What you thought would be a marvelous morning quickly turned into one of your worst nightmares. It first started with the loud commotion coming from below, before you heard people screaming in the streets. Your eyes shut open abruptly, wandering to a window to see that a fire has started outside. You panicked, jumping from your bed and pulling on a night robe that you fastened as quick as possible. You made your way downstairs in a record time of five seconds, heading to your living room.

You let out a scream of disbelief when you saw that one of the four walls was teared down, giving a not-so-nice view on your street where your neighbors were practically running in circles as they yelled incoherent things. Something about a huge beast, and your mind began to wander and turn around thoughts that filled you with dread when you realized that Dino was nowhere to be found. Inside your house that is, because you could clearly see him on the other side of the street, destroying a whole house with his tail.

"Dino!"

The wyvern was beyond furious for an unknown reason, lashing out at everything around him. The once white feathers were now completely black, shifting sometimes to their original color for a brief moment. His eyes were a feral red and orange, lightnings reflecting behind them. You tried to get as close as possible to Dino, but the state he was in wasn't too reassuring. Your face paled when you saw a mother and her child trying to run away from the Thunderous Wyvern, but the beast had them in his sight.

Dino released a ferocious roar before charging at them, feathers standing on edge. The woman screamed in fear, embracing her son much more tightly as she realized that she couldn't outrun the wyvern. She braced herself for the next attack, but you already took action by standing in front of them with your arms outstretched. Dino completely went still, stopping just a feet away from you.

"Dino! What are you doing?!" you shouted angrily. "What's wrong with you?!!"

"SKYAWK!!!!!" was his response, eyes glowing.

The mother took this moment of distraction to run away while the attention of the Thunderous Wyvern was focused on you. You also had time to take in your surroundings. The whole town was in disarray: in only a short amount of time, lots of houses were destroyed and multiple fires started. Dark marks were littering the street and the grass, as if a thunderstorm passed there not too long ago. That's probably what Dino brought, though.

"Dino..." you started, much calmer. "Does it hurt somewhere?..."

The wyvern took one step forward, and then suddenly swung his tail to knock you off of your feet. You groaned in pain as your head collided with the concrete, your sight becoming blurry as your pet hovered your form. Dino gritted his teeth at you, snarling and growling like a mad dog. He opened his beak, perhaps to rip your face off when he let out a shriek. You saw a syringe poking out from the middle of his back as the wyvern fell forward, out like a light.

You blinked, gazing in mild horror as you thought that someone killed him when Maryanne stepped in your line of sight. The blonde was clad in a white lab coat, hair pulled into a long ponytail.

"Chef (y/n)" she spoke, nodding at you.

"W-What did you do to him?!" you demanded, standing up and facing the woman.

"A sedative, simple as that" she answered as she showed you the bottle in question. "You should thank me for saving your life. LMO-TE-391 would have killed you if I didn't intervene"

"His name is Dino-!" you scowled, and Maryanne Angevin gave you a look that said long.

"That creature isn't your 'Dino'. It's currently going through another phase of our experiment. An evolution of sort that all our previous LMO-TE went through. Except, it's the only one who made it this far..."

"W-What exactly is evolving right now?"

"The beast's Gourmet Cells. Tons and tons of DNA codes written in its veins that are all flooding at the same time, with an incredible hunting history that made the Thunderous Wyvern tops the two species of Derous and Thunderbirds" the woman stated, almost in awe as she examined Dino. "And now it's all coming together...Which means MGA will now undertake the necessary steps to make sure it doesn't die on us-"

"Just wait a second!" you snapped, grabbing her wrist to stop her filthy hands from running all over your friend. "You're taking him away from me?! I can't let you do that!"

"Stop being selfish and take a look around you..." Maryanne gritted her teeth. "Chef (y/n), if we don't intervene, this whole town will get demolished in a matter of seconds! You're taking unnecessary risks just because you hold affection for this thing!"

The two of you glared at each other intensely. While you hated the way she was treating Dino, she was also right. There's so much you don't know about the wyvern, and even IGO couldn't figure out completely the Thunderous Wyvern with the tests they ran. Plus, there was the modified cells in his body that only MGA knew how to deal with. You released Maryanne's wrist, sighing heavily as you let yourself drop down next to the sleeping form of Dino.

"...I want to understand, but I also want to keep him" you said sadly.

"MGA will take care of the rest, but I cannot promise you that...Dino will ever come back with you. That you want it or not, the beast is part to an experiment to ameliorate ingredients. This modified genetic is beyond your comprehension" replied Maryanne. "So leave the wyvern to me and my team......I...I will do my best to take care of him"

Your eyes filled with tears as you gazed at Dino, brushing your hand into his soft feathers. You only wanted the best for him.

