaimed in an energetic tone and was almost hopping on the couch like an excited bunny.

"It means you can possibly copulate with the Pure-blood Angels and give birth to an hybrid Race." Serafall realised with her eyes going wide, "The statement I just made does not leaves this room." Serafall warned seriously when she realised how dangerous this information could be, "Do you all understand?"

Katarea who was in the room gave Serafall a vicious smirk, but I shot her a sharp glare and made her stay quiet.

I couldn't believe that this woman was actually so stupid that she trying to get herself killed, just because she wanted to humiliate a person she despised a lot. It wasn't even hatred, but just a simpleton, arrogant mindset she had.

Everybody voiced in acknowledgment to Serafall and promised her to not reveal this detail to anybody.

"We should leave now." Serafall looked at Sirzechs, "The Peace Treaty has been signed and we need to inform the other Satans and the Great King Faction about it. Not only that, our alliance needs to be made public to our people and only you are capable of doing that."

"We have to leave now?" Sirzechs whined childishly, "But we only got here!"

"Sirzechs." Serafall shot him a stern glare, because it was time to get serious.

"Alright." Sirzechs took a deep breath and stood up with his leader persona back on his face, "Katarea." He glared at the descendant of Leviathan, who had made herself comfortable on the empty couch now.

"W-What?" Katarea looked at him with a fearful expression.

"Trust me, your death won't be as quick as Creuserey if you try anything foolish in my absence." Sirzechs warned with a grave expression, "I trust my son, but its my responsibility to warn you."

"I get it." Katarea frowned back at him with an anxious sigh, "I have no interest in causing unnecessary violence, anyways."

Sirzechs nodded at the Pure-blood Devil and turned to his Queen, "Grayfia."

"I am staying." Grayfia replied with a straight face, "I can continue my duty at the Underworld from tomorrow onwards, but I'll be spending the night here."

"That's what I want you to do." Sirzechs nodded in acknowledgment and turned towards me, just to see me laying on the couch and resting my head on Sona's lap.

He sighed with a fond smile.

Meanwhile, it was a whole different matter when Serafall noticed us, "Now, its my time." I chuckled sinisterly and firmly planted my face between Sona's thighs, over her skirt.

Sona gently caressed my head with an shy expression, "Idiot." She smiled in elation and softly ruffled my hairs.

"Heaven." I turned sideways and meaningfully grinned at Serafall, "And it's just the Seventh one."

"Y-Y-You.." Serafall felt her legs lose all their strength as she looked at herself being cuckolded by her own sister. She fell forwards on the floor with the support of her arms and had an despaired look in her eyes, "M-My Sona-tan."

"Mine." I stated sweetly and rubbed my hands across her milky thighs.

"A-Alex..!" Sona blushed and slapped the back of my head, "Stop teasing her!"

"Ouch." I chuckled and continued to enjoy the blissful moment.

"I am jealous." Irina pouted with an helpless expression as she watched the intimacy between me and Sona.

"We'll extract vengeance, Irina." Xenovia stated meaningfully by placing her hand on her shoulder and glared at me, "We'll have him our own way."

"Owa, scary exorcists~" I yawned with an mischievous grin.

"Serafall." Sirzechs sighed at his fellow Maou and helped her stand up.

"Pathetic." Katarea scoffed at the Maou Leviathan.

"S-Sona-tan!" Serafall dramatically reached out her hands towards her sister, but Sirzechs held her back like as she was an problem child.

"Ara Ara~" Akeno giggled and fondly smiled at the sleeping boy on Kaichou's lap, "He's already asleep." Akeno remarked with an envious tug in her chest towards the Sitri.

"It's midnight." Grayfia reasoned with an adoring smile and sat next to the Sitri heiress, "Its already past his bedtime." She softly ruffled his hairs.

"I don't even get to say goodbye." Sirzechs regretfully dropped his head and whined childishly, "I was so looking forward to the father and son hug!"

