Yandere Tanjiro and Nezuko Kamado (platonic)

-After everything they've lost, it's no surprise that Tanjiro and Nezuko would hold on to whatever or whoever reminded them of their family and their old life, everything that had been taken away from them. That's probably why they cling so desperately to you. There's just something about you, whether your appearance, your personality, or even your smell, that reminds them so much of home. You're familiar to them and that's all they need to start their obsession.

-Nezuko is extremely clingy. She clutches on to you any time she can, even taking to following you anywhere and everywhere you go. She loves being close to you, as close as she can possible get. Nezuko will even scratch and whine for you to carry her on your back when you're on missions, resulting in Tanjiro and you often taking turns doing so. Nezuko never wants to be apart from you ever. She's going to keep you safe and protected alongside Tanjiro.

-Tanjiro is overwhelming and downright suffocating, they both are really. He's also very delusional with no sense of self-awareness, far too deep in his delusions to even fathom what he's doing may be wrong and or even harmful. You're family and and that's all he sees, a lot like tunnel vision.

-Both Tanjiro and Nezuko are extremely protective. You are their utmost priority, even coming before finding a cure for Nezuko and all other demons. They've lost so much and in such a short amount of time, but they aren't going to lose you too. They aren't going to let anything happen to you. They can promise you that.

-It doesn't matter whether you're human or a demon, they're going to take care of you and love you. To keep you safe, but most importantly to keep you right by their sides, like a family.

-If you are a demon then it will only fuel Tanjiro's goal to find a cure for both you and Nezuko. If you're similar to Nezuko and haven't completely lost your humanity, then Tanjiro will make you your own box or something similar to protect you from the sunlight. They both would want you with them 24/7.

-If you aren't similar to Nezuko and are more aggressive and have overall given into the demon side of you, then Tanjiro will keep you somewhere else. Somewhere safe, a place only he and Nezuko know. He'll take whatever precautions to not only keep you safe but keep people safe from you. He'll make sure you're fed and taken care of, but not too strong that you'll be able to get out of wherever he's keeping you. He loves you, cares for you, and he's not going to let anyone take you away from him and his sister. Even if you hate them, hate him, he's not letting you go.

-Now if you're a fellow Demon Slayer then you're going to see Tanjiro and Nezuko everywhere. Somehow all of you end up in the same place. You chalk it up to coincidence or whatever else, not honestly believing these two would be tracking you or following you by any means. Little do you know that's exactly what their doing. Tanjiro will try to persuade you into joining them whenever you do run into each other. He can be pretty persistent too. Not really taking no for an answer. If you don't join them then they'll just join you.

-Tanjiro hates punishments, he really does, but if he has to then he'll punish you. He's not sadistic, he doesn't like seeing you hurt whatsoever, he's doing it for your own good. You need to see him and Nezuko how they see you; as family. That's what you are now. What you'll always be to them. Family.

-Nezuko is always there to comfort you after any form of punishment. She'll snuggle up close to you and pet your head like how you'd usually do for her. She'll make sure you don't hate Tanjiro afterwards, after all he's just trying to help you see what's right in front of you.

-Speaking of which, Nezuko really loves whatever attention and affection you give her. Having you run your fingers through her hair and laying on your lap is her favorite. She loves anything that has to do with being close, especially close to you. Whenever you are upset or sad Nezuko will try to comfort or calm you the same way you do for her. She'll often pull you into a tight embrace and just hold you. She can hold you for hours on end, just staying with you like that whether she needed a reason to or not. Her hold can get a little too tight more times then not, bone crushingly so. Sometimes she just forgets how strong she is now.

-Tanjiro is perfectly content just watching the two of you get along and close together, but that doesn't mean he doesn't give his fair share of affection. Tanjiro is full of just as much as love and affection as Nezuko is, maybe even more so if that's possible. He and Nezuko will often have snuggle piles with you stuck in the middle.

-As annoying and suffocating as they both can be, you can't say they don't melt you're heart. They just want to take back something they've lost and you just so happen to remind them of that. No matter what you won't be able to get away from these two, but will you really want to in the end? Could you really bring yourself to runaway from these siblings? Especially after all the love they've unconditionally drowned you in?
