|| Demon Slayer Swap AU react to Swap Giyuu as "He's my man" ||Read the desc|| made by marijuana

Hello, marijuana here. I'm making a really big and long au for kny swap au and kinda bsd? Let me explain. It's really long and I hope you have enough patience to read all of it. Anyway, it starts with swap au (I'll explain characters with Their appearance) and obv slayers are demons. It's a giyuu-centric au. And giyuu is really old in this au. He's one of the first demons. Giyuu saw his sister's death and the village called him crazy. He went to a mental hospital and lost his mind cmind completely. He burned the whole hospital And get lost in the woods. It was winter so he ended up getting hypothermia. On the verge of death, Ubuyashiki found him And turned him a demon. After turning him demon ubuyashiki realized he's not that strong on regenerate. He can't heal his wounds easily like other demons. (and ubuyashiki He developed an obsession with giyuu) He fed giyuu with only his blood. (giyuu didn't kill a single human after Turning demon.) he hide giyuu in the castle for a long time. After turning a lot of human into demons. Uppermoon hierarchy began to shape. Giyuu is strong in combat but he's fragile. So he ended up upper 3. He was Silent and no problematic demon in meetings. He was sitting next to ubuyashiki And resting his head on ubuyashikis lap. Others are mean and really harsh to him. Everyone being mean, Giyuus had no choice but to stick to the ubuyashiki. He wasn't mentally stable enough to Choose wisely or get something on his own. He was abused by Ubuyashiki and some other demons. After kanae died, ubuyashiki matched giyuu and Sanemi together. Sanemi sees kanae in giyuu but giyuu is not kanae. After spending time with him, Sanemi hated giyuu. He looked like kanae but he had The opposite personality. Kanae was funny, intimidating, little rude and really hard to be bored around her. Giyuu was quiet, submissive, boring and unstable. Sanemi hated him with every piece of himself. He despises giyuus whole existence. He abused him repeatedly to break him completely. He thought if giyuu dies he would be free. It worked but not in the way Sanemi wanted. Giyuu completely lost his mind and Killed Sanemi, burned place down and escaped. He ended up with slayers and they experimented on him. (Giyuu volunteered) after really long time ago ubuyashiki defeated, they gave giyuu same medicine that they gave to tanjiro but it didn't work as Expected. His demonic look turned into humanish look and he can walk under the sun. His blood demon art turned into a ability. (bsd abilities yeah) (basically it's giyuu as Fyodor Dostoyevsky.)
