The Day After the Battle:

Training Grounds, Azathoth Manor:

Isaiah's POV:

"This is awesome." I muttered with a look of awe on my face as I easily created the blades of Sword Birth's X-Side Balance Breaker with a mere thought, not feeling the usual strain that I would when I previously used them.

"I said it once and I'll say it again. You are a very lucky man." Mel grumbled and I chuckled as I nodded, not disagreeing with his words at all as I knew the chances of having the Jesus unlocking the seals keeping my Sacred Gears from combining were astronomically low and yet it appears that Lady Luck has shone her grace upon me once more.

'And here I thought I would have to wait for a few more years before being able to do this.' I thought with an excited smirk as I clenched my fist, grinning at the sight of the dark grey Holy-Demonic aura coating my fist as well as the trio of blade tips poking out from in between my knuckles.

An explosion off to the side knocked me out of my excitement as I shook my head with a smile and dismissed the aura, turning to the side to see Samson lying on the ground with a grumble while five different blades that all exuded demonic power laid scattered on the ground around him.

"How's the taming going, Samson?" I asked as I walked over, watching in amusement as the man grumbled under his breath while pushing himself to his feet.

"As well as you can think, Boss. They all work well together except for when I pick Gram up. Then, it wants to be the only blade that I can wield while also forcibly making me release it. That and it keeps on telling me that I'm not worthy." I listened to Samson's grumbling as I walked over to the crimson & gold blade lying on the ground, looking down at it while also ignoring the absurd amount of pure malice trying to push itself into my mind.

'Mel?'

"Oh yeah, it's definitely feeling you out and determining if you're strong enough to wield it. It wants to see if you have what it takes to take upon the original Sigurd's title of 'Demonic Emperor.'" I frowned at that as I reached down and wrapped my fingers around the hilt, my eyes widening as the malicious aura of the blade increased exponentially while the other four blades all also released their auras at full.

It felt as if I was in the presence of five demons, all five staring me down and judging my every movement before I shook myself from my shock as I frowned and released my own aura.

The air shook as my full demonic aura clashed against the five blades', Samson grunting as he was pushed back while the four other demonic blades quickly retracted their own auras.

Gram on the other hand had a sense of excitement and anticipation running through it before I gritted my teeth as its aura increased tenfold, making it feel as if a mountain was trying to push me into the ground.

Yet, I persevered as I continued releasing my aura to try and counteract its own, every second that passed feeling like hours before I gasped as the blade finally retracted its malice, a sense of satisfaction and acknowledgement running through it as it calmed down while I fell to the ground on my ass.

'I was never even close to being able to create blades on its level, huh Mel?'

"Not a single bit. Damn, its aura was enough to make even the mindscape crack." Considering the fact that only Cu's Gae Bulg was strong enough to cause that much damage, that said a lot for both how powerful the spear was and for how powerful the Strongest Demonic Blade truly was.

"…So?" I heard Samson ask and looked up to see him looking at me, the other four blades already sheathed on his new belt for the four demonic blades & his two cleavers. I sighed as I stood up, picking up Gram with relative ease compared to earlier as I frowned.

"It appears the blade has taken some sort of liking to me. Want to see if you can hold it?" I asked, snorting as the man just gave me a smirk.

"And risk having it burn my hand off? No thank you. You can have it for yourself." I just shrugged as I created a dull & hollow sword at my side before sheathing Gram inside of it, the Demonic Power Dampening runes I traced on the new sheath suppressing most of the demonic blade's power as I rested my hand on its hilt to stop the blade from destroying the sword around it.

Chuckling as I felt the sword's reluctant agreement to keep itself suppressed, I rolled my shoulders before shaking my head at the giggles behind me while ignoring Samson's snickering form walking away.

"Man, you can just see yourself taking a bite out of those buns, can't you?"

"Indeed, but Isa is an ass-man himself and he can eat one just as good."

"Oh, what I wouldn't give to have him putting a few babies inside of me right now."

