Two young adults could be seen walking through a dark forest. The man is tall and decently built with black hair, brown eyes, and brown skin. He was wearing a white shirt and jeans with brown shoes. The woman next to him was incredibly beautiful with a chocolate skin tone and black hair done into braids. She had pretty blue eyes that looked like gems and fox ears with a fox tail. She was also clearly pregnant, about 6 or 7 months. They were walking through this forest towards a party.

The woman is Diamond and the man is Connor. They have been dating for about 3 years and have been going strong. They have even gotten married a year ago. This is their first child and they are excited to see what it would be like to be parents. They were walking through the forest to get to a party thrown by some friends of theirs, which happened to be held in an old temple. Diamond was already tired from the walk but was trying her best to keep up with Connor. Suddenly, Connor heard a twig snap behind them and spun around, causing Diamond to jump slightly.

Connor: *worridly* Diamond? What's wrong?

Diamond: I'm just a little jumpy is all. We have a bun in the oven and I don't want anything to happen.

Connor kissed her forehead, making her ears wiggle.

Connor: I promise nothing bad will happen. Let's keep going.

They continued walking until they made it to the party. It was quite the sight, with flashing lights and people dancing all over the temple. Connor and Diamond looked around and saw their friends waving at them. They waved back and went towards them. They joined the dance party and were having the time of their lives when disaster struck.

Diamond: *slurring* Oooh! I think I'm gonna throw up!

Connor: *worried* Oh my god! Diamond are you alright?!

Diamond: *slurring* I think I'm going to be sick!

Diamond stumbled over to the bathroom with Connor in tow. She opened the door to a stall and knelt down before throwing up in the toilet. Connor held her braids back and spoke in a worried tone.

Connor: Diamond you shouldn't be drinking, you're pregnant for fuck's sake.

What if something happens to the baby?

Diamond: *slurring* I know, but I couldn't help myself. I wanted to have fun, I'm sorry.

Diamond then threw up again, this time blood came out. Connor got even more worried.

Connor: *worried* Diamond! What's going on? Why are you throwing up blood?!

Diamond: *slurring* I don't know, I just feel sick.

Suddenly there was a knock on the door. Diamond looked up at Connor with tears in her eyes.

Diamond: *slurring* Please answer the door for me.

Connor looked hesitant but then went over and opened the door. He looked out and saw one of their friends.

Friend: Hey is everything okay?

Connor: No.....Diamond's throwing up blood and it's bad. She's pregnant.

The friend looked worried.

Friend: I'll get the party organizer, they can help.

The friend ran off and Connor looked at Diamond worriedly. Suddenly she let out a scream of pain. Connor immediately rushed over to her side.

Connor: *worried* Oh my god Diamond! What's happening?!

Diamond: *screaming* I don't know! Oh my god it hurts!

Connor held her as she screamed and screamed until he heard footsteps outside the door. He looked up and saw a woman in a long black dress come in with their friend.

Woman: *calm* What's happening?

Friend: Diamond's pregnant and she's throwing up blood and screaming. I thought you could help.

Woman: Have you been drinking?

Connor: Yes, she's been drinking all night. But why is she throwing up blood?

Woman: It's because she drank too much alcohol made specifically for this party. Her body is rejecting it. I'll get her to a doctor.

The woman went over and picked Diamond up and carried her out of the room. Connor followed and saw them go into an unknown room. He heard the door close and tried to follow them but found the door to be locked.

Connor: *worried* What's going on? What's happening to Diamond?

He waited for hours and suddenly heard the door unlock. The woman came out with Diamond on a stretcher. Diamond was passed out but she was breathing.

Woman: *calm* She will be fine, no need to worry.

The woman took Diamond somewhere with the men holding her on the stretcher. Even with the reassurance, Connor had a bad feeling about everything so he followed them. He saw them take her deeper into the temple, only making his worry increase. They went deeper and deeper until they came across an altar in a dark room. The altar had a statue of a god, a man with four arms and a head like a serpent's with horns atop its head. Connor had seen pictures on a conspiracy website but wasn't sure who this god was.

Woman: *chanting* Slaanesh, we offer you this sacrifice. Take her soul and give us your power oh Prince of Pleasure.

Connor knew this woman was trying to kill Diamond. He tried to rush over to stop her but suddenly felt a cold sensation in his neck. He looked up and saw one of the men holding him with a dagger in his hand. He tried to fight but the man was too strong.

Man: You're coming with us.

The woman put Diamond on the altar and cut open her stomach, making her scream in agony. Connor yelled in anger and tried his best to escape the man's hold, but it was no use. His Quirk wasn't strong enough to fight back.

???: Infuriating isn't it? The feeling of inadequacy in the face of torment~?

Connor heard a teasing voice that sounded like a mixture of a sultry woman and a charming man with an echo-like effect.

Connor: W-what?

???: Your name is Connor correct? I am the God Slaanesh. I have been watching you. You two are perfect for me. You and your wife are hedonists, don't deny it~. You love to feel good, don't you~?

Connor: W-who are you?!

