A Month Later(Month 7, Year 1):

3rd Person POV:

"I suppose we can move to a new territory now?" MacGregor asked and Okita sighed as he nodded, both of them looking down at where Isaiah and Bardou were facing off against a monstrous swarm of bees, wasps, spiders, dragonflies & mosquitoes. It wouldn't have been such a big problem if not for the fact that each one of them was as large as a pony and they numbered in the hundreds of thousands.

You would think that they would've been a lot more worried for Isaiah and his familiar if not for the fact that the monsters didn't even get a chance to get near them. They were either burned by Bardou's bright purple flames or completely and utterly vaporized by Isaiah's lightning arrows.

He has started using his bow when he discovered his long-range weakness after Agrukk made good on his promise to kill them if they were still in his territory after the day was over. He ordered his hounds to bombard their location with fireballs from a kilometre or so away, so MacGregor and Okita had no choice but to teleport them to the New Satan Faction territory, where they let him rest before sending him out to the territory of Anubue the Chimera, the familiar of the first Satan Beelzebub.

The monstrous Fly-Lion-Wasp chimera was more than happy to let Isaiah stay in his territory in exchange for Isaiah providing him with some entertainment, i.e. fighting a few hundred thousand insects whenever he felt like it. You would have think he would be more protective of his progeny if not for the fact that Anubue can change his gender at will and produce tens of thousands of children in the span of a few hours.

"I suppose it's time anyway. Anubue might decide to change his mind one day and release a torrent of toxic gas all over his territory." Okita muttered before they teleported to the ground just as Isaiah and Bardou finished off the final hundred or so insects.

Isaiah's POV:

"Hey, old man. What's up?" I asked as I dismissed my bow, with it breaking down into motes of blue light before it formed into a black glove with blue tribal markings on it.

"It's time we moved to the next territory." Okita said and I shrugged as I walked towards them, stretching my sore arm and finger muscles from shooting arrows on end. The arrows are created by taking a small bit of my energy and formed into my signature elements, so as someone with Peak High-Class Demonic Energy, I can shoot it for about seven or so hours, give or take an hour, before I need to rest to gain back the energy.

Thankfully, Bardou is here to release a blanket of flames as I get my energy back. Unfortunately, the arrows are powerful enough to kill Peak Middle-Class beings, but not strong enough to even pierce the skin of a Low Ultimate-Class being.

"Aw~ And it was so much fun to watch you destroy my children~" A raspy voice said in an amused tone, with me shivering slightly at the weird chill I felt from the voice before I turned to see Anubue flying towards us. The chimera was about double the size of Okita, with the wings and six legs of a fly, the body and mane of a lion and the tail and face of a wasp.

As it walked towards us, its tail slowly dragged across the ground and I tensed slightly as I stood just behind MacGregor and Bardou next to me. MacGregor didn't even waste any time as he created a crimson Gremory Crest under us before we disappeared in a flash of crimson just in time as his tail pierced the air where we were.

"And here I thought he was different." I muttered and Okita just chuckled.

"First thing you need to know about the familiars of the first Satans. They care for nothing but themselves and their masters." I just nodded before the two of them disappeared, leaving me alone once again in new and unknown lands.

"You would think that they would've at least let me know about whose territory I'm in." I muttered to Bardou, who just shrugged before we looked around and I gulped slightly. We were on an island. A barren and deserted island that had only fruit trees with even more islands around us, though most of them seemed to be deserted as well.

'I thought the Underworld didn't have seas.' I thought with a frown before my eyes widened as I jumped back from the sea, Bardou following me just in time for a humanoid shark to bite down on the area where we were. Without hesitation, a bright red dagger with golden streaks on it appeared in my hand before I threw it at the shark. The dagger pierced the throat of the shark before it gasped as the area around its neck blew up.

The shark's head rolled over the ground and into the water as its body flopped down on the sandy ground.

"So what now?" I asked Bardou, who just shrugged before he quickly turned around and let out a beam of compressed fire at a school of flying fish that tried to attack us from behind. The water under the flames turned into vapour and the fish were turned into nothing but ash that floated on the surface of the water.

"I guess this must be the territory of the familiar of the first Satan Leviathan. I don't think the Familiar of Lucifer would be found in water." I muttered out loud as I looked around right before I froze. Bardou was confused at me staring in horror behind him before he turned and froze silently right besides me.

In front of us, swimming in the water, was the head of a giant serpent, its bright yellow eyes with slitted pupils staring down at us as its sea-green scales glinted in the bright light of the sun. It grinned down at us, revealing rows upon rows of the pearly white greatswords it had for teeth before it spoke with its loud, deep and booming voice.

"Would you look at that? A little devil and the spawn of Agrukk hiding away in my territory? Oh, and I see you've killed one of my subjects. I should kill you for that." I just kept quiet as I stared at him with wide eyes, mostly because of the fact that the aura he exuded was much, much larger than that of Agrukk. The fact that his head was almost half the same size as the island we were on was also a worrying fact.

