Notes: Hello guys! Welcome back!

I had some trouble writing this chapter because I had direct contact with some coworkes that were infected with corona virus, and the fear caused me to have a mental breakdown. I'm still waiting to see if I'm sick or not... But yeah, gotta keep living, since my boss don't fucking let me stay at home.

Anyway, I'm sorry for the delay! I hope you like the update! The comments make me happy and give me strength to keep going. Don't be shy!

I gotta thank my friend Sabrina for helping me by reading the chapter before the update and giving me tips and opinion! Thank you, girl!

Sorry for the mistakes, me and Sabrina tried to find them, but we are Brazilian so our English isn't perfect.

Enjoy!

Chapter 6

Undefined date – 09:40

Capulet City

"How are you feeling?" Nero asked in a low tune, rearranging Kyrie's messy hair behind her ear and pulling her closer to his chest, hugging her tighter. Kyrie was still flush against him: she was sitting on his lap since he didn't want to let her go, not even when she woke up. She tried to stand up by herself a couple of minutes ago, but Nero gave her puppy eyes and she simply sighed and asked for a cup of tea.

Nero literally heated up the water and prepared everything with her firmly in his arms, using the spectral wings to do the handwork in the kitchen. He feared that, if he let her go for only one second, she would faint once again.

It was an irrational feeling, but Kyrie always says he should always follow his heart. He was just following her advice (that's what he told her when she tried to stand up one more time, and she couldn't argue with him on that – she only pouted, and he would laugh if he wasn't so worried about his girlfriend and baby's health).

It was true that Kyrie loved Nero's overprotective side, but she thought that since the twins were back, Nero should talk to them, and let her alone for a while. She just wanted to lie down in the double bed that Nero had put in the spare room (from what he told her, the former storage became a guest room after Patty's insistence, since the girl thought it was absurd that Dante didn't have an appropriate room to receive visitors), and rest until... Well ... Until the pregnancy ends, probably.

She was so, so, sooo tired. It didn't help that Nero was always agitated when they tried to sleep, wanting to be with her at all times but interrupting her sleep with agitated gestures during his dreams. He behaved like her complete opposite: full of energy and anxious about it.

Kyrie wondered every day if coming to Capulet had been a good choice, because after they arrived, Nero seemed more and more agitated, while she was feeling more tired every passing minute.

"I need to sleep, Nero" She spoke sleepily, holding the cup of tea with both hands in an attempt to not knock it over again. Nero had given her another cup a while back, but she felt so drowsy that she dropped it on the floor.

"Babe, how could you sleep after what happened?" Nero asked, dumbfounded, hiding his face in the fold of Kyrie's neck and sniffing traces of Vergil's scent on his girlfriend. He was going to kill him for getting so close to her "The idiots are here, Vergil is here, and you know very well what he did the last time we met him, and...-"

"It is not very polite to speak behind someone's back, boy." Vergil, ironically, spoke behind Nero's back.

The younger acted on instinct: he took the cup of tea from Kyrie's hands and threw it hard towards the door, and Vergil took a short step to the right and dodged the attack.

The sound of glass breaking caused some commotion on the upper floor.

"STOP DESTROYING MY PROPERTY!" they heard Dante shout from the mezzanine, probably not wanting to get down and talk to Nero face to face.

As always, the idiot is running away from serious business.

"THIS IS NOT YOUR PROPERTY, IT'S RENTED!" Nero shouted in return, and he could swear he heard Vergil chuckle (Maybe I'm hallucinating or something). Dante didn't answer while they heard heavy footsteps from above. Perhaps, by some divine miracle, Dante was trying to organize the mess in his room a little bit "ALSO, YOU OWE ME MONTHS OF REFUND, DANTE!"

"A charming guest as always!" Dante spoke and Nero almost didn't hear, but his devil hearing was really on point "Miss you too, kid!"

"DOUCHEBAG!"

