My Upgrades Are Invincible

We spent a whole day just hopping between trains and me buying a horse drawn carriage for the last leg of our journey and finally we managed to reach a secular mountain surrounded by Wisteria trees which would act as deterrent to all but the strongest demons, basically any demon that want an upper moon after trying to push through all these Wisteria trees would quickly collapse from the poisons especially after hearing that the servants who basically lived there whole lives with the family who ran the Demon Slayer Corps built a strong immunity both by literally centuries of breeding to do and just sheer over exposure.

Those servants were able to grind up and paste the concentrated Wisteria everywhere off the road leading up to the mansion so anyone who wanted to reach the leader would be harassed for god knows how long as they went up the winding path.

Though that wouldn't really happen as should Muzan decide to finally assault this place he could just have Nakime open a portal here.

"Jake, I must ask you to be respectful to the master." Giyu spoke out as he sat beside me on the cart.

I sent a surprised look at him responding. "Hey, I am not the type of person who attacks others as a greeting or not even bothering to get any confirmation about my status as a human being." I lectured him making his face twitch in irritation at my rapid-fire insults.

"Be as it may, I am not speaking only for myself but to let you know that the master has a deformity upon his face from bearing the cursed bloodline of the first demon. Now what I meant by this is for your benefit is to not react or do anything disrespectful towards him as all the Hashira see him as a sort of father figure or otherwise beloved person." Giyu explained making me nod in understanding as although I could certainly escape the encirclement of all the Hashira, I certainly wouldn't be able to defeat them all unless I literally burn them to a crisp.

"Alright that's fine and all but I have a question?" I asked after a moment of silence as he let me digest his words.

"Yes?" He responded bluntly.

"If I can heal his deformity with my magic would the Hashira and he treat us more favorable in whatever negotiations?" I asked and then the whole world went quiet with even the horses pulling our cart shuddering as Giyu turned toward me as well as two figures dashed out of the surrounding trees.

"Stop!" Giyu yelled and the I recognized the Snake Hashira Obanai Iguro and the Wind Hashira Sanemi Shinazugawa and they looked mutinously towards Giyu as I knew they were both the more ruthless duo of the current generation of Hashira while also being heavily loyal to the lord of the Demon Slayers Kagaya Ubuyashiki.

I could hear the wood groaning in Sanemi's hilt as his hand gripped tightly and he growled at Giyu. "That bastard was speaking nonsense after us demon slayers have spent centuries trying to cure the Ubuyashiki blood line, he thinks he can just waltz in here and offer some snake oil magic nonsense after you were so weak to get your ass beat by a foreigner?" Oh, goodie my first time being called an outsider, heh if only they knew how truly out of the box, I am in terms of this world...

Sanemi then looked towards me and steadfastly ignored Obanai muttering about how snakes weren't oily in the slightest. "Why don't you step down here off that cart and let me show you how strong a real Hashira is!"

I sighed in annoyance as I just wanted to get the Kamado family some more permanent lodgings so I could try to beat the sun breathing style out of Tanjiro along with a couple others. "Look wind bag Hashira." I could hear both the water and snake Hashira snicker and my words and could literally see the veins popping on the scarred face of Sanemi, but I continued on ignoring how he was starting to walk toward me with his hand clearly about to draw his sword into a slash.

"I just want to get this family to safety, and I have a deal to make with the head of the Ubuyashiki household so either move aside or I will have to move you aside as we have been welcomed within by one of the family's speaking ravens." I was kinda jealous of those ravens and wanted my own talking raven that could easily remember long messages and be able to find people dozens of miles away.

The wind Hashira paused hearing how I was already invited into the home and knowing that should he attack me that would the very definition of a disloyal samurai attacking a person under guest rights. He snarled and I could hear his sword clink back as it slid an inch back into the scabbard and he removed his arm from his sword and folded his arms over his chest. "Fine but should you offer such a service, you do something to harm the master I will break you in every way I can imagine." With that ominous statement Sanemi took off at a sprint into the treelined and disappeared behind the lavender-colored Wisteria flowers.

"So Obanai any meaningless threats from you?" I asked and turned around where said snake Hashira had ninja sneaked atop the carriages roof and was obviously going to threaten me with the snakes hiding within his clothes.

The more levelheaded Hashira could tell with his position and how close he was to the Kamado family that should he say something as stupid as yes or actually threaten me, I would obviously launch an attack. His eyes someone was somehow able to show a decent bit of emotion with the rest of his face below his nose covered by a scarf, showing a placid smile as he responded in the negative. "Hmm no I don't think that will be necessary with how intelligent you seem. Well either way I shall see you up atop the mountain where the master and the rest of the Hashira are waiting for you, Jake."

I could hear his unspoken threat though of should he go for me it would be from my back and I only rolled my eyes as I didnt take a non-supernatural snake seriously as with my Pure Body skill literally only Muzan's blood would be able to take me out of a fight within this world as far as I was aware.

Obanai like his fellow Hashira dashed into the tree line obviously taking a shortcut through the Wisteria tree's leaving Giyu to escort us to the top.

"They are still watching us, aren't they?" I asked wryly.

Giyu snorted and rolled his eyes. "Yes, and if anything, they are going to be judging your every move even harsher so let's make haste before any of the other Hashira get bored and deicide to test you or something."

I acknowledged his words by giving the duo of horses pulling my cart a nudge and they picked up into a slow trot rather than the causal walking pace they were already at.