"You're not on that level yet." Grayfia scoffed at him with an meaningful smirk, "You might've just lost another set of your teeth for trying that, so be grateful that you're lucky he's asleep."

Sirzechs pouted by narrowing his eyes at the Mama-Devil.

"We should also head back now." Rias stated when she noticed that Koneko was asleep as well, "What do you think about Gasper, Nii-sama?"

"He has a great potential for growth." Sirzechs recovered from his sorrow and nodded at his sister with a fond smile, "His Sacred Gear is one of the Unique ones, the ability to stop the time of an object or a limited space."

"Yeah, we practiced, but it's not working out for us." Rias sighed helplessly and Gasper whimpered in his box.

"Then you should try asking for Alexander's help." Sirzechs suggested, "He seems to have mastery over stopping time, so he should be able to help Gasper to dome degree."

"That's the problem." Rias grumbled and glanced at the sleeping beauty, "He won't listen to my request."

"Then try making him an deal." Sirzechs shrugged in response, "You are asking him for his help in exchange for nothing, that's not how it works."

"Is your sister really Devil?" Katarea frowned at Sirzechs by glancing at the Crimson haired bimbo, "Our Kind is all about making deals."

"You don't need to teach me how to be a Devil." Rias annoyingly frowned at the Leviathan.

"She's right, though." Sirzechs chuckled in response, "Make a deal with him."

Rias pouted with an embarrassed expression and nodded in acknowledgment, "When would I see you next?"

"Possibly, not anytime soon." Sirzechs solemnly shook his head, "The work at Underworld is only going to increase. First of all, we'll have to shut down the people who would rise against the alliance of the Three Factions."

"Out of the three, our kind is the most troublesome." Serafall snorted and gave Katarea a meaningful glare.

Katarea proudly raised her chin and turned away.

"Nee-sama." Sona approached her elder sister and stood next to Rias.

Serafall curiously looked towards the couch and saw that the brat was sleeping on his mother's lap now, 'Good for me!' She grinned viciously and rushed towards her sister, "Sona-tan!" She embraced her face into her cute little, still growing breasts.

"N-Nee-sama." Sona blushed at the gentle impact and shyly adjusted her specs.

"Sona-tan!" Serafall cried out like an degenerate, "That molestor." She glanced at the moron, "He didn't touch you too much, did he?" She asked innocently, "Do know, I'll still love you even after he has defiled your body with his touch!"

"Nee-sama." Sona glared at her sister with a straight face, "You're going a little far now."

"B-But.." Serafall sobbed helplessly, "At least, D-do use protection when you're doing it!" She stated with an heavy heart as her legs started going weak again, 'I-I can't believe I am letting someone have my Sona-tan. And what's this feeling..?' She felt the tug in her chest, 'Am I aroused by thinking that my Sona-tan is being d-defiled by that Monster?'

"Nee-sama?" Sona stared at her sister's bright red face with a perplexed scowl, "What are you thinking?" She suspiciously narrowed her eyes.

"N-Nothing.." Serafall awkwardly wiped away the drool on her mouth by using the sleeves of her dress, "You take care, okay?" She stood straight and genuinely smiled at her sister, "We'll probably meet during your vacation next time."

"I'll inform you if anything happens." Sona nodded with a responsible gleem in her eyes.

"O-One photo." Serafall turned to see Sirzechs shivering while trying to take a photo of his sleeping son.

"Damn, he's so cute." Sirzechs smiled in satisfaction after getting the picture, "Maybe, I can get a better one."

"You should leave now." Grayfia narrowed her eyes at her King.

"Ugh.." Sirzechs groaned and stepped back towards Serafall. He nodded at his fellow Maou and created a Teleportation Circle with his magic, "Take care, Rias."

"I will." Rias nodded back with a smile, before her brother and Serafall disappeared on the Magic circle.