Slaanesh: I am the one who can give you what you want. The feeling of true power~! You'll never be weak again. The feeling of inadequacy will never plague you again~.

Connor: I.....I just want my son.....

Slaanesh: What?! I offer you pleasure beyond your wildest imagination and all you can think about is a child?

Slaanesh sighs but speaks once more.

Slaanesh: I have an offer for you mortal. Accept and I will grant you your son's survival but at a price. If you refuse, you and your wife will be my sacrifice.

Connor looked down at Diamond and then looked back up at the statue of Slaanesh. He saw the dagger coming down towards Diamond's stomach and made a choice he would regret forever.

Connor: Fine. I accept your offer. Just save my son.

The dagger stopped its descent and some.....thing stabbed the woman through her back. It looked to be a mix of man and woman with lilac skin, stringy black-purple hair, and a gaunt but androgynous frame. Its digitigrade legs ended in claw-like hooves as twisted horns sat atop its head. It kicked the woman off its pincer arm and licked the blood before going on a sadistic killing spree. Connor saw it stab a man in the throat and then saw the blood spurt out, spraying everywhere. The man then fell to the ground dead. Connor felt a few drops of blood land on his face and tried to wipe them off but found himself covered in blood. He was horrified and disgusted by what he was seeing. Slaanesh then spoke again.

Slaanesh: As you wished, you will have a son and he will be strong. You will live your lives in pleasure and give me that which I desire, but at a price. Your son will be different than you expect. He will be my tainted, born of your loins and twisted by my power~! You could say he's OUR son~!

The thing got some of Diamond's blood and rubbed it on the statue, making it glow a myriad of light blues, pinks, and purples, making Connor cover his eyes. The light died down to reveal Diamond, fully healed with no marks of harm save the discolored scar on her pregnant belly. Her baby was safely back inside of her as she cradled herself, crying softly. Connor walked over to her and she hugged him, still crying.

Diamond: I wanna go home.....I'm sorry for this......it's my fault

Connor: *hugging back* Shh. It's not your fault.

The two of them left the temple, holding each other tight. Connor knew his life was over. He would spend his days in sin and depravity, praying for the day he could die and escape Slaanesh's wrath. He knew he would have a son but it would be his greatest curse and his greatest blessing. Slaanesh then spoke one last time.

Slaanesh: My mortal servants~. Your son will be destined for greatness. I'll ensure he is molded into the perfect young man so long as you both indulge in the sickest of pleasures~.

Connor and Diamond were fast asleep in their bed after a night of passion. Suddenly, a cute blur pounced into their bed with a childish giggle. The child in question has brown skin like Connor and Diamond, but he is a smidge darker than them. His hair was a purplish black color that had feint light blue highlights with some pink here and there. He also had fox ears the same color as his hair with dark orange tips. His nine fluffy fox tails had a similar design, but they started off as a light purple and faded into dark purple, which then faded into a black ring with a dark orange tip. This was Dimitri Ambrose, the son of Diamond and Connor.....and Slaanesh by a minute extension.

Dimitri: Mommy, daddy! Today's the day we see what my Quirk is!

Diamond and Connor woke up, Connor yawning.

Connor: I guess we have no choice.

Dimitri: Yay! Come on! We have to get ready.

Dimitri jumped off the bed and ran off. Connor and Diamond looked at each other, a look of worry on their faces. They had seen strange things happen since Dimitri was born. He would always make people go crazy when he was around. Connor and Diamond thought it was because of Slaanesh. They knew they had to hide their hedonist ways to prevent Dimitri from becoming like them. It didn't help that they were in well-paying careers with Connor being a lawyer and Diamond being a surgical nurse. They had to be careful not to let their vices get the best of them or it would be bad. They knew Dimitri was a blessing, but didn't want that blessing to become a curse.

Connor: I don't know how much longer I can hide it.

Diamond: Don't say that. We can't let him become some kind of sick pervert.

Connor: I know but he may end up that way with or without us hiding it. I think it's best we tell him when we tell him about the birds and the bees.....

Diamond: So......puberty?

Connor: Puberty.

The two put on their clothes and managed to get their hyper son in the car before driving to the hospital. They walked into a waiting room where a man with spiky blond hair and a beard was waiting.

Man: Oh hello! Are you the Ambrose's?

Connor: Yeah we are.

The man stood up and shook their hands.

Man: I am Dr. Smith. I'll be the one checking little Dimitri for his Quirk. Though looking at the ears and tails, I have an idea of what it does.

The parents chuckled as he made the joke. Diamond kissed Dimitri's cheek as they went to the waiting room, leaving him in Dr. Smith's care.

Dr. Smith: Okay young man, let's see what you've got.

Dimitri nodded excitedly as he held out his hand. Dr. Smith pricked his finger a took some of his blood before putting it in a machine. After a few minutes, he looked at the results with some confusion. He ran a few more tests, giving Dimitri a sort of rudimentary physical, got a spit and hair sample from him, and even did a small x-ray on him.

Dr. Smith: Hey sport, why not go to the play area? And can you tell your parents to come in here, I have to talk to them.

