"Iruma-chi no!"

"Ok. That's enough!" Sullivan exclaimed, bursting into the room and using his magic to freeze Iruma. He then moved them apart and put Clara in the middle, to then unfreeze his grandson. "Iruma-chan!" He exclaimed in his childish happy tone, to then enveloped him into a tight hug. "I am so glad you are fine now," he whispered into his ear, his tone now serious but still as warm as the one before. "You had us all worried," he returned to his usual childish self, spinning around the room in cheerful laughter.

"Iruma-chi!" Clara exclaimed happily, jumping on her best friend and giving him a bear hug.

Alice would have joined then and there but he was still breathless about the whole almost mating. His face was red and he was panting, looking at Iruma with an almost glazed expression. For some reason, Iruma thought he looked delicious like that. The Demi Demon blushed at the fleeting thought, looking away from those passionate and lovely pink eyes.

"I need to tell everyone that you are awake!" Sullivan exclaimed happily, still spinning all around the room.

"Everyone? W-what do you mean Ojii-san? What happened?" Iruma asked, his memories before passing out were blurry.

"Iruma-sama, do you remember what happened after you defeated the demonic best?" Alice asked him, finally snapping out of his trance.

He crawled towards Iruma, his Omega wanting to be closer to his Alpha after everything that happened. He finally had him back and needed to be scented, to have the reassurance that his Alpha was there safe and sound, and wanted him. Iruma, on the other hand, could not take his eyes off the crawling form of his best friend.

He looks so good like that... on his knees for me... WHAT THE HELL I AM THINKING?! Iruma exclaimed in his head, blushing like a tomato. Az-kun is my best friend. Yes, he has always been very pretty to me and I had always wanted him close but he deserves better than to be thought of like that. Not to mention he would never want me once he finds out that I am human.

"Master you are finally awake!" Arikured exclaimed, showing itself to everyone in the room. "Great news Master! The Demi Demon transition was a success and you even rose a rank, you are a Daleth now- like Alice-sama." Arikured used the stored magic inside him to levitate Iruma's insignia to show him his new rank. Iruma took the cold metal and stared at it in shock. He was truly a Daleth now. "Thanks to your new rank everyone can see me now. There's no need to go sneaking around anymore! You don't even have to hide the fact that you used to be a human anymore... well, you don't have to hide it from Alice-sama, Clara, and Eggy-sensei. Or those who already knew."

"Ah... everyone knows," Iruma gasped in shock, looking at his best friends in worry. "No one cares?" He asked fearful, not sure if he wanted the reply.

"Iruma-sama is Iruma-sama, it doesn't matter if you are a demon, human, or Demi Demon," Alice told his beloved.

Alice then hugged him from behind and nuzzling his face into the crook of his neck- right beside the scent glands. Iruma was blushing like a mad man... but he quite enjoy the peacefulness the hug gave him, so he did not move. Not to mention he loved the scent that came from the pink-haired man.

"Ali-chi is right! Iruma-chi will always be Iruma-chi." Clara exclaimed excitedly.

She was so happy, everyone was so happy. Iruma was awake and not only did the transition suit his body, but he has also regained his kind and gentle nature. He was still the same Iruma as he was when he was a human. Nothing changed.

"Ali-chi? How much did I miss?" Iruma asked, chuckling at how Clara it was.

"You've been out for three days Master," Ali-san told him.

"Three days?!" Iruma exclaimed shocked.

"Yes, but don't worry. Nothing much happened, Iruma-sama." Alice whispered into his ear, sending shivers down the Demi Demon's spine. "We stayed by your side, waiting for you to wake up."

B-by m-my side? Did Az-kun sleep with me?! Iruma stuttered in his head, he was about to pass out once again from all the blushing.

"Iruma-sama/Iruma," suddenly Opera and Kalego-sensei burst into the room, both looking relieved at seeing Iruma awake- though they returned to their usual expressions rapidly.

"Opera! Kalego-sensei!" Iruma looked at them surprised, wondering what was wrong. "What really happened while I was out? It can't be that I was simply sleeping. Everyone is too worried for that."

Everyone evaded the eyes of the Demi Demon, looking away in shame.

"I can answer that for you," Henri said, entering the room with his daughter by his side. "First, I am glad you are ok Iruma."

"Thank you, sir." The previous human replied, accepting the worried hug of Ameri- who later took her place on the bed, beside Clara.

