Demon Slayer: Kimetsu no Yaiba (Complete)

Hearing the pitter-patter of feet come rushing towards me, Yushiro calls out to me hesitantly from the shade of a building.

"Shiro… you might want to see this."

With dead eyes, I look up and find Yushiro holding a letter of sorts.

"Way back when, you had asked us to examine your blood." I nod my head. "These are the results. They're the last thing that Tamayo had left with me. She only just managed to finish before… sacrificing herself." Yushiro chokes.

"And why should I care?"

Yushiro licks his lips, "I only read over them once, but there was one point in it that might be useful to you."

Snatching the envelope from his hands, Kanao trots over to me. Ripping it open, I scan over the paper, looking for anything that could be useful, anything that might save Mitsuri. After searching, the last line of the last paper let me lull my head backwards.

There, it read, "After extensive research, I have come to the conclusion that Shiro's blood, much like Muzan's, can transform others into demons. And with Shiro's innate immunity to the sun even as a demon, that trait will be passed on, just like the powerful regeneration, immortality, an accelerated growth rate, enhanced physical prowess, and even Blood Demon Arts."

"What does it say?!" Both Shinobu and Iguro ask urgently, wanting to know how I was able to calm down in a situation like this.

"Mitsuri will be fine."

"And what does that-"

Cracking my eyes open to know the reason for their silence, I follow their eyes to the place where Mitsuri was stabbed and see that it had disappeared. Within the next moment, Mitsuri cracked her eyes open, but instead of revealing her normal pale green eyes, they took on a color closer to that of her hair. Starting with a light pink that fades into a lime green color.

Beside that minor change in appearance, plus the elongation of her nails that were pink everywhere except her pinky fingers which were also lime green, nothing else had changed. Watching as she touches at the spot where Muzan had struck, her eyes glitter brightly.

"Shiro-san, I didn't die, right?" Her attitude then turned flat, "Or is this the afterlife? Shiro-san, that's not good if that's true, what will Shinobu, Kanao, and Nezuko-chan do without you. Even if you love me, you shouldn't have left those three behind."

Her eyes then find both Obanai and Shinobu. "Ehh… you guys followed me too, but there was no reason to."

Mitsuri looks like she's ready to cry, but all three of us shout, "You're not dead!"

"Oooh, I see. That's nice…" Mitsuri nods her head, before her look becomes complicated and she asks, "But how?"

Petting her hair as her head still lay in my lap, I answer, "Sorry if it was against your consent, but I fed you a bit of my demon blood, which allowed you too as well."

"That… doesn't really make much sense, but I'm alive, so I'll take it." Mitsuri giggles, "Also, I can't recall how your blood tastes, so mind feeding me just a bit more, I wanna know!"

"Mabey later… after all, we have a celebration to commence. We killed Muzan."

"It was more like you did…" Mitsuri pouts. "Even so, you're what pushed me that extra mile, so thank you."

I kiss her forehead, causing her to look coy.

Mitsuri then begins to touch her pointer fingers together, "So, you know that thing I said before I almost died, can we actually get married. Or not… you can also just ignore it." Mitsuri eventually got so soft that it was like a mosquito whisper.

"Mabey in the future, we'll have to see where it takes us after all." I shoot a gaze at Shinobu and find that she was giving a nod of approval.

Mitsuri shows the largest smile that I've ever seen her show before and she shouts, "So, in other words, that's a YES! Let's get married soon okay. Though, I will follow the common marriage rules and allow Kanao and Shinobu to get married before me."

"I'm only sixteen." I deadpan.

"And?" Mitsuri cocks her head, "I've seen people getting married at fourteen, and you're well pass that mark."

Mitsuri then goes silent for a moment and asks, "Are we really sure that it's over."

Nodding my head, tears pop up in Mitsuri's eyes and they begin to flow. Continuing to pet Mitsuri's head, my chin is then grabbed, and my head upturned, smacked incredibly hard, and then I'm given a searing kiss on the lips.

Going back to her sitting position with her face burning red, Shinobu squeaks at me, "What you did was extremely reckless and as your… girlfriend… it was incredibly harrowing for me. Please, never do something like that again… I love you after all."

Having my head grabbed by someone else, I'm given the same treatment by Kanao, minus the painful slap. "Shiro… I love you too… so please stay safe."

"Umu, I want that too." Having my head yanked downwards, Mitsuri gives me a light peck on the lips, but it instantly sends her to partially hide her face behind her Hashira Uniform's sleeves.

It was finally over.

~Three Months Later~

"The cherry blossoms are in full bloom."

"Yeah." A tired Kanao lets out.

"They're so beautiful." Nezuko states.

Disappearing inside of the Ubuyashiki estate while leaving them behind, I enter to find every single Hashira in attendance.

"Thank you for coming. Today marks the Final Pillar Meeting. Shiro. Sanemi. Giyu. Mitsuri. Obanai. Gyomei. Muichiro. Kyojuro. Tengen. You're the final pillars that will ever exist. Most of the other children have left us. But we managed to exterminate the demons. Thus, the Demon Slayers are disbanded as of today."

"""As you wish.""" All of us respond.

"You risked your lives for the longest time. You fought and devoted yourselves for the people of the world. We, the Ubuyashiki family, thank you from the bottom of our hearts." Kiriya bows.

"Please raise your heads!!"

"We don't need any of your gratitude!"

"The biggest reason why the Demon Slayers stayed together is because of the efforts of the Ubuyashiki Family!"

