Journey: Reunion (KNY/demon slayer AU)

Chapter 4: Those are spuder people!(Please don't call them spuders)

Muzan visiting at Mt. Natagumo

While Journey was helping out Tamayo and Yushiro, that same night, Muzan visited Rui within Mt. Natagumo. His aura has terrified the spider demons within the area, Rui, however is not. For he is part of the twelve Kizuki, lower moon 5. He respects Muzan highly and sees him as a father figure as well. Usually, Muzan visits Rui for reports, this time however, it's different.

Muzan: "It's so nice to see one of my lower ranks become so much stronger, lately, some have been slacking off."

Rui: " Thank you, Muzan-sama, I will tell you of what's been happening lately as my family has gotten a great amount of demon slayers."

Muzan: "I appreciate your hard work, you can report me for next time, there is something I must speak with you urgently."

Rui listened carefully to Muzan's words. Muzan picked up Rui like he was a small child of his own, gently carrying him.

Muzan: "This is something I can tell you since you have a family of your own. Someone very close to me has returned and yet I'm worried for his well-being, my dear little Otouto has been reincarnated. Unfortunately, it seems that he is accompanied by a demon slayer, I know for certain he isn't aware of the demon corps itself."

Rui: "I understand, you want me to bring him back to you and get rid of the demon slayer accompanying him permanently."

Muzan ruffles Rui's hair playfully, smiling at the fact how he understood perfectly.

Muzan: "This is why I could trust you with this task the most, I would have asked for a certain higher rank, but no one understands what a family is better than you."

Rui: "I will make sure you two reunite once more."

Muzan: "Before I take my leave, I will describe what he looks like. He wears foreign clothes of blue and orange colors, yellow hair, blue eyes, and an odd sword."

The king of demons took his leave as he was satisfied with Rui. Lower moon five was surprised Muzan actually had someone close to him before. No matter, if one of his family members was missing or hadn't returned, Rui would actually try to find them instead of replacing them…

"If Muzan has a little brother… That would make him my big brother then…" Rui thought.

-Meanwhile-

Journey secretly returns to the wisteria house and into the room where the trio slept without any problem. He made sure to cover Tanjiro's nose and Zenitsu's ears before leaving previously due to their very high senses. It looks like time between here and his world was different. Since he did took a nap before returning here and now… it looks like it's going to be catching even more Z's.

Then morning follows as Tanjiro was the first to wake up, Inosuke second, Zenitsu and Journey kept sleeping although Journey woke up a bit afterwards. They were still in recovery from what happened yesterday and it seems like it's gonna be awhile… Of course, the doctor is gonna check them daily and he was surprised about the foreigner's condition.

Doctor: "Would you look at that, you are in great shape that quickly! Either the gods have blessed you or you really have good health boy!"

Journey: "Heh, I have been laying off the buffet lately, running and pumping my muscles also helped."

Doctor: "Well these three still have ways to go before being fully recovered, so just in case, you shall be taking a rest."
