Half-Demon! Tanjiro AU Masterpost
(This has been my comfort AU for a while)
I personally love the idea of Tanjiro having some properties of a demon, but he can still keep his humanity. So here are some details about the AU! (Keep in mind that I haven’t finished the manga)
In this AU, Tanjiro couldn’t fully cure his demon side even after defeating Muzan, but he was able to regain his humanity. His body changed quite a bit and some of the changes are:
He doesn’t need to eat people and he could use his blood to make other demons regain their humanity.
He can bring back dead demons by rebuilding them using their Blood Demon Art remnants
He can also turn people (both dead and alive) into half demons
However, he cannot bring back a human if their head was destroyed
And he can’t bring back demons that don’t have a Blood Demon Art
He can control water to fight off hostile demons and to defend himself. Tanjiro can also use it to heal people.
When he’s pissed, Tanjiro can turn water into fire and use it as a heatwave (he’s only done this once though)
Tanjiro grew quite a bit. Now he’s 6 feet and 4 inches tall
When he is ready for battle, his fangs and claws come out and his eyes become those of a demon.
When he isn’t fighting, he just looks like a normal human with tiny micro fangs.
When it comes to sunlight, he can go out in the daytime, but his skin is extremely sensitive. He can’t stay out for too long, otherwise he gets an extreme sunburn.
After every battle, he needs to regain his strength by sleeping.
Tanjiro can also purr! He usually does it when he’s happy, sick, or injured.
He will occasionally hold someone who is sick or injured close and purr so that they can heal faster
The power of the blood demon art gets halved when they become half demons. This has angered quite a few demons when Tanjiro tried to convert them
Tanjiro still prefers to use his sword in battle. He only uses his fangs and claws if he has to.
He’s quite cuddly and his bigger stature makes him a giant teddy bear
Demons can communicate using a language of growls (it’s really cute!) and now Tanjiro can do that too
They can also communicate telepathically with Tanjiro like Muzan was able to do
When demons suffer from panic attacks or get too flustered, they lose control of their voice and they start growling, roaring and crying
Half demons also have human disguises, so they can walk through villages with no suspicions
He is the new Demon King! It take him a minute to get the hang of it, but he figures it out!
Tanjiro also is incredibly proud of the demons who’ve made progress
Everything here applies to Nezuko too, except the height change, water powers, ability to bring back demons, and the role as Demon King
In this AU, Tanjiro and Zenitsu are dating while Inosuke and Nezuko are just vibing and doing their own thing.

Tanzen Headcanons For My Half-Demon! Tanjiro AU!
(In this AU, Tanjiro and Zenitsu start dating and I want to elaborate on their relationship!)
First, let’s start with how they realized they had feelings for each other!
When Tanjiro went missing (to overcome Muzan’s control), Zenitsu couldn’t handle the grief he felt
He felt like he lost his source of stability and love
After all, Tanjiro was the first person to truly see the value in him
Nezuko tried her best to stick by his side and comfort him during that time, but it just couldn’t fill the hole in his heart
It was basically one of those situations where the character realizes that they are in love, but their special person is gone
When they finally found Tanjiro in his Half-Demon state, the trio was overwhelmed with joy
Tanjiro then picked them all up and swung them around in pure happiness (he’s a big boi, okay?)
However, Zenitsu didn’t tell Tanjiro his feelings out of fear of rejection (also because gay relationships weren’t all too common back then)
For Tanjiro, he realized he had feelings for Zenitsu when he forced Tanjiro to look after his injuries (which Tanjiro neglected to take care of)
Tanjiro loved how Zenitsu cared for him and made sure that he would take care of himself
Despite this, they didn’t confess to each other for quite some time
They both ended up telling Nezuko and Inosuke about their feelings for each other
This made Nezuko and Inosuke team up and try to get them to confess (this also made Nezuko and Inosuke fall in love)
They managed to convince Tanjiro and Zenitsu to confess to each other by getting the Hashiras into the situation and having them give their support on their same sex relationship
So on one faithful Valentine’s Day, Tanjiro and Zenitsu finally confessed their love for each other (They ended up being sobbing, flustered messes afterwards)
Now on to more general headcanons!
They are both HUGE cuddle bugs!
Once they are cozy and in each other’s embrace, it is physically impossible to move them until morning
Zenitsu is the little spoon, there’s no debate (I mean Tanjiro’s freaking HUGE!)