"We should be keeping this kind of talk to the bedroom lest we plant vulgar ideas in the minds of our fellow devils." Thank the Satans that Tsubaki was the voice of reasoning of the group as I gave her a thankful smile, shaking my head at the sight of Akeno, Kuroka and the new addition of Serafall all whining in disappointment as I walked over to them.

Yeah, after the meeting, the Satan Leviathan had managed to get all three of the girls to agree to giving her a 'trial run' at being part of the Azathoth Harem.

Could I do anything about it? Unless I wanted Holy Lightning, Purifying Flames, Holy Fire and Demonic Ice fired at me, I decided to just keep my mouth shut and take it on the chin.

Besides, getting the three stooges back with a few activities in the bedroom was a much better way of venting my anger and frustration.

Was Serafall pissed at the fact that I could make runes powerful enough to keep her from joining? Indeed, she was, but an agreement to a date was enough to calm her down while also making her giddy at what could happen after the date.

However, that didn't stop her from flashing me every chance she could get the moment only I was in the vicinity and let me tell you.

The woman did not like wearing any sort of underwear at all.

"Come on, Tsu~ You must be just as horny as us, right?"

"My sin is Envy, not Lust like you three."

"And I'm glad for you being the voice of reasoning every day." I said with a smile as I gave her a kiss on the forehead, making her giggle before I rolled my eyes as the other three gave me pleading pouts.

Walking around Tsubaki's sunbathing chair, I gave both the giddy Akeno and Kuroka a kiss on the forehead before I rose an eyebrow at Serafall waiting eagerly for hers.

"…You do realize that you becoming a part of this harem just puts a bigger target on my back, right?"

"Eh, nothing you're not used to." She answered with a shrug and I just nodded in agreement before she gave a muffled squeal as I leaned down and gave her a soft kiss on the cheek just barely missing her lips.

"Hey! Why does she get a cheek one and we don't?"

"You three gets to sleep with me while she doesn't."

"…Touche." Akeno nodded and I shook my head before I blinked at the sounds of explosion echoing across the vast backyard that we all called the Azathoth training ground.

Watching as Saji landed with a groan on his back, I looked over and saw Issei limping over while humming at the Vanishing Gear on his right hand & the Boosted Gear on his left hand.

(To see a partner of my own being able to keep up with the Red Dragon Emperor is quite the treat.) I heard Vritra said in a proud tone and smirked as I saw Saji just grumbling while he pushed himself up to his feet, nodding in thanks at Issei as the Pawn helped him up before the duo limped over & fell face first into the ground in front of Val.

The sunbathing Dhampir just sighed as she opened her eyes, splashing a few drops of Sephiroth Graal's white ichor onto the boys and going back to her sunbathing as the two snoring boys' wounds were quickly being healed.

"Samson?"

"On it." Samson said with a nod and I smiled & nodded as the man picked up Issei before both he and I blinked in surprise as Meredith picked up Saji, with me shrugging as he gave me a questioning glance before he shrugged as the both of them walked into the manor while carrying the two boys to their rooms.

"You guys have any idea what that was about?"

"Oh, she has a crush on him."

"…Huh?" I asked, thinking that my hearing was failing me, but the four girls just giggled as I sighed before Mel spoke.

"You all are supposed to go to the Underworld in a week from today, right? Remember to ask Sirzechs for that training."

'Ah, right. I completely forgot about that.'

"Well, if you'll excuse me, ladies. I have a bit of urgent business to attend to and take a shower if I can."

"What kind of business?" Kuroka asked with a raised eyebrow, to which I raised one back.

"The kind that will determine if I can get strong enough to fight Cao Cao with ease. I'll see you ladies at breakfast and give me five minutes alone in the shower before you join me." I said resolutely, watching as all four gave me a small pout before they nodded in acceptance and I smiled in thanks as I turned and walked into the manor. A communication crest quickly appeared on the back of my hand as I walked through the Manor's hallways, reaching my room just in time as the call connected.

"Hey, Isa! You're not one to call and we saw each other yesterday so you're definitely not missing me."

