20 - MT. NATAGUMO, I.

The four were nearing the mountain when suddenly, Y/N asked a question. "What breathing techniques do you guys use?" The three looked at him. "I use Thunder." Zenitsu said, looking away. "Woah!! I have a friend who uses Thunder, too! It's really cool!" The (h/c)ette said excitedly, giving the blonde a smile, which made the older boy blush. "I use Water." Tanjiro said, giving their new friend a small smile. "Like my aniki! That's also cool!" The latter grinned, which made the burgundy boy's smile extend too. "WELL IM COOLER, BECAUSE I USE BEAST BREATHING!" Inosuke suddenly yelled out, which peaked Y/N's interest. "Beast? I've never heard of that before.." The e/c male said cocking an eyebrow at his peer. "I made it myself!" The shirtless boy boasted, laughing in the process. "Wahhhh!!! How cool! And you have two swords, so you're a dual-weilder, right?!" Y/N's eyes were sparkling at this point, actually interested in the new breathing technique. "Yes, I am!" The masked boy said cockily, smiling under his boar hide. "I'd say like me, but I'm practically a quad-weilder, so you're like Tengen-san!" The (h/c)ette explained, thinking of his flamboyant friend who liked to pretend to be his father. "Quad? How?" Tanjiro asked with visible confusion. The other two were curious as well. "I have nichirin blades in my shoes! I created a breathing technique that allows me to utilize all of my limbs, heh. I call if Cloud Breathing." The pillar explained, leaving the other 3 stunned. "Is that why your uniform is white?" Tanjiro asked, as Zenitsu giggled at how pointless the question was. "Actually, yeah. I requested for it to be made like this instead of having the same uniform as my former sensei. I didn't want our clothes to get mixed up either, since we live together." Y/N confirmed, a smile being brought to his face when he thought of the Mist pillar. "You live together? Are you lovers..?" The oldest of the group asked bluntly, visibly upset and about to cry. "No, but.." The Hashira started, but refrained from continuing his sentence. He just smiled before speaking again. "Nevermind" That was the last conversation the 4 managed to have as they reached the base of the mountain.

"Ah, it looks like we're here!" Y/N sighed, seemingly in contention, as he put his hands on either side of his waist. The three were about to start climbing, until they saw a slayer crawling away from the mountain. "Save.. me.." The slayer said, but the moment the 4 tried to approach him, he got dragged back up into the trees while pleading to be saved. Zenitsu started crying immediately, saying that he doesn't want to go, while Tanjiro tried to comfort the older. Inosuke tried to convince Zenitsu that they had to go due to their mission, but he still disagreed, saying that he doesn't care if it's a mission and that he will die. The situation had Y/N sweat-dropping in the sidelines. "Look, Zenitsu, we really need to get up there. I was supposed to get here earlier as well, but you guys were sort of slow, so now there's people in danger up there. If you really can't go, I won't push, but me and the others are off." Y/N explained as he grabbed onto the other boys' hands and started climbing the mountain with them. The blonde stayed back eventually.

On the way up, Y/N eventually let go of his new friends and put both of his hands on the hilts of his swords, just in case he had to fend off any demons. Inosuke seemed to get it and did the same, while Tanjiro looked around. They eventually met a guy who happened to be safe and approached him. Tanjiro went first to try and ask what happened. "W-who are you..?" The older male asked, looking at Tanjiro with a petrified expression. "I'm Kamado Tanjiro, ranked Mizunoto." The burgundy boy asked, crouching down to the level of the fellow slayer. "..Mizunoto?" The male repeated, his voice a whisper. His expression quickly changed as he became more nervous and angry. "Mizunoto? Why didn't they send a Hashira?" The man whisper-yelled, which took Tanjiro aback. Y/N chuckled, but quickly threw his hand over his mouth. The unfamiliar male gave him a confused glare before continuing. "No matter how many Mizunoto they send, it won't help! It's pointless!" The ravenette said, a bit louder this time. He was right, but then Inosuke punched him in the face. "So Annoying!". Tanjiro and Y/N were left speechless from the action. "Inosuke!" Tanjiro yelled, placing a hand between the males. "Shut up!" The shirtless male yelled in anger. He proceeded to grab the man by the hair, while Tanjiro tried to hold him off. "As far as pointless goes, your existence itself has no point at all!" He the masked male yelled at the slayer. This made the (h/c)ette burst out laughing. "Now, tell us what's going on, you spineless fool!" Inosuke said, bringing his masked face closer to the poor guy who was sweating bullets from the tension. "W-who the hell is this guy?" The man asked, his voice cracking. "A-after receiving our commands..!! From the crow.. 10 members got here.. However, after entering into the woods.. The other demon hunters... They started to.. Kill eachother..!" The male explained, looking as if he were about to cry. The 2 Mizunoto looked shocked, while Y/N was unfazed. After hearing the explanation from the slayer, they heard footsteps. Looking into the distance, they saw another slayer, who assumed an attacking stance and started going after them, along with another slayer who appeared moments later. Y/N leapt into the trees, watching the scene unfold. Inosuke was laughing like a madman while twisting and bending his body in order to dodge the attacks, ready to tear the corpses to shreds. The burgundy boy stopped him, scolding gum, but only recieved a headbutt in the stomach for 'spoiling the fun', according to Inosuke.
