For several years, the descendants of Primordial beings, also known as Tyrants roamed our Earth. Their only aim was to claim the planet for themselves. These Tyrants existed even before Dinosaurs existed. Back then, they were handful in number, and peaceful in nature. However, when Homo Sapiens, in other words, Humans arrived and started damaging Earth, these beings decided to evolve. They expanded in numbers and divided in several Tyrants, with a Tyrant being their King, also known as Father. A Father is a possessor of the Tyrants' life source. If any other being, other than a Tyrant kills the Father. That would bring in the end of whole Tyrant population. Tyrants started creating havoc on Humans which they called as 'Tyranny'. However, there exists few humans, who can bond with a Tyrant so well, they could convert into one at will. They were called as, 'Tyrant Shifters'.

For several years, the heads of 'Descendants of Kaos' have kept on descending the bloodline of Father. This dynasty is so wide, that they may have many unknown relatives. Who knows the person next to you is a descendant of Kaos? With time, this dynasty has taught Tyrants to transform into other animals as well. They became so professional in this, it is like they use the DNA and neurons to transform into an animal. Due to this, they may disguise as Humans so well, you will never understand that there's an impostor among us. They are termed as "Impostors".

"... I guess this information is enough to understand that what you think is very-very-very dangerous." a short, 10 year old, blonde boy, with fair skin and blue eyes told.

"I know. But these Tyrants are the reason I, my sister and you are orphans, Aaron." A tall, 10 year old, brown skinned boy with brown eyes told to the blonde boy. "She even was about to die, only if, that Soldier didn't saved her." he said with almost crying expression. "Look Aaron, she's still traumatised, she hasn't even spoke a word."

"Uh that's not the thing Erik." a little tall, 12 year old brunette girl, with black eyes said getting up from ground, to that brown haired boy. "I am fine Erik. Its just this happened too quickly I couldn't absorb quickly."

"See Erik! Even Madelyn is fine. Taking an impulsive decision like this may get you killed. You're just a 10 year old kid. Don't think so impulsively." Aaron said.

"I don't care. I'm joining Operations Squad and will lend my strength in fighting these Tyrants." Erik said in a frustrated tone..

The boy, Erik and Madelyn, they are siblings, with Madelyn being the elder sister. Aaron is a boy who lived in neighbourhood. These three were closest friends. They live in a remote village situated in the foot of a hill near Duadella city. Their family were farmers who traded with the city markets. Since we are talking about childhood, Madelyn didn't have a very good childhood, compared to her brother Erik. She was the girl who was given harsh tasks by her father since she was just a 5 year old. However, her mother cared for her, she cared more of Erik, than Madelyn. It was clearly understandable if anyone saw. The only one who loved her was none other than Erik. He loved his sister so much, he often had fights with his parents for her. Erik and Madelyn met Aaron when one day Madelyn was tasked to look after her brother, Erik, when he was going out to play. Since then, they are closest friends.

The village, the city, they were all situated in the coastal part of the continent. This place was famous for Tyrant sightings, however, since 15 years there hasn't been a single sighting in the village area. However, there were few sightings near the outskirts of Duadella city, which were taken care by Operation Squad, often called as Ops. Operation Squad is the squad who specialise in handling Tyrant cases.

Just before the conversation that occurred between Erik, Aaron and Madelyn, a Tyrant attack occurred. These kids were out to play as it was there play time. When they were on their route to return, they heard alert sirens, and suddenly, a giant Tyrant appeared out of nowhere. Probably an Impostor who came in this village.

It was a 15m Tyrant that appeared out of nowhere. The kids were panicked and so they ran towards their home to go back to their parents. However, when they returned, they saw their houses crushed. Erik ran towards the debris, while Madelyn fell on the ground with tears coming out of her eyes. Aaron ran to his house with tears blinding him. They couldn't remove much since they were kids. Then a man who resided in their neighbourhood came and told them to live with them. The kids weren't willing to move but they reluctantly agreed after he explained the situation to them. Erik and Aaron were moving ahead, following the man, while Madelyn was behind. She was so lost she didn't recognise the distance between Erik and Aaron, and her was increasing. Suddenly everyone heard a bell ringing.

"Ah! The Ops arrived." the man said, and the kids looked towards the Tyrant's direction. Few people in black dress were fighting it. Flying from here, to there. That view caught Erik's eyes and he stood watching them.

They defeated it, but no one realised it was falling towards Madelyn's direction. The time she realised, it was late. The corpse was falling over her. She was too scared and panicked to move. "Madeelllyyynnnnn!" was what Erik cried.

Suddenly a dark figure appeared out of nowhere, which came flying towards Madelyn. It held her, "Hold me tighter or you may fall." he whispered in her ears, and flew again, taking Madelyn out of the zone of the falling corpse. Madelyn was afraid, yet she held him tighter.

"We're out. Are you fine?" the man asked. Then Madelyn let go. She noticed the man was in a different suit than a usual Ops soldier. He wore a cowl instead of mask. He was speaking in a deeper voice than an average man. Madelyn was still afraid, shaking, and nervous. The man noticed that. He gently rubbed her head. "Don't worry. We are out of the danger. You may relax now."

Hearing these comfort words, she calmed down. Then the man held his ear portion of the cowl, probably he was listening someone talking from there.

"Alright. I'm coming. (To Madelyn) Take Care kid." he said and flew away.

Madelyn was still looking in his direction. Her eyes were locked on him until he disappeared. "Madelyn!" Erik's voice came from behind. She turned around and saw Erik and Aaron running and coming towards her along with the man with whom they were leaving this place. "Madelyn! Are you fine? Are you okay? You aren't wounded anywhere are you?" he asked. "Let her get normal first Erik." Aaron said trying to calm Erik.

"Here. Have some water." the man offered. "Thank you." Madelyn said while taking the bottle and drinking some amount of water. Then, both Erik and Madelyn were looking towards Operation Squad Soldiers, clearing up some mess. "Understood." Erik begun. "I will become an Operation Squad Soldier as well."

"What?" Aaron asked in shock.

"Yes. I will become an Operation Squad Soldier and fight what you call the Tyrants." Erik said with a determined tone.

"Are you serious? You know what the Tyrants are?" Aaron asked.

"That's why I have you." Erik replied with a wink.

"Fine." Aaron replied with a sigh.

"So a Tyrant is a..." Aaron begun.

Present time

Aaron sighed. "You have great knowledge and memory for a 10 year old Aaron, do you know that?" the man said.

"Thanks." Aaron replied with a blushing smile.

"Well they need new soldiers as well." the man replied thinking something.

"Really! How do you know?" Erik asked with starry eyes.

"Uh my brother was an Ops soldier as well. He died in the precious expedition. But he told me to save as many survivors possible whenever a Tyrant arrives. That's why I saved you all." the man replied.

"I see." Erik replied. "We are sorry for such impudence. (To Erik) Where are you manners Erik? (To the man again) And we are sorry for your brother, sir" Madelyn said getting up from the ground.

"Oh its fine. By the way, if you're really determined to become an Ops soldier. You need to join an institution since you all are younger. You will have to be at least 18 year old to join to become a soldier. Well luckily I know a place." the man said.

"Really! Thank You!" Erik said jumping in joy.

"If you're going, I'm coming as well." Madelyn said with a straight face.

"I too don't have anywhere to go. I shall join as well." Aaron said with a hesitant tone.

"Hey you all! no need to join me. I am going alone." Erik said.

"If you are going, we are coming. That's final." Madelyn said with an expressionless face.

Erik sighed. The man started laughing. "Alright kids. Come follow me."