"U-Uh, hello. May I have the pleasure of knowing your name, great serpent?" I may be a prideful idiot, but I knew when to give respect to those that could destroy half an island with nothing but a bite, especially when that doesn't even take into account him using whatever abilities he has.

"Ah, that means that you were placed here without your knowledge. Well, allow me to inform you. I am Grithyx, Lord of the Serpents and King of the Drowning North. A pleasure." Unlike Agrukk and Anubue, he didn't roar his name or titles out for all to hear and yet, the soft way he introduced himself along with the fact that the water and sky calmed as soon as he spoke terrified me much more.

"A pleasure to meet you, Grithyx I'm Isaiah Azathoth, Knight of Rias Gremory and a High-Class Devil. With me is Bardou, son of Agrukk and my familiar." Bardou bowed his head slightly with a bark and Grithyx chuckled.

"Let me guess, you met Agrukk and Anubue first and based the behaviours of all of the Satan Familiars on what they do, didn't you?" I nodded with a shrug and he chuckled.

"I suppose those two imbeciles were the worst ones for you to meet first. Well, know that Comraicrer and I are not as…destructive and arrogant as those two. They're still stuck in the old era of when we fought against the God of the Bible, his Seraphim and the Grigori. Do not worry as I will let you stay in my territory and will let my subjects know that you are my honoured guest. However, do not misuse my generosity. This island is yours to train on and if the denizens of my territory attack you even after I told them to leave you alone, you are free to kill them. However, if you attacking them out of free will, I will come and kill you myself, understood?"

"Yes, Grithyx." I said with a nod and he nodded before he sunk back into the water, disappearing from view as soon as the last bit of his head disappeared under the water. As he disappeared, I sighed as I sat down onto the ground, Bardou flopping back on the ground next to me as I groaned.

"Just once. I just want to be left alone to train for just once." I muttered, Bardou whining next to me as I chuckled.

3rd Person POV:

With Okita and MacGregor:

"…Next time, let's just go somewhere where the kid won't be threatened by a God-Class being whenever we arrive." MacGregor said with a sigh and Okita just gave a sheepish chuckle.

"Yeah…Maybe we shouldn't go to Comraicrer's territory and just head to the Human Realm." "I wasn't the one who said that the kid had to learn how to survive before he learns anything new." Okita just grumbled at MacGregor's words before they saw Isaiah standing up from where he was lying on the ground, creating a pair of silver and dark grey falchions in his hand before going to shadow-fighting as Bardou fired a constant stream of violet flames across the water in order to train the intensity of his flames.

"I suppose it might be time soon to go to the next part of our training." Okita muttered and MacGregor nodded before they continued watching.

Two Months Later(Month 9, Year 1):

Isaiah's POV:

"Hey, gaki. It's time to go." I heard Okita say as he and MacGregor appeared in front of me and I nodded as I closed the tome I had on Gremorian before putting it away. It really was a fun runic language to learn if you ignore the fact that I've just barely learned about 5% of the language. It took me a year to learn all of the known runic languages fully and yet, it took me almost two years to learn just 5% of Gremorian.

I can see why it was so revered amongst the rest of the Supernatural World.

"Okay then, so are we heading to the final territory?" I asked curiously only to be confused by their negative headshakes.

"Nope. We're heading to a friend of mine in the Human World that will help you get a better understanding of Touki and your body." Okita said and I nodded before MacGregor placed his hands on our shoulders. Instead of the Gremory crest, a bright white crest with a tombstone that had 'XIV' written on it appeared under us, flashing brightly before our surroundings changed.

Instead of the barren island, we were now standing in front of a large and red Torii gate, a large set of stairs behind the gate and heading up to the top of a very tall mountain, with its peak hidden behind the clouds.

"Welcome to Mt. Everest, home of the person we're meeting." Okita said before I heard a new voice speak.

"Well, well, well. Looks like the idiot is finally here." I turned to see a short man walking towards us, his body covered in golden fur. He was wearing a monk's cassock, a wrinked, creased face and dark skin, wearing prayer beads around his neck and a golden headband around his forehead.

"Sun Wukong." I muttered in awe, drawing an amused look from the man in question as he nodded at me.

"Thank you, once again, Sun." Okita said only to yelp as Wukong whacked him across his leg with the staff in his hand, which I realized was Ruyi Jingu Bang, the famous staff of Sun Wukong.

"Now then, gaki. The one who's going to be training you is waiting at the top of the stairs. Start walking." Turning back to stare at MacGregor and Okita, they just shrugged as I sighed before starting with my long trek up the stairs, Bardou waddling along next to me before he was pulled back by Okita.

"Nope! He's going to do it on his own or don't you want to teleport up with us?" Bardou glanced at them before giving me a smirk and a shrug. I just grumbled as I kept walking up the stairs. Time to see who this teacher is.

Later That Day, Evening:

Mt. Everest:

Isaiah's POV:

"I'm going to murder the old man." I grumbled under my breath as I continued my trek up the staircase towards the peak of Mt. Everest. They didn't say that I couldn't use my speed or wings to get up the mountain, but the chance to use them disappeared as soon as I took my first step on the stairs I couldn't feel my Demonic Energy nor call my wings out nor activate Sword's Birth or Blade Blacksmith. That and the pressure pushing down on me as a result of the runes written on the stairs that exuded a devastating aura.

