Jadith was the bastard child of a royal woman and her male escort in the Diamond kingdom (kingdom in Black Clover known for shady ass sh*t.) Not wanting the bastard child to ruin her image, the mother sold her into (triggering content ahead) sex trafficking, not only to get rid of the child but to profit off her as well. Jadith grew up being rented out and raised to please. She was marked with a magical rose tattoo on her back to mark her as a royal escort and a enchanted collar to keep her controlled and to track her. Not being allowed to look into the eyes of any man that wasn't her current owner, speak unless spoken to, or use her magic. She was sometimes rented for long travels and journeys to keep people *entertained.* On one of these journeys, the destination being a black market trade with the clover kingdom for enchanted goods, it was intercepted by the Black Bulls magic knights squad. They saw the state she was in and when defeating the cartel, offered to free her which she gladly accepted. Asta was able to release the spells on the tattoo. During the battle, some of the members of the black bulls were almost injured which spurred her into action. She was able to summon her grimoire for the first time, and found that she had blood magic. After the fight, they offered her a home in the clover kingdom with them. She was scared of trusting them, but she gave it a shot. From there, the team worked on acclimating her to speaking, eye contact, making friends, platonic touch and training her to use her powers. After a year, she took the magic knights exam to attempt to earn a spot with the Black Bulls, having grown very attached to her new friends.

So Kenneth was born as girl named Kerrie, and was traumatized sexually as a child. (Like me, I am using Kenneth as an outlet to myself and my lust because I became scared of sex and frequently the other option for sexual trauma typically has people becoming whores) Kenneth lashed out and decided to numb herself to life by having tons of casual sex and getting addicted to drugs like coke and ecstasy because it indulges the pleasure of sex. The addiction got so out of hand that she eventually started selling her body for the drugs because she couldn't keep up with the cost. This got her into an even more dangerous life causing her to be raped and beaten. She ended up reliving her past she was trying to numb herself from and OD'd. She was sent to hell for her sins and there she just sat in cried. Lucifer pitied her, and instead of damning her soul, turned her a demon of lust. With the power of demons, she became able to morph her body, where she took on a more masculine appearance and began to go by Kenneth. Now, there are multiple universes with Kenneth as I have used him in different scenarios with different people and such where he lives out his life as a succubus essentially and just f***s a LOT. Either with a d*ck or a p**sy.

However I have a true ending for him based of this person's oc I used to ship Kenneth with. They had this adorable Angel OC and I loved the two of them together so I created an ending based off that dynamic.

Kenneth one day gets summoned by a horny girl who is seeking out magic and demonic energy. And what better than being f***ed by a horny demon. He saw himself in this girl and began to look over his life as a demon realizing he learned nothing from his mistakes. He lectured the girl and tried to get her to renounce casual sex because it leads down a dangerous path. An angel had been sent to save this girl after she summoned a demon, but the angel seeing Kenneth lecture her instead, waited for Kenneth to leave. He found Kenneth interesting and wanted to talk to him since he had never seen a demon with morals.

So Kenneth was about to leave back to hell/purgatory when he noticed the Angel who was beckoning him to come outside. They began to talk and Kenneth really liked this angel. They talked for hours about life and heaven and hell and the human world. Kenneth asked if they could be friends still, even if Kenneth went back to hell and the Angel to heaven. The Angel asked if he would just like to come to heaven instead. Kenneth was really scared, but the Angel assured him that everything would be okay if he would renounce his lust just as he lectured the girl to do. They went back to heaven together where he was summoned in front of God to share his story and defend his convictions.

He was baptized then and became born again. It was an extremely painful process, but it gave him the comfort of faith and allowed him to resist his urges, but they were still there. He lived with the Angel, helping him, and falling in love with him. It was so hard to control his urges with this beautiful Angel. There were many times where he got close to breaking and taking what he wanted but he held himself together. The Angel noticed this very obviously as he was falling for Kenneth too. So he went to God and asked if they could be married with his blessing. This would allow the Angel to give Kenneth everything he wanted while still remaining holy. With permission, the got married and had an amazing sexy honey-moon yippie