"About what happened to you, what's the last thing you remember?" The Head of the Demon Police Department asked.

"I remember coming home from the park and falling into my knees, there was a lot of pain," Iruma answered, trembling a bit at the painful memory. Alice could only hug him even tighter. "Then I heard Ali-san's voice telling me that the magic from the demonic beast was too much for the ring to handle and what was left was going to my body. But as a human that cannot possess magic, I was gonna die, but if I turned into a Demi Demon I could be saved... then everything went black." He finally looked up from his hands and asked the fox demon. "How did I survive?"

"Well, we are still not sure about that," Henri replied. "We believe that your body had gotten used to the demonic aura and magic by spending almost a year in the Netherworld and using the ring of gluttony. We think that it prepared your body for the transition, but as you are the first person to have ever survived the process we cannot say for sure. You also had to die for a few seconds to complete the process."

"Which is why Kalego-sensei knows about me being once human, because our familiar bond broke," Iruma commented out loud looking at his teacher with a melancholic feeling. "This is serious, isn't it? Me being a transformed Demi Demon." Iruma inquired, he was not oblivious of the grim expressions everyone was spouting.

"Look Iruma, there had only been one Demi Demon in history: the previous Demon King." Henri began telling the boy. "He was a student at Babirus, brilliant, charismatic, and powerful- with a blood skill that surpassed all others. He was the epitome of being a Demon. The consul wanted him on the throne, but he refused. He had no desire for it, so after graduation, he went into hiding. But that did not stop the consul from wanting a Demi Demon on the throne. They kidnapped many humans, trying to create a Demi Demon naturally but as more and more babies did not survive, they started experimenting trying to transform demons and humans alike into Demi Demons. It was pure chaos, it was a time of madness and terror. It was called the Era of the Mad Doctors." Henri sighed when Iruma looked at him with an expression of pure horror, the boy was finally realizing how serious the situation was. "It only stopped when the Demon King finally stopped hiding and killed the whole consul, all eleven seats except for the Asmodeus and Azazel seats of back then. They were the only ones who did not agree with what the rest of the consul wanted and tried to put an end to all the madness. We do not believe that the new consul would go nuts as the previous ones did, but there's still a chance. Not to mention that there are still a few supporters of the previous consul lurking in the shadows, and we do not want them to regain hope whatsoever. So, we will tell them that you have always been a Demi Demon but were born from a female human so Lord Sullivan had to get you from the human world."

"Does that mean that the consul will want me to be the next Demon King?" Iruma asked, a bit afraid of the prospect of being king of any kind.

"Yes, most likely," Henri answered the boy when no one else had the heart to tell him the truth. "Not only are you the second Demi Demon in history, but you are also the heir to Lord Sullivan- one of the three beasts. Not to mention that you are a good friend of my daughter, having the future and actual seat of the Azazel family as your ally, and an Asmodeus as your mate. An excellent choice as a spouse and Queen. It makes you the best candidate. But worry not the consul will not know about you until after your graduation and even then if you do not want the throne you will have our support."

"Mate?" Iruma was finally done, he could deal with becoming a Demi Demon, with possibly being the next Demon King... but what the heck was this about Az-kun being his mate?!

"You were not told about that yet?" Henri looked at the boy shocked.

"He only just woke up!" Alice defended his mate, glaring at the fox and hugging the Alpha closer- afraid of the other running away.

"But he has been in the Netherworld for almost a year! He should know about those things!" Henri replied, glaring at Sullivan. "You really told him nothing about this world."

"I simply wanted him to be a carefree boy, I did not want to spook him with how different our worlds truly are," Sullivan confessed, sighing. He then looked at his grandson and began to speak. "The genders male and female are known as someone's primary sex. When one is around 5 to 10 years old, throughout various medical check-ups, the secondary sex is determined. The classifications are Alpha, Beta, or Omega. Due to the difference in their characterization, their rank and status in society used to be determined after their distinction. Nowadays as long as you are strong it does not matter which secondary gender you are. One clear example is Asmodeus-kun, he is an Omega but is well respected by everyone because of his power and talent."

"What am I then?" Iruma asked confused.