"We should head back." Sona sighed stressfully by looking at Rias, "I can't believe the Peace Treaty was successful after all that mess."

"I share the same thoughts." Rias nodded in agreement with a tired expression.

"Buchou, Asia is also falling asleep." Issei called out with concerned expression, "Can we leave now?"

"We should." Rias nodded in acknowledgment and created a Teleportation circle for them, "It would lead you to your house, Issei."

"Thanks, Buchou." Issei nodded gratefully and stepped on the Teleportation circle with Asia in his arms.

Sona also created the Teleportation circles for her Peerage members and sent them to their respective homes as well, with the exception of Tsubaki, because they lived in the same apartment.

"Rias, we should leave as well." Akeno created a Teleportation circle while holding the sleeping Koneko in her arms, "I have sent Gasper with Yuuto to his apartment."

"That.." Sona realised the destruction that was caused at the school tonight and stressfully palmed her face, "That's going to be a trouble."

Unknown to her, the alliance of the Three Great Factions had already started working on the repairing process.

Occult Research Club was gone with the Old School Building, so Gasper no longer had a home. Rias realised, and thankfully nodded towards her Queen. She could always trust Akeno to make the right decisions.

Grayfia picked up her son in her arms and stood up from the couch, "Katarea, follow me." She stated firmly and looked at the rest of them in the room, "Irina, Xenovia, you should also get to your room."

"Are you sure?" Xenovia asked with a concerned frown and glanced at Katarea.

"Petty." Katarea scoffed as she noticed the human girl's gaze, "Do you really think I have the interest to kill you lesser beings? Don't mock me."

"Yeah, she couldn't even if she tried." Irina assured her partner Knight with an innocent smile.

Katarea growled, but didn't argue back, 'The boy wasn't kidding.' She glanced at the sleeping boy with an helpless expression.

"Come with me." Katarea heard the Maid say and she followed after her to the floor upstairs, "This is the guest room." Grayfia stated by pointing at the door, "You can stay there for now. You're held as a prisoner, but you won't be treated as one in this house, so be grateful. You want anything, you come to me or Alexander."

"Whatever." Katarea snorted in response and entered into the guest room.

'What's with these people?' Katarea closed the door behind her and turned to see the room that was provided to her. It wasn't anything special and could easily be referred to as cheap, compared to the luxuries she was used to.

The fact that astounded her the most was that she was still alive, despite facing the wrath of Sirzechs Lucifer.

She fell back on the bed and breathed heavily by covering her eyes and the top of her head, and was reminded of the absurd display of power that would've erased existence upon the slightest contact.

That was the difference between her and Maou Sirzechs Lucifer, the Strongest Devil.

'No.' Katarea realised, 'No longer the Strongest Devil.' There was a even more ridiculous person, 'Alexander.' She gulped with a terrified expression, 'That's why Ophis had warned us to stay away from the boy, we are no match for him.'

Even if she had realised this fact sooner, would the Old Satan Faction listened to her? Her opinion didn't even matter anyways, because she was pretending to be the last descendant of the Levithan Clan.

The real one, she was alive and dead at the same time. She was the only other person who carried the powers of Maou Levithan. And as her Aunt and the only family alive, it was Katarea's responsibility to protect that child and keep her away from the filthy clutches of the Old and New Satan Faction.

But, what would've have happened if she had died today? Would anyone have ever found the corpse like body of her niece?

'That boy.' Katarea anxiously clenched her fists, 'He saved my life.' She admitted, even it damaged her pride a lot, 'He's different from the people of New Satan Faction and realises what's going on around him, even if he pretends to act as a naive child.'

Katarea wondered, 'What would a person from the Old Satan Faction would've done if they could have that boy's powers?' A shivered crawled down Katarea's spine at the thought.

Even if the thought was a horrifying image in her mind, it made Katarea even more curious for why the boy named Alexander had not conquered the World yet.

Was it even worth it?