When the shouting stopped (and Kyrie laughed at the nostalgia of witnessing the two of them bicker as they used to do), Vergil seemed to consider that it was safe to approach the couple as if nothing happened. And so he did it: he crossed the kitchen gracefully, took a cup from the dish rack, and serve himself some hot tea from the kettle; after that, he sat at the tiny kitchen table,
staring penetratingly at Nero's eyes, and took a sip.

"Lavender tea" he hummed, taking another sip and ignoring Nero's incredulous look. The younger seemed very stunned by witnessing someone like Vergil, who was always related to blood and destruction, doing something as casual and refine as drinking tea "A good choice."

"Thanks!" Kyrie casually replied, as if she wasn't scared to death of that man a few minutes ago; Nero felt even more incredulous "It's my favorite."

"What's wrong with you people!? Kyrie, don't chit chat with this idiot!" Nero scowled. Was he in some parallel dimension or something? Why Vergil was acting so casual after all that happened?

"Actually, we shouldn't chat per se, since I am the one that need to speak here." Vergil replied casually, resting the cup on the table and crossing his hands over his lap. He looked sharply at Nero in a gesture of curiosity. After what seemed like an eternity, he sighed, took a deep breath, and finally said "I was... exalted."

Nero waited a couple of seconds, until it was clear that Vergil didn't intend to say anything more.

"Is that your asshole way of saying an apology?!"

Vergil hummed before answering, still maintaining his blasé expression.

"It is the closest to an apology you will ever receive from me, so deal with it."

"Now I am sure that you really are Dante's brother, even if you two demonstrate your 'assholeness' differently, but I can see the similarities Mr. I'm-never-wrong." Nero scoffed "What makes you think that I will forgive you and act as if nothing has happened?"

"I believe that I am the only person able to answer many questions that you have. Among them, the reason why your girlfriend has been so exhausted lately." Nero and Kyrie visibly tensed over that statement, and Vergil knew he had hit the jackpot "Believe me, boy, you will need my help."

"I... I can ask Dante all of that!" Nero tried to argue, but Vergil smirked in return.

"Dante didn't carry you for nine months. He doesn't understand the struggles."

"And you do? Come on! Don't be a hypocrite! I'm sure you were never around my mother while she was pregnant! You probably just run away like you always do!"

Oh… how wrong the boy were.

No, Vergil had no intention of speaking openly about the fact that he was the one who had Nero in his womb for nine months. He knew that this conversation would happen eventually, but he was not ready to deal with the consequences that his revelations would bring. If Nero understood that he, as an omega, was the one who dealt with the pregnancy, he would question more about the other parent. He didn't want that right now.

Nico had revealed to V once that Nero believed he was the son of some prostitute from Fortuna, and so he was abandoned in the orphanage after birth, since this was a common practice in that city. Fortuna's orphans either lost their parents in a religious crusade, or were conceived at sex industry. When V heard about this information, Griffon even pinched him to put some common sense in his mind and make him considerate Nero as his kin. Everything indicated that Nero was not just any Dante's cub, but the baby that Vergil left at the orphanage.

V's memories were still murky and dreamlike, but Vergil remembered how V's heart abruptly accelerated with the revelation. As a defense mechanism, however, he chose to continue in denial. V was already too preoccupied with his attempt at survival; he didn't want to dwell on Vergil's past and mistakes, even though he needed Urizen to survive again as Vergil. V chose to let Vergil deal with the consequences of his actions when he was complete again, and didn't think about this any longer.

Now there was nowhere else to run: he could not justify his absence from Nero's life as a way to protect him from Mundus, since Dante had defeated the prince of darkness. He could no longer neglect an affective bond with Nero because he was trying at all costs to survive, as V once had done. There were no more excuses. He had to face everything, including the anger in his cub's eyes, who had the worst possible impression about him.

It hurts, even though he wasn't sure what to do or say so that the boy would understand his decisions.