"Thank you for letting me stay here for the time being..." you grabbed the tissue Coco handed over to you, snuffing in it.

Maryanne and a team of scientists from Modified Genetic Association brought Dino with them while the woman gave you a special number so you could keep up with them and being updated each time there's a change in the wyvern's behavior. Unfortunately, since your house has suffered a bit of damages from the Thunderous Wyvern's tantrum, you had to live elsewhere until the reparations.

"I don't understand...It seems like it happened in one night this change of attitude..." you groaned, bringing a hand over your forehead. "Dino had this kind of moments, but...never that violent"

"Well, we can only hope for the best from MGA, even if I don't trust them fully" spoke Coco, taking a seat next to you.

"Is he going to be fine?" you sniffed, tilting your head to lay it on your partner's shoulder. "I don't want him to be left all alone in some kind of cold cell, or worst..."

"I'm sure of it" the Heavenly King comforted you with a smile. "I don't see your future without him at your side"

"You always know what to say to cheer me up..." you couldn't help but smile too. "And what about you?"

"There's no need for me to look into it to know the answer"

You hummed in appreciation as Coco leaned his head to kiss and bite your neck, laying you down on the couch. You grew flustered when his hands played with the hem of your shirt, before wandering lower to your thighs to spread them. He took place in-between, his kisses becoming much forceful and his bites hard. His pelvis pressed against yours, eliciting a gasp from you and a grunt from his part. You were unfortunately interrupted by a phone call that vibrated in your back pocket of your pants. One that Maryanne gave to you after taking Dino, with her personal number.

The fortune teller didn't hesitate to show his displeasure as you sit up and took the call, taking his leave to change his mind.

"Chef (y/n)? You might want to visit us as soon as possible" the voice of Miss Angevin echoed from the other line.

Dino's health has changed drastically ever since his arrival at MGA, one that the scientists there couldn't explain. While his sudden moments of outbursts have decreased, Maryanne stated how the wyvern felt lonely without you by his side. To say that he was confused and sad would be an understatement. The Thunderous Wyvern didn't trust any employee there or scientist, to the point he would try to bite their heads off if they approached too close to his liking. A young woman in her twenties nearly lost a hand when Dino attacked her when she trespassed in his territory in his small terrarium.

MGA's Wul Branch wasn't that big of building, and didn't attract really the attention with its architecture. It seems like any normal facilities from far, but once you have a closer look, you could see how different it was for the inside. It reminded you a bit of the IGO lab at the Biotope 1. Maryanne was waiting for you outside the laboratory, her hands clasped behind her straightened back, always with the same serious look on her face. You exited the private limousine she rented, your eyes narrowed at the establishment. Here, there was no harmony, so much you could clearly imagine Sunny yelling his catchphrase at the ugliness of the environment.

Maryanne immediately led you inside, following closely after her as she made you visit the place. Or at least, the ones you were allowed in, which wasn't pretty much in the first place. Maybe the lobby and only the long corridor that led to Dino's terrarium.

"Isolated in the jungle, few wild beasts decide to venture here if they feel courageous enough. However, they eventually end up in either our food storage or part of an experiment..." the blonde told, sounding as uncaring as her words. "The lab possesses high security levels and are always verified each hour to assure their functionalities"

"Will we find other wild beasts here? How many terrarium do you exactly have?" you questioned.

"Wul Branch has over 100 terrariums, half of them containing various experiments. Our main branch counts 10 000" she answered with a shrug, and you gaped at her back.

"10 000?! How is that even possible?!"

"It is by being situated underground...and you can only access it by taking a subway that little knows where they connect to"

"But I suppose that you do?" you arched an eyebrow, glaring at her accusingly.

"I do" Maryanne smiled, cold and harsh.

Two sets of doors opened, and you entered a cold room with a single and huge glass. Behind was supposed to be some kind of jungle serenity with lots of plants and bushes. Instead of a terrarium, you thought it looked like more of a cage. You walked closer to it, and blinked when you saw a blurred figure rustle behind the foliage. Miss Angevin pressed some buttons in the background and the glass slit open in half to let you enter the terrarium. Immediately, you were tackled down by an enormous body and a long tongue licking your cheeks eagerly.

"O-Okay, Dino!" you giggled. "Down boy, down!"

Maryanne observed the interaction between you and the Thunderous Wyvern. Dino looked beyond elated to see you after such a long time, his feathers glowing much more brightly than usual. There was no denying about the bond your shared with the wyvern, something that the best scientists couldn't explain properly. She carefully advanced toward you, flinching however when the beast turned to glare at her bitterly.

