So Aizetsu is a demon but not a real one just is a clone who is in a group with 3 other clones. Sekido who is anger, karaku who is pleasure, urogi who is joy, and Aizetsu himself who is the manifestation of sorrow. They come out when Hantengu is beheaded the first time, Hantengu is the real body of all 4 of his clones & the clones are all made up from the same cells & stuff as him but look different they are manifestations of his emotions. Hantengu is a upper moon demon 8 upper moons are a group of the strongest demons so his clones are extremely powerful & protect Hantengu because if he dies so do they Aiztesu talks very softly and rarely ever raises his voice and has dark hair is messy at shoulder length but despite his sad behavior and personality he isn’t afraid in battle he’s just sad still fights, his outfit is a dark navy-blue kimono which is like a track suit with long sleeves and separate pants with stripes on them a few tiny bows on the torso area on the front side to keep it closed like a shirt & he only wears socks not shoes & he wears on his back a a nio dasuki which is a rope like accessory and his sclera is a blue & his Iris’s are blue & his eye has Japanese lettering in them that says upper four which shows his strength but also has the lettering sorrow on his tongue showing what emotion he is & has a pale brownish skin color, he has sharp fang like canines but are not noticeable unless he shows his mouth open & he has two normal sized horns on his head that have cracks in them, he carries a Jūmonji Yari & when he uses his blood demon art called weeping spears he can thrust the spear and create long ranged high speed & deadly projections of the attack that can also pierce from a distance, since the clones are all made up of the same demon just in different bodys and are his emotions they all act kinda like Hantengu all in one way, they are hypocrites who don’t take responsibility for their actions and constantly play the victim, Aizetsu sees himself as someone merciful by ending others quickly & he self pity’s himself as someone and wronged and seeing demon slayer as the wrong ones for killing demons but his hypocrisy shows when he must kill because he acts with pity but has no hesitation to kill if needed, Demons need to eat humans to live Hantengu himself is just a coward who can’t fight without his clones & acts like a victim no matter what. Aizetsu’s spear is made through flesh manipulation so he can materialize it out of his palm if he wanted to & he uses his spear with deadly fast speed since it’s light to use and Aizetsu has elf ears & has eyeliner The time period is in Japan in the Taishō era period which is 1912 to 1926.
So Aiztesu had been out hunting and killing like usual. He had been a bit reckless though. He wandered off alone after getting hungry because the other clones kept fighting and making hard to find food since karaku kept play fighting with urogi and messing with Sekido which led to Karaku being slapped but Karaku laughed it off like the little shit he was. Aizetsu wasn’t there for it of course since he wandered off ages ago but still he heard it from miles away. He was strong and could fend for himself but after killing one particularly stubborn slayer and eating them he started losing the feeling in his legs after a bit because the slayer he killed had stabbed his leg in the side with a mini pocket knife when he wasn’t aware and it was covered in some poison so now he was just hopelessly limping and trying to get around. The poison that the mini knife was coated in had an awful lot of it on and was heavy a heavy amount
He was currently limping in the middle of the woods not knowing what to do and felt hopeless not knowing when it would wear off but wasn’t necessarily worried about dying since he knew Hantengu (who is the main body) was somewhere safe and if Aiztesu was to be decapitated he could just regenerate what he was really worried about was burning in the sun (since demons die and disintegrate when in the sun) because he would have to go through all that agony just feeling his skin burn up without the relief of death