That's why, for not knowing how to deal with feelings, he was one again silent. To an outsider, Vergil seemed completely composed with his stoic attitude. Nero, in his rage, didn't see his eyebrow twitch and a hurt expression flash trough his eyes by a brief second. But Kyrie was perceptive enough to catch that, so she intervened before things get even uglier between them.

"Nero, please give him a chance." She asked, and Nero could be sure that his girlfriend wanted to say 'He is your father, you should listen to him', but wisely refrained herself and chose another argument "From what you told me about V, he is smart and may truly help us."

"Well, but he isn't V."

"I beg to differ. V may have been my weak human self, but was still part of me. Everything he knew, he learned by my experiences."

Ok, V was Vergil, more or less, but...

Nero could be emotional about this 'parenting' stuff right now, but that doesn't mean that he would automatically forgive all of Vergil's mistakes and accept him with open arms in his life. Precisely because he was experiencing fatherly feelings towards his upcoming baby, and since he loves the orphans as if they were his own kids, he could not understand how Vergil was so selfish to leave him behind. Even though he imagined that his father didn't know he had a son out there (he would have to question Dante about it), he clearly accepted the risk of this happening when he fucked some random woman in Fortuna. And yet, he left without a second thought.

Despite the rancor he felt, Nero gave up the opportunity to argue about it. No, not now. Kyrie was more important than his past, and if he had to swallow his pride for some time to collect the maximum information that Vergil could provide them, he would accept this burden.

"Ok. Spill."

Kyrie tried to move off his lap, gesturing for Nero to place her on his side. Although it was not something Nero wanted to do (he seemed to want Kyrie glued to his body at all times in the past few days), he helped her sit on the chair next to him. She let a faint smile frame her lips in thanks for Nero's gesture, and then turned a gentle but attentive look to Vergil.

As the interaction between the couple happened, Vergil felt foolish for not considering the possibility of Nero and Kyrie being together. The brief time he lived as V in Nero's companion, he never got the chance to meet Kyrie, but he knew that the Sparda spawn had a girlfriend. Nico made fun of the boy's love life a few times, and Nero answered a few calls in the van with a serene and passionate voice, talking very different from how he talked to Devil May Cry's customers. He suspected that they even spoke Kyrie's name a few times, so that's why the name was familiar to him, but V never paid any attention to these details to the point of wanting to know more. V was only focusing on defeating Urizen, so Nero's personal life was not worthy his attention.

How things change... Now that V and Urizen were back together, Vergil was indeed curious to meet the girl. She looked kind and sweet, like her mother was with him and Dante. And it caused him a mixture of feelings and resentments. Of all the women in the world, of course Nero would find a girl who looked so much like Eva.

Ironic, but predictable.

"How long have you been pregnant?" Vergil asked, deciding to get straight to the point.

"Twenty weeks." Kyrie replied, placing both hands in her lap, affectionate hugging the cub in her belly. She had a small bump, but her wider dress could make someone miss the fact that she was pregnant. Now that she was caressing her lap, Vergil could see the volume clearer, and the reality that a new heir to the Sparda line was on the way hit him hard.

Vergil never imagined that the Sparda line would continue beyond his and Dante's generation. He always thought that they would be the last ones, because their blood was tainted by human blood, and hybrids, even animals, are usually sterile. When puberty started bothering Vergil, he was not very young, even to human's standard. He was a late bloomer and, at first, he didn't understand what was happening to his body, so he chose to go to the place where could find all the knowledge he sought: the library. It was at the library that he met Arkham, who eventually leaded him to beginning of his fall.

Arkham taught him about his father, Temen-Ni-Gru, and his nature. Sometimes, Arkham spoke for hours and shared some of his knowledge; sometimes, he lent Vergil some books of demonology for him to learn on his own. Eventually he found out he was an omega, and he hated it with all his might. Not because of the sex dynamics, but because he would always need someone to obtain the vital energy he needed to survive his heats. He didn't want to be depended, not again! His mother left him to die, and he learned the hard way that he could only trust himself and his power to survive.

