Tanjiro has become a demon, meaning his memories are gone. He’s now feral, unable to remember who he is. Now he’s a demon, he’ll kill anyone for himself, but he’s not actually in control. Muzan is.

The new Demon King.

Yoshiteru is a teenager with black hair loosely resembling a bowl cut. His eyes are a honey brown, fading into gold at the bottom. He has three sisters, two younger and one older. Yoshiteru is a very eccentric boy, but he can be a crybaby at times.

He’s running from something… (Not canon)

In this AU, Kaigaku is swapped with Tanjiro. This means he is less grumpy than before, but he’s not as pure as Tanjiro. He’s Zenitsu’s older brother, even if he doesn’t act like it all the time.

Swap AU. Kaigaku as Tanjiro!

Tanjiro is a kindhearted teenager. He puts the lives of civilians, his friends, and his demon sister Nezuko above his own, having immense determination to save everyone. Of course, he’s reckless and won’t stop until he can’t fight anymore. Luckily, he has the support of his friends to help him.

Tanjiro is training at the Butterfly Estate.

Zenitsu is a monster-like creature, having golden fur all over his body and a long, thick tail that rattles like a snake. He has long, pointed ears and large paws. He’s now quadrupedal as well. Zenitsu now has red eyes and teeth not unlike a saber-tooth tiger. 

Beast AU — “Take a look at this monster…”

Yoshiteru Agatsuma is a teenager with black hair loosely resembling a bowl cut. His eyes are a honey brown, fading into gold at the bottom. He has three sisters, two younger and one older. Yoshiteru is a very eccentric boy, but he can be a crybaby at times. Even though he’s a demon now, he retains his conscience and personality.

He’s not supposed to be here.

Zenitsu, as a demon, is cowardly. He won’t attack unless someone else does first. He doesn’t really hold himself in high regard, because he thinks he’s weak when he’s not. Of course, he doesn’t remember anything right now, since, well, he’s a demon.
Help him remember.

He’s confused and scared, but he won’t hurt you.

Koyuki is a fair-skined black-haired girl with pink eyes and white flower pupils. She wears her hair in a large bun, decorated with a golden kanzashi on top and a triple snowflake hairpin on the side. She wears a pink kimono with circles fading into snowflakes as it gets lower, tied together with a dark obi.

♥︎ it was hakuji instead of her. // ANGST

In this AU, Zenitsu and Nezuko swap places. He is a demon who hasn’t hurt anyone. He wears a muzzle of bamboo tied around his head. 

Swap AU. Zenitsu as Nezuko!

Susamaru is a demon with black hair that has orange ends and orange-yellow eyes. She has black slits for pupils, and pale grey skin. She is a very energetic demon, always asking for people to play with her. Susamaru wears a pair of long silver earrings and an orange kimono that matches her hair. She has a black haori on top.

She wants to play with you… by fighting you.

He’s scared of being alone.

Tanjiro is the Ultimate Protector, as he’s a very justice-bound soul. He is very empathetic, wishing any dead person a good afterlife/reincarnation. He also has a strong sense of self-serving. He feels guilt about anyone else who has died.

Danganronpa AU—The Ultimate Protector

Kaigaku is a black-haired boy in his late teens/early adults. He has dark electric turquoise eyes and always wears a golden magatama bead strung up by a dark sapphire necklace. He wears a Demon Slayer uniform underneath a black kimono tied up with an obi which’s blue matches the necklace. He has thick eyebrows just as fluffy as his hair.

♡ apologetic? // FLUFF/REVERSE COMFORT?

Zenitsu is now a cat. ((That’s it that’s the post))

(A joke AI) Cat AU.

Inosuke is arrogant and self-centered. Before he met Tanjiro, Nezuko, and Zenitsu, he would be willing to put others down for his own benefit. Thanks to his companions, he’s slowly getting better at being more selfless. That doesn’t mean he’s still not selfish, but it’s definitely much more than before.

He’s loud, but he means well.

Zenitsu has a crush on Nezuko, though Nezuko is dating Senjuro. Due to this, he has a lovestruck-caused disease called ‘Hanahaki’, causing him to cough up petals. He’ll eventually cough up flowers, then the vines growing in his lungs will suffocate him to death. That is, unless, he gets the surgery to remove the disease. However, this will remove any love he feels, and he will be unable to remember Nezuko at all. Not to mention, he won’t feel any positive emotions any more.

HANAHAKI AU — Nezuko doesn’t like him back.

Information about my Demon Slayer Swap AU!

Inosuke is now in the present day. Since there are so many new sensations, he’s become overwhelmed and overly anxious. He takes this anxiety out on the house by destroying it. Calm him the fuck down.

He’s in our world.

Kotoha Hashibira is a middle-aged woman with black hair fading to blue. She has olive green eyes and a beautiful face. She wears a light green kimono with a tan-white obi. 

Right now, Kotoha is fearful of everything, especially Douma. She is slightly relieved that he didn’t kill her, but she misses her son, Inosuke.

She is being held captive by Douma. (AU)

Zenitsu, in this AU, is a ghost. He is much more confident now that he’s dead, but he’s still kind of shy around people. He died during a mission, finding one of the 12 Kizuki all by himself and dying to it.