"When you were human you did not have a secondary gender, but now that you are a Demi Demon you do. You are an Alpha," his grandfather answered him. "Alpha possesses excellent intelligence and perfect physical abilities, they are characterized for being very charismatic. They make up ten percent of the Netherworld's population. Many alphas assume leadership roles, government positions or heads of successful businesses." Sullivan explained, confusing Iruma even more. Why would he be an Alpha? That gender suited Az-kun more than him. "They go through a runt once a year, which is the only time of the year they can knot their partners- but it only happens if the Alpha has an intent of mating with a mentioned partner. If not they simply go through the rut with an extreme need of sexual release and not to impregnate their partner. However, sometimes when being exposed to Omega pheromones- if the Alpha does not have great control of their impulses- they end up mating with the Omega, even if they don't know each other."

"Knot? As in dog's knot?" Iruma squeaked, not believing his ears.

"Yes, just like that." Surprisingly it was Kalego-sensei the one who answered. "From what the ring of gluttony told us you don't have to worry about losing control during a rut or by Omega hormones, your human side protects you from that."

"That's good to know," muttered Iruma, overwhelmed by all the information.

"Can I continue?" Sullivan asked his grandson, realizing that they were overwhelming him with all of this new information. He continued his explanation once Iruma nodded his head. "Beta is of average ability and physique. They make up about the majority of the Netherworld population, around eighty-five percent. They are the common people with various social statuses. While they might be affected by an Omega's pheromone, that only happens when the Omega is in heat, and even then a Beta can control themselves. The principal reasons why in heat hospitals the majority of the staff are Betas."

"Heat Hospitals?" Iruma inquired, curiously.

"Heat Hospitals, are institutions where Omegas can go to transit their heat when they have no heat partner and their doctor recommended off suppressants. Suppressing an Omega heat for too long is not recommended, because it brings consequences to an Omega's health." Alice was the one to explain this time around. "My mother as the Head of Lust is in charge of them."

"Then there are Omegas. Pregnancy is possible for both males and females. They are known for being the most fertile and nutrient secondary sex, and for birthing the strongest and healthiest pups. They form five percent of the world population. The majority are females, with a small percentage of 1% being male. Though it is not rare for a male Asmodeus to be an Omega, as they come from a long line of succumbs- which are widely known for having Omegas in their lines." Sullivan continued his explanation. "Because of the biological implications of their heats they were usually regulated to the lowest of social classes, as many Omegas did not receive or complete a proper education."

"However, that's different now," Ameri jumped in. "Now whoever proves himself worthy will be respected, despite their secondary gender. Those changes came around the time of the Demon King, which is why many want another Demi Demon on the throne. They are known for bringing prosperity during their ruling, their human side giving them a new perspective of many issues."

"What are heats?" Iruma asked, not noticing the blushing faces of the two Omegas in the room.

"Heats are like ruts but instead of wanting to fuck, you want to be fucked," explained Opera. "They happen once every 4 to 6 months for around one week. Due to a constant heavy emission of pheromones during the seven days, Omegas are unable to go about their daily lives. They are their most fertile during this period and is the only time that an Alpha can knot outside their rut- this is how strong an Omega's pheromones in heat is. An Omega can suppress their heat and daily pheromones release, by consuming suppressants once per day, which also acts as birth control pills. However, it is recommended to only suppressing for a year. If they do it for longer, an Omega's health could be in danger."

"Won't people question why I am an Alpha out of the sudden?" Iruma asked no one in particular.

"That won't be a problem, because when I made you smell like a demon I made sure it was an Alpha demon," Sullivan answered him.

"What does that mean?" The Demi Demon inquired, confused once again.

"You can differentiate Alphas, Omegas, and Betas by their scent," Henri continued explaining. "Alphas possess this strong scent, woody like. While Omegas smell sweeter than anything you've scented before. Betas scent is faint and normal."

"So, that's why Az-kun smelled so good," Iruma commented, oblivious of how red he made Alice. "Kalego-sensei smells sweet as well, does that mean he is an Omega."

"He is," Opera replied, "Why don't you try to guess what secondary gender the rest of us are?"

"Opera and Henri-san are Alphas." Iruma guessed, getting nods from both fox demons. "Ameri-san and Clara are Betas," The girls nodded at him, smiling at him. "Sorry, Ojii-san I don't know what you are," he apologized.

"Don't worry about it," he told his grandson with a kind smile. "I am a Beta, but because my magic is too powerful my scent comes out strongly and confuses many people. You did well, for your first time." He praised Iruma, who smiled at his grandson. "However, Asmodeus-kun does not smell good only because he is an Omega?" He told Iruma. "He smells that good because he is your mate."