It's been close to a few hours that I've been climbing this thing and so far, I've only made it a quarter of the way up. That would be impressive in terms of human standards, but to Devil' standards, that was a bit on the slower side.

'Oh, looks like there's a new traveller trying to get to meet me.' All of a sudden, a voice spoke into my mind, startling me as I almost stumbled and nearly rolled back down the stairs.

'Ah, my apologies, I may have forgotten that most beings are not used to me speaking into their minds.'

'It's…okay.' I answered mentally as I looked around, trying to see who was talking to me.

'Oh, I'm not near you currently. I'm the guy who's waiting for you at the top of the mountain.' I just sighed before I looked back to the staircase, watching it stretch up high into the sky.

'So…can I know your name?' I asked only for the voice to chuckle amusedly.

'You'll know my name when you've finished your trek up the mountain. Now, let me know your name.' I wanted to say the same back to him, but that would just lead to him annoying him so I sighed.

'I'm Isaiah Azathoth.' I spoke only for the voice to chuckle.

'Yes, that is your name, but is that who you truly are, reincarnated Soul?' I froze instantly on the stairs, my mind running at lightspeed as the voice chuckled at my response.

And there goes any sense of peace that I felt.

'Do not worry for I shall not reveal what you are or rather I cannot. A being higher than the primordials visited me and told me that if I do, existence itself will be destroyed.' I frowned slightly in confusion at his words before a familiar face appeared in my mind that I haven't thought of for the past few years. It must've been the old man in the toga that I met before I became Isaiah, but who was he? And how powerful is he to make someone much stronger than Sun Wukong nervous?

'How did you figure it out?' I asked as I kept walking, now taking long strides as I rushed up the stairs as fast as I could.

'No 13 year old has this developed of a mental consciousness no matter how much of a prodigy/ genius they are. That or possession, but even then, there would have been signs of the possession, which I believe is something that MacGregor would have noticed and kill you already.' I just grumbled as I kept walking.

'So what now?' I asked only for the voice to hum.

'Well, I've never trained a reincarnated soul before, so I'm excited to see how fun this will be.' The voice said in an excited tone and I blinked owlishly, stopping in my tracks.

'You're…not upset about me taking over the body of a young boy or the fact that the world might be in danger because of me?' To my surprise, the voice chuckled boisterously.

'The world is always in danger of being destroyed, so you're nothing new and the boy who was previously the host soul of that body died, so you taking over the body in fact made sure that his legacy kept living on.'

'Okay, then I'll see you at the top.' I muttered and I could feel the smirk from the voice.

'And maybe we can figure out who you truly are, young soul.' For the first time since I began my climb, I chuckled as I nodded instinctively before I kept on walking. It was silent for the next hour before I heard the voice speak once again.

'Yeah, I ain't waiting a full day for you to get up here. Come on up.' And I heard fingers snap before I gave a manly yelp as I got pulled at blistering speeds towards the peak of the mountain, piercing right through what felt like a bubble of air before falling to the ground. Landing face first on the ground, I groaned as I pushed myself to my hands and knees.

"Ah, and now we meet face to face, young Isaiah." Looking up from my prone position, I saw a surprising sight.

It was a tall, muscular man in a black tank top, black baggy pants with dark blue semi-rimmed rectangular glasses along with robes tied around his waist wrapping back to his hands. He wore a bindi on his forehead and his light green hair, with black on the sides, tied backwards in a classical, old-fashioned way with what appeared to be a golden type of crown. In his mouth was a lollipop and his canines peeking out from under his upper lip. The most amazing thing about his looks were his eyes. Instead of normal circular pupils, he had lilies as replacement, each one shimmering with the colours of the rainbow as he stared down at me.

"The name's Gautama Siddhartha, but you can call me Buddha." The man, Buddha, said with an easygoing grin and I smirked as I climbed to my feet, though that didn't keep the look of awe out of my eyes as he chuckled.

"Come, that brat Okita dumped you in my lap and that means you're my responsibility for the next few months or at least, until you finished your training." I just sighed as I followed him, a large, golden Shichishito-styled sword floating after us as we walked towards a large golden palace in the far background.

Time to train under Buddha…oh, this is going to be fun.

A/N: Firstly, I actually had something planned for the Leviathan's territory, but I've been feeling…not tired or lethargic but…uninspired, I suppose is the best way to put it. It's like I write the stories, but they don't…they feel meh, average, not bad but not good either.

Also, I've been sick with this fucking stomach bug(I don't think it's a stomach bug, but the toilet and I have been very well acquainted for the past week, so I'm guessing it's a stomach bug), so that's also making me more tired. I'm not stopping the weekly uploads, but I'm going to try and upgrade the quality of the stories and that might take a while.

Anyways, leave your reviews as always and I'll see you all in the next chapter.

Until then…Ba-Bye~!

Edit Note: Yeah, I couldn't leave the chapter like that, so here's another bit that I wanted to add to make sure that the story broke at least 3K words.
