My Upgrades Are Invincible

As me and Rengoku relaxed in another room I decided to see if Rengoku truly was a walking meme, so I shared some of the Pizza I had stored away in my time locked ring, so it was just as fresh as when I put it in.

"Delicious!" Granted it want the Umai or whatever he was made of a meme of, but all translators are a bit fault and I doubted even a divine translator isn't without faults like the one my falna gave.

But sadly, I realized an annoying character trait of Rengoku... He would loudly say his food was fucking delicious every other bite and it wasn't that he was yelling but all Hashira due to their strengthened lungs were loudspeakers.

'Let's see if you can say some ghost peppers are fucking Umai you flame headed glutton...' I thought hatefully as the man ate three whole pizzas in the time it took Zenitsu to scream like a girl almost certainly due to meeting Kanae as a real ghost would obviously make that pansy scream like a little girl.

Even as we walked out I was doing to some mental jumping jacks and I realized a number of the Hashira's would fit very well within my Familia with the exceptions of Sanemi and Obanai, the wind and snake Hashira respectfully as they were both loners but the rest would fit in very well as the Love Hashira would very much get along with Freya and Haruhime, whereas Shinobu and her acidic tone would certainly get along with Lili like a house on fire.

As for the rest I could easily see Giyu, Gyomei and the others basically adopting Bell as a little brother with how pure and naive he still is.

Either way my prior suspicions were proven correct as Zenitsu had launched himself into a tree and was screaming about a ghost and how we needed to bring a priest to exorcise her or something.

"Jake can my sister actually be exorcised or something?" Shinobu asked me obviously terrified of the thought of some priest waltzing over here and shaking some salt onto the spirit of her passed sister and watching her melt or something...

Seeing Shinobu's eyes tighten with murderous intentions I felt bad for any priest's or monks that pass by as she looked to be willing to honestly deal with anything that could approach her sister in a very permanent manner.

I had to think for a second before I responded. "Well, I pumped her full of mana so it's less of religious icons affecting her and more of her harming the mana I have filled her with that is making her body tangible rather than an intangible ghost she would have been originally."

Kanae hummed in thought, drawing all our attention to the beautiful dead lady... "Oh sorry it's just. I felt you filling me up so roughly when Shinobu went to hug me, so now that I think about it, I do feel different compared to when you originally summoned me which is probably your essence filling me and keeping me from feeling the draw of the underworld."

Ok... Ignoring how the big sister is teasing Shinobu and its interesting knowing where Shinobu's mischievous moments, it turns out the additional mana I provide keeps the draw of whatever afterlife is around from luring the spirits back.

"So Shinobu... My dear little sister... What did you barter away for me to be returned from the living?" Kanae said to Shinobu, and the room underwent a chill as Shinobu could only mutter something intelligible. "So, you agreed to marry him and make me an aunt finally! OK I approve!" Kanae said joyfully completely throwing Shinobu off her footing and even Rengoku was laughing heartily at the normally the tease Shinobu being bullied by her older sister.

"Rengoku what's your mother's full name. I will summon her and let you both get some time together while I go learn the Sun Breathing Method from Tanjiro." I asked and I could feel Kanae eyeing me, but I couldn't tell what she has thinking.

"Ah my mother's name is Ruka Rengoku... Can you leave some pizza as I got my appetite from her, and our fondest memories were going to restaurant's together before she became sickly?" He asked sheepishly and I could only snap my fingers and my last four pizza box's were left on a nearby table.

"God.. You and Mitsuri Kanroji are certainly going to triple my Families food expenses." I said sighing but I still held the resurrection stone with my hands and called upon Kyojuro Rengoku's mother.

Seeing the pale lady forming with black hair and almost pink eyes I clapped my hands as I stood up and filled up the woman with more mana as Rengoku took the surprised woman hands into his own in happiness.

"Alright you two catch up while I head out." I said walking out of the room following the way the Kocho siblings went previously when Kanae's teasing got too intense for Shinobu, and she fled before the older sibling could tell any sordid stories about her childhood.

After finding Tanjiro and wrangled him to teach me the correct way to breath in the Sun breathing method and then, I watched him go through the Sun breathing attacking methods, but it was plain that despite whatever reincarnation nonsense was involved in teaching him the methods and attacks from Yoriichi's point of view, Tanjiro simply didnt have the muscle memory for the sun breathing's supernaturally strong and fluid attacks.

But then a thought fucking struck me mentally like a train hitting a gong... I can just fucking call the soul of Yoriichi and have him explain it. Hell, I could just fill him up with mana and let him take care of Muzan for shits and giggles.

Like seriously just imagine the sheer pants shitting fear Muzan will have on his face with a resurrected Yoriichi running at him with a magical weapon.

Not to mention with how Tamayo basically knowing where Muzan is, I can wrap up this world with a nice bow with just couple of tricks.

Like spreading news about a certain blue flower that blooms once everyone hundred years is at a certain place... That insane battle that will decide this world will certainly be great, in other worlds it will secure my level up to Level five for my Falna.

I started laughing almost manically at the thought of pushing myself in deadly combat to fight all the Upper Moons as Muzan wouldn't dare to mess around as he has hunted down those blue flowers for a fucking millennium at this point... He will take the bait especially with how intelligent he is. He knows technology is growing more and more powerful.

Even as Tanjiro and Nezuko asked me what made so excited I just answered patting there heads. "Oh I just thought of a solution to dealing with Muzan..."

I didnt bother explaining and instead I gave Nezuko and Tanjiro some more tips on fighting while asking how Kie and the rest of there siblings were and they told me how Kie was basically acting as a secretary and taking down information to deliver to and from the Demon Slayer Corps's messenger birds.