Dimitri smiled and nodded before he left. Minutes later, Connor and Diamond come in with the former looking confused and the latter looking worried.

Dr. Smith: Can you tell me what your Quirks are? And your parents and grandparents?

Diamond: Well I have a Quirk called Foxy, which gives me these ears and a tail and the abilities of a fox. My father had a Quirk that lets him turn into a dog and my mother had the same Quirk as me.

Connor: My Quirk is called Trial. It lets me detect the signs of a person lying like sweating, heartbeat, pupils, etc. My mom had a Quirk that detected lies and my dad has a Quirk that lets him read minds, but only the mind of someone he touches.

Dr. Smith: Yeah well.....usually I'd advise a divorce lawyer because the wife cheated-

Diamond: -Hey!

Dr. Smith: But all the tests came back and said you two are his biological parents. His Quirk on the other hand.....

They looked at him with worry.

Dr. Smith: Mr. Ambrose, it basically skipped you entirely.

Connor:.....wait what?

Dr. Smith: His Quirk gives him fox traits like Ms. Ambrose, but he has a few odd abilities as well. *looks at notepad* Apparently he can manipulate pheromones, make illusions with said pheromones, manipulate balls of blue fire, grow claws, and even turn into a fox.

They think back to Slaanesh and how she mutated their child as part of the deal. It was something they had to keep secret else Dimitri could be taken away from them and they could be labelled as insane. They had to keep it together if they wanted to keep their son safe.

Connor: Well that's quite the Quirk. He sounds like a talented boy.

Dr. Smith: Oh he is. The only problem is that his Quirk seems to be....ahem....a little mature for his age.

Diamond: Mature?

Connor: Oh......well, how can we prevent those....things....from happening?

Dr. Smith: *laughs nervously* Well, he will most likely have mood swings, maybe some outbursts. He will be very social and friendly but with a....certain....edge to him. I recommend you get him in therapy and put him in classes that teach him to control his Quirk's psychological effects. I can get you a note to go on his record for his school if needed be.

They nodded solemnly as Dr. Smith continued to speak.

There was a lump under the covers of a rather luxurious-looking bed. It moved around before the covers came off to reveal an older, handsome Dimitri. He grew his hair out and styled it into braids. 

Ever since he got older and understood his Quirk, he's been curious about the body and the things it could do. He has also become a bit of a hedonist, just like his parents. He couldn't help it as it was in his blood. He got out of bed and began to get dressed. Usually, his clothes were mostly flashy, flashy being a fitting word. They were always brightly colored with lots of designs on them. However, he had to put on a school uniform as it was his first day at U.A. High. He got in on a recommendation from Mt. Lady, Midnight, and Uwabami so he just had to do a mock entrance exam and passed with flying colors. After putting on his uniform and adding a few accessories, namely some earrings and a choker, he blew himself a kiss and went downstairs.

He saw his parents in the kitchen eating breakfast. His father was a decent man with a strong jawline and a five o'clock shadow. His mother was incredibly beautiful and seemed to get prettier with age. They were both in their pajamas and were chatting when Dimitri entered.

Diamond: Hey sweetie. Good morning!

Dimitri: Hey mom! Good morning! I'm going to school now!

Connor: Be safe at school!

Dimitri nodded before going outside. He took a running start before getting onto all fours and quickly shifting into his fox form, which was about the size of a Great Dane.

He ran through the streets of Musutafu, bobbing and weaving past pedestrians and traffic. He made his way to U.A. High School and saw the giant building in front of him. He stopped at the entrance, shifted back into human form, and walked in. He saw some of his classmates and greeted them with a smile and a wave. Though he was a new student, he's already garnered the attention of students from all three years due to being new so late in the year and because of his looks. As he walked through the halls, Dimitri gave a seductive smirk as he licked his lips.

Dimitri: My my, so many tasty morsels to sample~.

Snapping out of his horny thoughts, he knocked on the door. A scruffy man opens it and looks up at him due to Dimitri being 6'2.

???: Are you the new student?

Dimitri: Perceptive, but yes.

???: I'm Shota Aizawa, your homeroom teacher. Come in and meet your classmates.

Smiling, Dimitri followed his teacher. When he did so, all eyes were on him. Everyone was either curious or starstruck by his sweet smile.

Aizawa: Class this is Dimitri Ambrose. I know it's a few weeks into the school year but he was recommended by three pros.....*mumbles* even if they're glorified models.

Dimitri: Buongiorno~.

Dimitri smiled and waved at his new classmates, his seductive tone eliciting all sorts of reactions. He sat down at his desk, which just so happened to be next to Izuku. They both smiled at each other before class began. Dimitri listened intently, his Quirk making it hard for him not to pay attention. He was so attentive that his Quirk decided to help by making him feel pleasure whenever he learned something new. Aizawa looked up at the ceiling for a moment and continued speaking, trying to ignore the odd feeling that suddenly made him warm as well as ignoring the lingering strawberry scent. 

Dimitri: 'I think I'm going to like it here~.'