Tanjiro’s purring makes him irresistible for Zenitsu
His gentle sound, purring, and soft growls make one of the most heavenly sounds Zenitsu’s ever heard
Picnics in the lush forest are their ideal dates! (Bonus if there’s fireworks!!)
When it come to housework, they both work together to make sure that it’s done
Tanjiro is an excellent cook (his sense of smell makes him an expert) and Zenitsu will never stop complimenting it
We all know that Tanjiro is tone deaf, but i believe that Zenitsu has a great singing voice and Tanjiro will occasionally ask Zenitsu to sing him his mother’s lullaby
Zenitsu gets absolutely flustered whenever Tanjiro compliments him or does something nice for him
Both Tanjiro and Nezuko nuzzle to show affection
So when Tanjiro nuzzles Zenitsu, Zenitsu’s face goes entirely red
Tanjiro sometimes kneads his claws like a cat against pillows, blankets, or even Zenitsu.
Yeah it kinda hurts, but Zenitsu loves it and urges him on
They are both there to help each other
Tanjiro will always comfort Zenitsu when he’s stressed and Zenitsu will always make sure that Tanjiro is doing well and taking care of himself
Despite knowing that Tanjiro will never betray him, Zenitsu still gets INSANELY jealous
He mostly gets jealous when Tanjiro spins anyone else around (he does that when he’s happy) or when he holds someone and purrs to heal them
Of course, no healthy couple doesn’t have no arguing
They don’t argue too often since they usually have great communication, but sometimes they do
When they do argue, they usually have to be apart for a little while
But after they’ve calmed down, they talk about the issue and make the other person understands their situation and tries to fix it
The two major ones they’ve had were about Zenitsu’s jealousy and Tanjiro’s self neglect
Despite this, they always stick by each other’s side
(I hope you’ve enjoyed these headcanons! This ship is my personal OTP for Demon Slayer and I love their relationship!!)
Also I hate autocorrect
Tanjiros design depending on which path he goes down in the fic ‘A Kamado with Demon Siblings’ and a bonus look at my first attempt of making a demon tanjiro for the fic.

An AU where Tanjirou is the demon and Nezuko is the slayer. In my version, Tanjirou and Nezuko went down the mountain together to sell charcoals and handmade herb medicine that the Kamado family began to produce for a while. Tanjirou had sold all of his charcoals so Nezuko told him to return home first while she went to finish her items. Reluctantly, her older brother did so. Now it was already late, and Nezuko had to crash in Saburo's house for the night.
You guys know the drill; she came home to find only Tanjirou alive and had to drag him down to the town when he transformed into a demon. The Kamado siblings then found themselves facing a slayer goes by the name 𝘚𝘢𝘣𝘪𝘵𝘰.
Later on, after being given the chance to prove Tanjirou being a good demon, Nezuko set off on an adventure to find cure for her brother.
Kanao and Kaigaku become Nezuko's friends and they became life time trio
Tanjirou grown attached to Kanao, making the young girl rather flustered at such doting
Nezuko possesses very strong kicks! Her first fight with Kaigaku was resolved with her slamming her foot up to his body part where the sun does not rise.
Kaigaku might not be able to have children, rip.
Tanjirou's Blood Demon Art is Fire Manipulation. He can breath fire and heal people too. His berserk form has a horn pops out of his left part of the forehead where his scar is, and there are flame marks on his body.
Hakuji stabbed Tanjirou to see if the demon would attack him -- never happened.
Muichiro and Yuichiro are alive as the youngest kakushi, Mui being a kind but quiet twin while Yuichiro is the loud but anxious one.
The twin have potential to even become Hashiras but Yui keep refusing, only becoming Kakushi because feels indebted to Mitchikatsu who saved them before.
Muichiro wants to become a slayer but doesn't have the courage to say it to his twin.
" Follow your heart! " Nezuko said to Muichiro, resulting the boy to fall for her.
Tanjirou once headbutt Yuichiro for his foul language and harsh treatment to Nezuko
Muzan is still an asshole but he's a tsundere that secretly worries for his slayers
Kagaya is also still gentle and soft spoken but he's very manipulative to his Uppermoons
Giyuu is dead lol, he was the ghost boy that helped Nezuko trained
Sabito and Makomo are both Water Hashiras
Gyomei is Uppermoon One, but there's an Uppermoon Zero, which is Yoriichi.
Yoriichi looks like a porcelain doll with 3 pair of arms.
I might do some changing, but these are what I could come up with so far.
