Getting back on the mountain was probably a bad idea...I am a demon slayer but a lower rank and a successful healer. Being born in a village is exciting, but many grieving moments happen when a person goes "missing" or just gets eaten by those disgusting mutated demons. I hated them. I hated them ever since my family was alive, but not until I met Tanjiro's sister, Nezuko. At first, I thought she would go crazy and eat humans as any demon would, but it turns out she's different than the rest, yet she's so adorable I just had to play with her! Later on, I made more new friends, Tanjiro, Zenitsu and Inosuke. Everything seemed normal, but out of the four friends I have......one of them I knew I'd never regretted calling a "friend."

Z: "Y/n~chaaaaan~!" Sighing, I already knew Zenitsu would aim for me; all three of us were going on a mission inside a mansion where at least three demons had stayed there, eating all the humans and not ever coming out. Z: "Y/n~chan, please stay and protect me!.... I don't wanna diiiieeeee", Y/n: "Zenitsu you're not going to die but you'll have to come with us anyway, it's our mission and we have to do it no matter what". He thought of me as some brave princess coming to save him, but he was only half right. T: "Come on Zenitsu lighten up we are almost there (no pun intended pls)" Tanjiro said as we kept walking to our destination while dragging the whiny Zenitsu from the ground. As we stopped, we saw two children in fright, holding each other very dearly, making me feel nervous throughout my whole body.

T: "Are you two ok?" They didn't say anything but just stared like they were soulless beings. Tanjiro tried to calm them down as possible as Zenitsu shaking in fear while staring at the building hearing things, I don't know why but that place is giving me bad vibes already. Y/n: "I hate to tell you this now, Tanjiro, and start acting like Zenitsu suddenly, but can't we just find a different mission until someone else comes? I can feel horrible tense feelings in there." Z: "d-do you guys hear s-something in there"-.......SPLAT! The children, including Zenitsu, screamed, causing me to jolt and turn around, seeing a bloody corpse that had hardly landed right behind me. Y/n: "HOLY SH-" T: "Y/n help him!!!" Tanjiro yelled at me as I kneeled and got close to the corpse, making my clothes drenched in his moist, disgusting blood......of course, I'm not used to blood when it comes to being a healer. Z: "I-is he d-dead?!" I hushed up Zenitsu, hearing what the man was saying while at least giving him treatment, but it was too late to heal him......yes.....he died. There was a long silence until I spoke up, Y/n: "I'm going in..." While slowly dropping the body and walking inside, Tanjiro agreed and followed right behind me, letting the kids stay behind with Nezuko. Z: "Wait, you guys are not serious, are you?!" He could hear me mumbling, saying I'll beat the hell out of his ass if he doesn't slay the demons already in pieces which caused him to follow nervously.

Z: "T-Tanjirooooo...... can't you fight it?". Tanjiro just shook his head, T: "I've broken some of my bones during my last mission, so I can't do much." Zenitsu's face changed immediately, frolicking on the ground, repeating over and over, Z: "I KNEW IT, WE ARE GONNA BE DEAD SOON!!!". I sighed heavily in frustration but looked over, seeing the two children running towards us, T: "H-hey, I thought you guys were supposed to stay outside?" ?: "W-we heard weird scratchy noises coming from inside the box and decided to come over." Only for a minute, the weird sounds came back but only louder, making Zenitsu scream and bend down, bumping Tanjiro and the girl to a different room, but suddenly they disappeared out of nowhere. "Did they just....... vanish?" I looked at Zenitsu, back into the hallway, and walked away. Z: "W-w-wait y/n, please don't leave us!" He was crying and whining, begging me to stay, though it was cute. Y/n: "I have an idea, but you won't like it......if we split up while the rooms are changing, then one of us has a better chance to get closer to the demons and kill it!" The younger boy thought it was the dangerous idea but slowly agreed. Z: "ARE YOU CRAZY?!!! YOU CAN'T JUST LEAVE US ALONE!!! WE NEED YOU TO PROTECT US PLEEEEASE!" Ok now I'm starting to regret calling him cute....it's so freaking irritating.... Y-n: "Fine, Zenitsu, we'll stay close, but we must change plans for now."