The prospect of gaining his father's power unleashing Temen-Ni-Gru made him stay at Arkham's mansion while the wretched human searched the exact locations of the seals. He planned to use that power to enslave demons, so that way he could still be an omega and use the energy from the weakened alpha demons. He would be stronger, and he wouldn't become dependent on anyone! He could defeat Mundus, the prince of darkness, and rule as the supreme being he would eventually become!

Yeah, right… That, in fact, didn't end very well.

In the middle of staying at Arkham's mansion and finding out Dante was alive, he had his full heat and succumbed to his need of energy. He mated, only once, but it was sufficient. He became pregnant, and that made him totally lost about his future and his plans. He left Arkham for a while, hiding in Fortuna with the pretest of looking for one seal location and gaining more information about Sparda. His stay at Fortuna was difficult, and he suffered a lot to gain energy to generate his cub healthy. After his baby was born, he returned to raise Temen-Ni-Gru and gain power, not telling a single soul about the new addition to Sparda's lineage. At that time, the motivation to seek power weren't only for him to feel strong and in control, but for his cub safety too. He needed power to kill Mundus, before the demon came to kill his kin – He knew that Mundus was still after him and Dante.

Obviously, things didn't go according to the plan. He never got back to raise Nero, and Mundus tortured him for a long, looong time...

His traumas didn't matter now, not in the present events. But something was true: despite all the knowledge he obtained, something was not right. In his research, he found out that he was probably sterile, and that was proven wrong. When Nero was born, everything seemed so surreal, because he just didn't think it was possible for him to give birth to such a healthy and strong creature. In fact, Nero was only conceived because Vergil didn't imagine that he could produce offspring, since if he had known, he probably would not have yielded to his most carnal instincts with... with... the other parent.

Anyway, even though he wasn't as sterile as he imagined, he was absolutely sure that Nero would be, because, genetically speaking, there were lots of obstacles for this to happen. Nero's genetic is really messed up, much more than the boy knew. Therefore, even if Nero had a human girlfriend, finding Kyrie pregnant didn't immediately make Vergil think the baby could be Nero's. It was only logical to assume that Dante was the other parent, since she was at his territory and he knew that Dante was fertile.

That's not the issue anymore, but the fact that Nero was fertile was sure interesting.

"Kyrie has been acting weird for several weeks." Nero added when Vergil was thinking endlessly. Vergil blinked and regained his focus, and Nero pouted while looking away, probably having difficulties to swallow his pride and ask for any kind of help "She is exhausted."

"Nero, don't be so dramatic, I-" the girl tried to argue, but Nero interrupted her.

"It is not drama. Kyrie isn't just tired, in pain or something like that. She is exhausted, sleeping on her feet, and I don't know what else to do." swallowing his pride, the boy directed a frightened look to his father "I really hope that you know what is happening to her, because I will go crazy if it doesn't stop. Please, help her. I want her to be safe. I love her, so much, and the baby too... And... Just... Please do something. I beg you."

Kyrie didn't try to argue anymore. She just took Nero's hand with her right one and smiled lovely to him.

Vergil, hearing his own son's plea, was speechless: it seems that in that aspect, Nero was very similar to him. He may be possessive and selfish, and he sure was very proud in all possible aspects of his existence, but when it came to keeping Nero alive, he was capable of everything. He did it all for Nero: the most odious things, the most deplorable ones... not even Dante knew what he had to do to keep his cub safe. And apparently, Nero would be like himself in that regard: he would do anything for the sake of Kyrie and his offspring.

Vergil cleared his throat, choosing to end his cub's worry.

"You are together, right?" he asked.

Nero rolled his eyes.

"What a stupid question, of course we are together!"

Oh – Vergil thought – So he has no idea. I'll have to be more... incisive.

"I will refine my question: Are you actively together and copulating regularly?"