"The tests have all ended up successful for the moment. If it continues like that, there's a chance you can bring him back home once the experiment is done" the blonde said, brown eyes stopping on you.

"You heard that?! Once it's done, you're coming back home!" you beamed at Dino with your arms outstretched, his tail wagging happily.

"I-I said it was a possibility-..."

Maryanne deadpanned as you completely ignored her, too busy in dancing in circles with your Thunderous Wyvern. As if you were already celebrating his release before even the end results. Then, there was the sound of clapping that brought hers and your attention to the other end of the room to see another blonde woman with shorter hair standing there. She was wearing a white and elegant, business dress with a red scarf around her neck. On it was a pin of an emblem hanging from it, the shape reminding you of something. Maryanne's body stiffened when she realized who it was, gritting her teeth tightly:

"Clara..." she growled.

"What a tearful reunion..." the woman spoke with a drawl, ending her sarcastic clapping. "Mary, I thought you were supposed to warn me before bringing that thing here..."

"Mary?..." you echoed, gazing between the two blondes.

"Oh? Is that the woman who stole our experiment?" Clara blinked down at you, feigning shock and slight outrage. "How strange of you to invite her here..."

"I didn't steal anything" you spat, glaring darkly at Clara. "Dino has been with me since he was born"

"Dino? She named that thing?" the blonde scoffed, staring mockingly at Maryanne who looked more than agitated. "Anyway. Maybe I should introduce myself...My name is Clara Angevin, president of Modified Genetic Association"

"Angevin?! Then you are..."

"Indeed. I'm unfortunately related to this good for nothing over there. A huge weight in the family since the day she became part of this world, my sister Maryanne Angevin"

"Sorry, sister...We didn't get the same privileges when we were young. While everything was served to you on a silver platter, I had to work on my part" growled back Maryanne, the two siblings sharing a death glare.

"Always this excuse" Clara cooed, bringing her hands on her hips. "Keep telling yourself that. It's good to have dreams"

"What do you want? Usually you try to not waste your saliva on me"

The blue eyes of the blonde woman narrowed as she smirked at her sister, simply snapping her fingers. The doors opened, and men clad in soldier uniforms entered the room, heading straight to Dino. One man caught your arm and pushed you out of the way as they grabbed the wyvern who began to fight them. Maryanne watched helplessly as they manhandled the Thunderous Wyvern out of the terrarium while you screamed at them to stop:

"Maryanne! Do something!" you shouted at her. "Where are they bringing him?!"

"Clara, the experiment isn't done yet...You can't bring him now!" she finally shouted at her sister.

"Or what?" Clara arched an eyebrow with an unimpressed expression. "Your orders were to bring LMO-TE-391 to the headquarters after you found it. And did you do instead? You tried to undo the experiment by hiding here..."

"Undo...the experiment?" you blinked in shock, gazing in stupor at Maryanne.

"I know what you do to them...I know everything about your line of work" spat the blonde. "Using MGA to create living weapons for those barbaric groups in the poorer countries of the Human World. That Thunderous Wyvern...it isn't yours! That's why I tried to remove those Gourmet Cells that were slowly pushing him in this state. You will destroy civilizations if I let you-"

"My dear, dear sister..." Clara shook her head, stepping closer to Maryanne. "What we gain from it is much more important. Those countries always pay me a good amount of money, and we get to create things that are...amazingly destructive!"

"That persona of yours who wants to play God...Do you even realize the damages you're causing?! Just like that monster you released in Bilal!..."

At her words, you had a flashback of the strange bottle you found inside the cave, and the mysterious insignia that was drawn on it. Could it be that the Toxic Gilamesh was also part of an experiment?!

"Ah yes, experiment LMO-TG....The Toxic Gilamesh that we tried to fuse with miasma, but it ended up as a failure so we tossed it in the middle of a desert..." shrugged Clara, and you became ticked off at her carelessness.

"The Taj Desert! You nearly killed the people of the Bilal Kingdom!!" you yelled in outrage, struggling to get out of the guard's hold.

"Yes, and what about it? Their kingdom will eventually disappear one day by an enemy country who decides to side with us...Perhaps I will test them with the Thunderous Wyvern once I'm done with this beast" Clara winked at you. "I feel like it'll be my best experiment to this day!"

"You're mad...just like father..." Maryanne growled, eyeing darkly her older sister while she scoffed.

"Please, don't put me under the same spotlight as he did...I won't do the same mistakes" the blonde mused, eyes squinted. "Now, let's start, shall we?"

You were lifted over the soldier's shoulder while Maryanne was taken by another. It was the last thing you saw before your vision became dark, hearing Dino's panicked shrieks in the background.