"Kiriya-sama you did a magnificent job as well. So, I believe that all of your ancestors in the Ubuyashiki Family, including your father, would be very proud."

Kiriya breaks down and cries, "Than you so much…"

Completing the very final meeting that we'd ever have, we all step outside and let out another cry for our victory.

"Shiro!!" I'm brought into a crushing hug by Gyomei. "It was all thanks to you that we can finally rest."

"Thank you, Shiro-san, for relieving us of our service! If you are ever in need of anything at all, you can come to me!" Rengoku shouts.

Laughing and chattering with the Hashiras, we all invite each other's families or close relatives for a final Demon Slayer party. Though, it was more of a party for the entirety of the Demon Slayer Corps. The Swordsmith Brigade and the Kakushi, the party was completely full, and the laughter boisterous.

Even though the Demon Slayers were disbanded, many didn't have homes to return to in the first place, so they continued to live in their residences of the Demon Slayer Corps if they had one. And even though the Kamado family had a home to go back to, they stayed with us in the Butterfly Mansion. Urokodaki moved from his place in the mountains and joined us as well.

For a last memento to all those who had given their lives, the pillars took it upon themselves to deliver flowers to all the grave sites. It was a long and arduous process, but it was the right thing to do.

There was no more overarching threat, no more missions to go on, and so I rest, living life the way that I wished to.

~Approximately Two Years Later~

It appears the moment I turned eighteen years of age, that my marriages were set into motion. Not only was it with Kanao, but also with Shinobu, Mitsuri, and Nezuko. And instead of us drinking from a single glass of wine, we instead drank a single glass of my demon blood.

They all thought that my blood tasted like the greatest drink ever, but I thought it tasted like iron. And I had to do those four times, even though Mitsuri was already a demon.

Her excuse was, "If they're doing it, then I'm doing it too." And who am I to reject my lovely wife.

They all had subtle appearance changes, but all in all, I thought that it made them look more beautiful than before. Though, I must say that making all of them demons was a slight mistake since when it came to them having Unlimited Stamina & Endurance, I think you can guess how our time in the bedroom went.

And now, I sat on the Butterfly Mansion's porch, brushing Nezuko's hair when a rather memorable blue box shows up in front of me.

[Congratulations on completing the world of Demon Slayer: Kimetsu no Yaiba. Due to the will of the higher being, you will be transported to your next world, when you are ready.]

Leaning down, I whisper into Nezuko's ear, "Are you willing to travel to other worlds with me?"

"Of course." Nezuko doesn't hesitate to answer, even though I knew she didn't know what I was implying.

Standing up, I hoist Nezuko up and walk hand and hand with her inside. Calling an emergency meeting for my wives, we all sit at the Chabudai.

"I plan on leaving this world soon…"

I don't even get to finish my thought before Shinobu slams the table. "What do you mean you're gonna leave… Are you going to die?"

It appears the memories of when we fought with Muzan still haunted Shinobu to this day, but I shake my head.

"I have no plans of dying anytime soon, what I mean, is that I have the ability to traverse to worlds besides this one."

"Like the one's above us?" Kanao asks.

Shaking my head again, I explain, "It's more like I can travel to worlds opposite one. One's with different pasts, presents, and futures than the one was standing in. For example, in a different world, there existed no demons."

"But why would we need to go to a safe world when we rid this one of threats?" Nezuko inputs.

"Because I don't really have a choice… For reasons I don't know if I can explain, I will eventually be forced to traverse to another world. So, the reason I've called this meeting is to ask this," I swallow hard, "Will all of you be willing to travel with me? These worlds can be horribly more dangerous than the one we live in right now."

Mitsuri smiles, "We're your wives, right? So, we're willing to follow you to hell and back if it means that we can stay with you. Of course, I'll go with you"

"Will we ever have a chance to return?" Nezuko asks.

"P-probably… not." I tell the truth.

"You should go with him." Kie walks in and comforts her daughter. "In all my years that I've raised you, I've never seen you happier than to be with Shiro. You might be leaving behind your family here, but you can simply build your own, with the person that you love."

Shedding tears, Nezuko buries her head in Kie's embrace. "Thank you."

Wiping away her tears, Nezuko resolutely states, "I'll go with you as well."

Looking to my final two wives, Shinobu waves her hands nonchalantly. "Is it even a question, of course I'll go with you."

Kanao nods her head, "I'll go."

"Thank you." I gently smile, "I love you all."

Proceeding that conversation, we held a Butterfly Mansion meeting to explain that we'd be going on a very, very long trip in which we might never return from. It involved a lot of crying, a lot of farewell gifts, and a lot of travelling to see all those who we would be saying goodbye to, but we all were ready to go.

[GOD has seen that you are prepared to leave, so say farewell.]

Turing around, I look at the crowd that had come to see us off and I start crying, waving to them as I walked away.

All of us were still sniffling even when our crowd was out of sight.

"So… how does this… work?" Mitsuri wipes her still falling tears.

Instead of me being the one to answer her question, a black void appears in front of us.

"Is it safe…?" Shinobu shivers.

"We'll never know until we try."

Stepping through alongside my wives, the blue box appears again.

[{Shiro} plus {4 others} are ready to travel to another world, GOD is now spinning the wheel]

Feeling a sense of doom wash over me to know that the wheel was the main source that chose our world, I let out a silent scream of agony. Seeing the multi-colored wheel appear in front of me, it begins to spin violently, not letting me see a single option that it held, though as it began to slow, and it finally looked like it was going to stop, there were three worlds that it could land on, and I had to hope that it landed on the one I wanted the most.