Nero's eyes widened and Kyrie blushed so much that Vergil feared for the girl's health. Then he remembered: the two are from Fortuna; and people from that damn island usually never talk about this kind of thing out loud. Vergil himself isn't someone that talks about sex all the time (leave that to Dante), but he certainly isn't like a Fortuna puritan citizen.

"What kind of stupid question is that?!" Nero asked, his voice high and slightly out of control; he jumped to his feet, feeling embarrassment and indignity "What does this have to do with the problem?! I would expect this kind of sick joke from Dante or Nico, but-..."

"Calm down, boy." Vergil raised hand in a gesture of peace and signaled with his fingers for Nero to sit down again; Nero refused to be ordered around and stayed standing "I have no interest in knowing details about your sexual activities, but this question is necessary to understand the preliminary conditions of your mate's pregnancy and find out what kind of problem we need to face. So, I ask again: Are you copulating regularly?"

"No." Kyrie replied; Nero looked outraged at his girlfriend, as if she had just betrayed him by revealing something so personal to Vergil. She smiled sweetly at her beloved, trying to make him relax "Nero doesn't want to."

"T-that's not it!" he defended himself, stuttering. Vergil, finding all the reaction funny to watch, just crossing his arms and appreciated his cub's desperation (he found it cute, but he would never admit such thing) "I... S-she is so weak, and I-...!"

"You are afraid to hurt her. Am I correct?"

The boy, who was expecting to be made fun of, was taken back. He nodded in return, speechless.

Kyrie sighed and took a deep breath, as if in addition to being physically exhausted she was tired of dealing with this problem.

"Nero, I already told you: the doctor said that this won't happen, you won't hurt the baby."

"You don't understand, Kyrie!"

"In fact, neither of you understands the situation, so I suggest you to be quiet and pay attention." Vergil warned and the couple instantly stopped talking "It's natural for Nero to have a rational fear of hurting you, woman, since he is an alpha and you are only lowly human."

"Are you offending Kyrie again!? And what the fuck do you mean with this alpha bullshit?!"

"I'm just stating a fact. You are an alpha and, about that, I suggest you ask Dante for guidance, because he will be able to explain the dynamics to you much better than me. At the same time, the woman is human, at least as far as I can tell. Humans are fragile, and you know it. So, as I said, it is rationally natural for you to be afraid of hurting her. Be frank with her, I assure you that she will understand your concerns better."

Nero looked at Kyrie with a little fearful expression, but took a deep breath, set down again and took the girl's hands with his, staring at her penetratingly as he thought about the best way to put his feelings into words without scaring her.

"Kyrie... I... it is not that I don't want to do... Hmm... 'these things'. I want to, you know I'm crazy about you and... Well, yeah. I can guarantee you that I think about it all the time, and that's the problem. The demon, he just thinks about it too, all the time! He is whispering nonstop in my mind about his needs and your needs in an animalistic way and that's the fucking problem. I don't know if I'll be able to control the demon if we... If... I don't want to hurt you if that happens, Kyrie!"

"That's why you also don't understand the situation, boy." Vergil added, interrupting the couple before the girl could give her answer "You are hurting the human by not giving her your demonic energy. She needs this energy to generate the cub, and you are neglecting one of the alpha's only functions during pregnancy: to be the provider. She is living on the basis of the little energy you give her by being by her side, but her body cries out for more. More energy will only be exchanged through carnal activities. Follow your instincts, boy."

"What-...?"

"Nero." Kyrie interrupted Nero with a docile voice, sweetly holding Nero's jaw with both hands, making him look at her. He seems confused, and she would reassure him the truth as many times as it was necessary "I trust you."

"But… The demon! He-...!"

"He is you, Nero. You! The person that I love and trust with all my heart! I don't care if you're human or demon, I never did and I told you that many times, my love. You are Nero, the one I chose for myself. I just know that you will never hurt me."

Nero was perplexed; he kept looking at her, lost of words. So she decided to make the first move and kissed him fully on the lips. Nero finally surrendered to his instincts and let a satisfied noise escape his throat as he reciprocated the kiss fervently.