"Not at all. I was just wondering if I could ask a favour."

"Sure. I don't have anything better to do ah-! Apart from doing my work, right Fia-chan?" He said and I smirked as I had heard Grayfia smacking him across the back of his head as well as his slight yelp.

"Well, I was wondering if you would be able to help me achieve my True Form later this week as well as give Okita & MacGregor off-time so that they could help me relearn every single thing they taught me."

"…I see you've realized how dull you've become, huh?" Sirzechs said and I sighed as I realized that he would have definitely noticed.

One could call it becoming mature and realizing that there was more to life than killing, but in my quest to gain power, I realized yesterday that I had forgotten Okita's rules to being a Knight.

Never let your guard down.

Leave your honour for duels.

Be quiet and efficient.

Kill your opponent as fast as you can.

Do not grant them mercy.

Ever since I returned from my training with Buddha, I've become far stronger than before, but in return, I've forgotten what it means to be a Knight and that was something I couldn't have.

Losing to Cao Cao has shown me that I've forgotten how much stronger the beings on this world are compared to their canon counterparts thanks to my interactions in destabilizing the timelines and I refuse for someone I care for to get hurt again because of my ignorance.

"Yeah, I need to go back to my roots. Figure out who Isaiah Azathoth truly was, is and will be."

"Hahaha! Well, then. I'll figure out something, but remember. I only know the training methods that my mother used to train and as Rias can attest, it is not for the faint of heart." I still remember the times when we were younger before I left the Underworld on that training trip where Rias was too sore to move a muscle after a practical training session with Venelana.

Yet, all of those memories of her pain and exhaustion just sent a feeling of giddiness and anticipation through my body as I chuckled.

"Sounds fun. Then, I'll see you in a week's time."

"Of course! See you in a week." And as Sirzechs disconnected, I grinned widely as I walked into the bathroom, sighing in relief as I walked over to the giant shower before I began washing off all of the grime and filth before I went into the bath.

One Week Later:

Underworld Express Station:

"Wait, why are we taking the train?" Issei asked with a frown, with Saji and Meredith nodding along with him, and I chuckled as Rias shook her head.

"Since you three as well as Asia is not registered with the Underworld's Teleportation System, we are not allowed to teleport into the Underworld as the government can give us a fine for that. Therefore, we have to take the train to the station near the Gremory Castle as you will be registered to the System the moment you enter the Underworld through the official means."

"I see." Both Meredith and Saji muttered in unison with nods, Issei just nodding as I snorted before I turned as the crimson train that is the Gremory Bullet pulled into the station slowly.

"Woah, the Boss' Boss is rich-rich." Issei muttered to Saji, who nodded as the boys gave the gold & crimson luxurious train a look of awe while I shook my head as Rias giggled.

"I'll see you guys at the station. We'll be taking one of the carts behind."

"Okay."

"No fondling or groping without me." Akeno said with a glare aimed at Kuroka, who just giggled mischievously before she yelped as I chopped her softly on the head.

"Don't worry. I'll make sure she won't." Akeno just smiled as she nodded before she turned and followed Rias into one of the compartments near the front of the train, Asia, Koneko and Gasper following after them while waving at my peerage and I.

"Okay, come on everyone and make yourself comfortable. It's a 30 minute ride home and another ten minute carriage ride to the Gremory Territory."

"At least I brought my Gameboy." Saji muttered with a sigh and I chuckled as Kuroka wrapped an arm around my own, watching as the rest of the peerage boarded the train before Kuroka gave me a smile and I nodded as we walked on board.

A/N: And there we are! A quick chapter on the aftermath of the story and the set-up for the next arc!

Next chapter, back in the Underworld and training begins! I also know that there are going to be those that feel like having Isaiah in the Youth Devil Tournament is cheap since he along with the rest of the Gremory peerage should be able to take anyone out with ease, but do not worry!

Hehehe…I have something special planned there.

As always, read, enjoy, review and until the next one…

Ba-Bye~!
