Demon Slayer One Shots!!!

💢 Zenitsu | Empty 💢

Zenitsu had always had a flirty personality, and after 2 years of dating Zen and many more knowing him, you had gotten used to it. On a mission, flirting with girls. At headquarters, flirting. Nezuko, flirting. But he didnt mean it. Well, you thought he didnt.

It was around 3 in the morning when you had returned to headquarters, badly beaten up. You had your first mission without Zen and it was terrible being away from him for almost a week. As you walk through the estates gate you dont spot Zen anywhere waiting for you as you thought he would've been. Your shoulders slump slightly as you brush it off, thinking hes just asleep as you make your way towards the infirmary.

You check in, letting the medics look over your injuries as they take you to a bed mat. You lay down as they run some tests and check your cuts. 2 broken ribs, a broken wrist, and some deep lacerations on your back. They patch you up and ask if you would like then to go get Zenitsu for you. You shake your head, not wanting to disturb him from his probably well needed sleep. You slowly feel sleep taking over your body as well, exhausted from the successful mission.

You groan as you wake up, the sunlight hitting your eyes. The injuries you sustained felt much better as you stand up, determined to go find Zen now. You ignore the protests of the medics as you make your way to yours and Zenitsu's room, wanting nothing more than to just cuddle with him. As you slide your door to your room open your heart breaks, hurting more than any physical injury could.

You feel tears stream down your face as you see Zen cuddling with one of the lower ranked female slayers in the corps. You reach up and tug at the fabric above your heart, desperate to end the stabbing pain that racks your body as you sob. You slowly step into the room as you see Zenitsu rub his eyes.

"Z-zen?" You ask, your voice cracking as you wipe tears away, not making any progress as they just keep falling. Zenitsu raises up and looks between you and the girl, a shocked and pained expression on his face.

"(Y/n) chan?" He asks as worry takes over his body and he stand up, fumbling to grab his haori since hes only got shorts on. More tears prick your eyes as you see the girl in just her bra from what you can tell. You look away and tug at the fabric again.

"You c-cheated?" You ask softly, your sobbing making you choke over the words you never thought you'd say. The broken wrist you'd probably just injured again by tugging at your clothes didnt hold a flame to the pain in your heart.

"(Y/n) chan! Its not what it looks like i- I dont even know how she got here, I'm so sorry." Zenitsu says, stepping towards you, arms open for an embrace, tears glossing over his eyes. You step back, not wanting to be touched by your Zens hands who just touched another girl.

"D-dont touch m-me Zenitsu." You say harshly as you back into the wall in the hallway. A few tears fall from his eyes as he watches you runaway from him, down the hall and out into the courtyard.

You make your way over to Tanjiro's room, knocking lightly on the door. You hear shuffling and a muffled grunt, probably from Nezuko. The door slides open a bit, Tanjiro seeing it's you and he opens it completely, a worried look on his face as he sees you're crying.

"(Y/n) chan? What's wrong?" He asks as you just pull him into a tight hug, sobs shaking your body as Tanjiro picks you up and carries you into his room, Nezuko shutting the door behind him. He sits down on his mat as he holds you and you cry into his chest, gasping for air every few minutes.

You manage to explain what happened to Tanjiro, when you were calmed down enough to get a full sentence out. He listens quietly as you explain, every sentence making him feel worse and worse. Unbeknownst to you, Tanjiro fell in love with you the first day he met you, but of course you were Zenitsu's so he never said anything. The thought of Zenitsu hurting you replayed over and over in Tanjiros head as you finished your story and went back to sobbing into his chest.

He slowly strokes your hair as you eventually cry yourself to sleep. Tanjiro sighs before kissing your forehead and laying you on his mat, covering you with his haori as he gets up, looking at Nezuko.

"Watch over her for a bit, I'm going to go have a talk with Zenitsu, and get her some food and water for when she wakes up." He says as Nezuko nods and Tanjiro walks out, towards Zenitsu's room.

6 years pass since the heartbreaking day you experienced. The pain was gone, replaced with a dull loneliness. That was up until Tanjiro confessed he was in love with you 4 years ago. You were both 21 now, Tanjiro having proposed to you 7 months ago. And that brings us to now, your wedding afterparty.

"Oh (y/n) Kamado." You hear from behind you as you turn around. You smile as you lock eyes with your new husband, him pulling you in for a soft kiss that you gladly return. The entire corps was invited to the wedding, a big celebration that all surrounding cities heard of and would celebrate in their own ways within the town. After all, a demon and a demon slayer were now married, signifying a big turning point in history, the beginning of a peace among demons and humans.

One person however sat in the back corner of the banquet hall, surrounded by happy couples, dancing and celebrating the newly weds. He didnt feel like celebrating as he drank glass after glass of wine, hoping to numb the pain he was feeling. He should be happy. Happy that you're happy. Happy that he was married to the woman he had cheated on you with all those years ago. But he wasnt.

He watched as his pregnant wife talked amongst the other Hashiras. Most would tell him hes a lucky man, a loving wife who bears his child, but he wasnt lucky. He had lost the one person he loved and he couldnt fix that so he had to let you go, let you be happy and have what he couldnt. Oh no he definitely wasnt lucky.

He was just empty.