Vergil, on the contrary of what one might think, just watched the two lovers kiss and caress each other with analytical eyes, without any shame or judgment by the public display of affection. For someone who has lived in Hell for so long, something like that wouldn't embarrass him. But, if he was true to himself (something that he usually isn't), he felt a little jealous, wishing that he could do the same with Dante.

No. 'Kiss' is something humans do. I do not want to kiss Dante. I want to mate, and just that. – He thought as fast as that foolish desired invaded his mind. Being near humans was making him suffer from side effects, that's all.

When Nero grabbed the base of Kyrie's neck and pulled her closer, Vergil could see that the boy's hair had grown out a little past his shoulders in just a couple of seconds. Vergil knew it would be a matter of time for Nero to let his full devil trigger be released, because the changes in his appearances were already showing.

It would sure happen, if Nero hadn't purred loudly at that very moment, making the couple end their kiss abruptly with a wet smack.

Vergil caught a glimpse of Nero's yellow eyes losing their demonic glow when he blinked fast, confused and lost. While he was trying to understand what happened, his hair was returned to its normal short length, and Kyrie smiled watching the magic body modification happens in front of her eyes.

Before Vergil or Kyrie could say anything, Nero simply ran out of the kitchen in full speed, knocking over his chair in the process and smacking the door behind him. He was confused, scared and overwhelmed, so he did what a Sparda do best: Run away from their emotional problems.

A true heir, indeed.

"Did he just… purr?" Kyrie asked softly, a satisfied smile framing her swollen lips while she still looked at the door, as if she was waiting Nero to come back anytime.

Vergil let out a sarcastic chuckle.

"Yep. Demons do that when they feel safe or happy. Nothing unusual, however."

"It was… It was the cutest thing Nero ever did!" she exclaimed, still in her affectionate state.

Foolish girl... Finding demonic behavior adorable. It's real what they say: women in love are difficult to understand.

When Kyrie stopped looking at the door with dreamy eyes and turned her attention to Vergil, she totally changed her expression: she looked more attentive, a little uncomfortable, and definitely serious.

"I feel a lot better already." She spoke in a low tune, as if she was spoking to herself, not to Vergil.

He responded anyway.

"Kissing isn't near as efficient as carnal activities for exchanging energy, but it is effective in your actual pregnant stage. Just kissing should help you for a few more days, in case he doesn't give in so easily. You'll have to make him submit eventually."

"By 'submit' you mean 'make love', right?"

He scoffed.

"You can call it whatever you want, I don't care."

She nodded while her blood tint her cheeks, a little embarrassed that they were still talking about her sex life.

"Thank you."

Vergil was surprised by her gratitude. But despite her words, Kyrie didn't look as carefree as before, keeping her expression firm and defiant. Vergil could only think of Eva, since his mother used to show that same expression before scolding him for something bad he had done as a child.

Since Vergil didn't say a word, Kyrie kept talking.

"I appreciate it, because without your words I wouldn't be sure what I should do for my baby's health. I want it to grow strong." She rubbed her belly, showing how much she was indeed preoccupied with the cub even before its birth.

"You would eventually find that out on your own." Vergil explained, dismissing her grateful words "Nature is stronger than you think."

She shook her head in affirmation.

"Yes, I agree. But your helpful words sure will spare us from more suffering. I know that's why you decided to speak to us." Kyrie didn't even blink, looking at him so penetratingly that Vergil wanted to follow Nero and run out of the kitchen "However, I haven't forgotten what you did to Nero."

So that's the reason she was looking at him like that. She seems like a sweet girl with a big heart, but she didn't completely forgive him. He couldn't blame her, in her shoes he sure would hit first and ask questions later.

Vergil choose his next words carefully.

"Are you speaking about the Yamato's incident?"

She raised her eyebrow, judging the way he sugarcoated the fact that he ripped his own son's arm like it was a simple 'incident'.

"I mean everything." She concluded, rising from her chair, taking the empty cups from the table and putting them into the sink while continuing to speak, "I am not against giving people a new chance, but I want you to know that I have a really strong memory. Nero may seem tough at times, but he'll forgive you and accept you eventually, because it is in his nature to be kind like that. And that's why I love him… But just remember, I'll be on the lookout for any mistakes you make. Never forget it."

Vergil was astonished, so he just kept watching the girl's back as she started to wash the dirty dishes. What audacity of that human to threaten him like that! As if she was able to offer him any kind of danger! He was a son of Sparda! The rightful king of the Underworld!

"Vergil, the dish towel is hanging by the window." She casually spoke, still playing with fire.

Vergil stood up, holding Yamato's in his hand, his eyes showing an angry scow.

Insolent human!

"After we take care of the dishes, could you please help me with lunch?" she continued to speak, as if she couldn't sense his threatening aura.

And then he finally realized what Kyrie was trying to do: she wasn't trying to manipulate him or order him around; she was simply trying to spend time with him to get to know him better and judge if he was worthy of her forgiveness.

Vergil found his pride stuck in a deadlock: while not wanting to take orders from a weak human, he wanted to create a good relationship with Nero and his family now that he could finally experience it. And, convinced that it was nothing more than his own choice, he released Yamato's handle and approached Kyrie, taking the dish towel and awkwardly starting to dry the clean dishes.

The girl looked at him with a grateful smile on her lips and Vergil, once again, thought of his mother. She sprouted Eva's serene smile, and that smile doesn't seem to morph into a judgmental one like in the picture frame. He may resent Eva for liking Dante more and leaving him behind, but he does love his mother and misses her so much…

Trish may have Eva's face, but Kyrie has her heart.

With that conclusion in mind, it was not as difficult as he imagined to softening his features a little in return. No, he wasn't smiling back, but maybe one day Kyrie's presence would help him deal better with his memories of Eva, and if that day came to be, he could smile back to the girl.

… To be continued…

End note: I will put at the end of the chapter a guide to understand the concept of the demonic omegaverse that I am creating, since there are several types of omegaverse on different fanfics. By doing this, I hope I can help you guys remember the relevant points for the plot of this fanfic and not to be confused with other fanfics' universes. As I reveal new information in future chapters, new points will be added!

Demons spawn only one demon per pregnancy. The twins were born in the same gestation and that was something atypical, but it was only possible because their mother was human.

Demons are either omegas or alphas, and this definition does not depend on the demon's gender (female, male or intersex). Regardless of their gender, omegas can become pregnant.

Alphas fight with each other for territories' domination and to court omegas. The omega's heat affects the alpha as well, causing these alphas to become especially energetic when they are close to omegas in heat, to protect them and supply them with energy.

Omegas, during their heat, lose a lot of energy and need physical contact from an alpha so that the two can balance their energy levels. The exchange of energies' speed are intensified with the carnal contact, but the corporal approach is enough for this exchange to slowly happen.

Omegas that cannot obtain the energy of others during their heat dies.

As a consequence of this energy's need for survival, omegas are able to charm humans so that they can obtain energy in the absence of alphas to supply this need. Such power apply only against humans, which created the legend of succubus and incubus in the human world. (Observation: that means Vergil was able to charm Dante in the cemetery scene because Dante is a hybrid, so hybrids are also susceptible to this power because they are part-human. He cannot enchant a pure demon, though).

Hybrids have dynamics slightly different from pure demons: they acquire their needs from the demonic nature after their first devil trigger. Dante, however, only started to feel the effects of his alpha side only after acquiring his sin devil trigger (at least that is what it seems up to that point in the fanfic). The reason for this and more details about the difference in puberty moments between the three hybrids will be clarified in future chapters.

In a demon pregnancy, the pregnant omega/human need to obtain energy by someone, usually his alpha mate, to generate a heathy cub. In case they don't get the energy, the omega/human will be weakened and the pregnancy may suffer some… complications.

Any doubts? Let me know!
