Title: The Tyrant of my Heart

The Apocalypse of Human Extinction

~~Past~~

In the beginning, when humanity was at peace, it was normal for a man and a woman to have a family. There's was nothing unatural of the situation that you could see both genders coexist with each other. It was always like this for millions of years, that is until 'it' happened. A sudden unknown disease was discovered in a young woman. It seemed to have regular symptoms that of the common cold, but suddenly the coughing that came led to spurting out blood. Not to mention that the cells and tissues of the brain began to deteriorate until the disease reached the heart and the young woman died. The disease was scary enough, but many thought it to be a rare case and did not expect to see it again. That is, until, suddenly the nations went into havoc informing the sudden death of millions of women.

Men having strange immunity to the disease went into action trying to find a cure. As many more deaths were reported, the men were growing anxious going as far as auctioning by force the remaining healthy women and enslaving them for their own, but even then they could not save them. And after 2 decades the last surviving female gave her last breath symbolizing the full extinction of the female race. The men were anxious. How could they possibly continue to live without being able to reproduce. After a few years, a group of elites created a plan they called "Rebirth of Humanity". In order to keep their population from going extinct, the remaining male population was seperated into two groups;(1) the Shimas and the Heras.

The Shimas were the males that would undergo the rest of their lives to being 'females' in the relationship and were given a new drug called the "x" drug in order to develop female desirable characteristic and birthing abilities. The Heras were those males considered the strongest and most dominating in the relationship. Just like when women were living, the Heras took the Shimas' right to make decisions. The Heras were the ones in control, and the Shimas were forced into obedience. The Heras were wedded to Shimas and mated baring children successfully.

It was then that a monarchy was established and a group of officials from every region worked in the hospitals deciding which child would be a Hera, and which child needed the x-drug to be a Shima. And to this day that has been their system of balance.

~~xXXx~~

The place was an orphanage. But ever since the beginning of the system for reconstruction, it was considered as more as an auction. Since their necessity was rebirth of humanity, they couldn't leave behind any orphans or else their goal would never be accomplished. Every time an orphan reached 12 he was put in auction where wealthy noble families bought them. One of thoese 12 year old orphans in particular was named Eren Jaeger and his parents were killed when he was just 5 years old.

Said boy was snoring lightly on the hard mattress that was his small bed. WIth ragedy brown covers ripped completely and soaked as a result of the storm and leaks from the ceiling. "Eren!" a voice boomed angrily. The boy jumped out of bed terrified to no extent. His turquiose eyes widened as he tried to straighten his long brown locks that reached his back. Eren in fact was a Shima and a very beautiful one for his age. Back to the, booming voice, it belonged to the head master of the orphanage who was tapping his foot impatiently with hands on his hips.

"Headmaster Sarah...pleasant seeing you here", Eren chuckled nervously. "Trying to sleep in during auctioning are we?" Sarah huffed angrily. Eren sighed irritated by their insistence to be adopted. "Eren, you can't go on like this forever. You are a young and beautiful Shima that has potential to be given a family at the blink of an eye. Eren...you could have a comfortable life with a loving family. Not to mention you staying takes away potential money to receive another abandoned child or funds to feed more of you", the head master sighed cupping Eren's cheek.

Eren looked down ashamed. Was he really being a cause of other kids having less? "Are you serious?" Eren asked concerned. Sarah sat on his bed and after a few moments nodded. "Unfortunately, yes. Eren, do you now understand why we auction children every weekend?", Sarah explained. Eren looked down thoughtfully and nodded. "Now Eren, a whole lot of families of noble decent have gathered to adopt a Shima. You can have a much better life than now. Will you try Eren?" Sarah asked him. Eren looked at him and nodded.

Sarah hugged him tightly. Eren was his favorite, and he wanted him to have a great family which is why he had let his other stunts to avoid getting adopted slide, but nobles had money and a life to give a boy who saw his mother murdered. The headmaster bathed Eren and curled his hair and made him wear a dress with the top in a heart shape and overflowed from the waist. Eren stared at his reflection. He looked really clean unlike his usual appearance. He was led onto the stage draped with bright red curtains and blinding lights. As soon as he stepped on the polished floor murmurs and gasps were heard.

It wasn't long before the auction began. The first was a thin shima with red curly hair that was sold off in the end at $1000. One after the other, they were sold off and finally it was Eren's turn. "Now we have another splendid beauty. A shima of such fine eyes and their teal color is amazing. But unfortunately this child was cruelly abandoned by his mother", the announcer shouted and Eren swallowed hard trying to avoid from yelling out that his mother did not abandon him. "We shall start the auction for Eren Jaeger!" the announcer chirped. "$1000", someone yelled immediately.

Eren was shocked at the price, but the man looked like he was only seeking him for pleasure. "$2000", a fat shima yelled far back. "$5,000!", "$7,000!" Many prices were thrown back and fourth leaving Eren shocked. 'So much money! I have to be adopted...for the kids' Eren thought to himself. "Okay, we're at $60,000. Does anyone have another offer. Going once, going twice and-", the announcer was about to close off the auction until someone interrupted. "3 million!" Someone yelled leaving people gasping in incredulity. The Hera stepped forward in clothes too elegant for the status of an auction like this. A shima with a beautiful long red dress and black locks draped to his arm. "T-The Ackermans!" They all said giving a bow of respect as should be given to the nobles working for the king. "We'd like to take our child now", the Shima smiled. The announcer nodded still mouth agape as headmaster Sarah led the two nobles along with Eren to his office.

"Mr. and Mrs. Ackerman, such gracious honor to adopt our Eren", Sarah said still shocked as Eren stood fidgeting with his dress beside him. "Well that child is certainly special. The beaury he possesses is remarkable, but the innocence and determination he radiated made him worth it", Mr. Ackerman explained. Sarah nodded taking out the paperwork for the adoption. "So what will be Eren's new name?" Sarah asked making Eren look at her with panic, not going unnoticed by the couple. "Nonesense! Eren Jaeger is fine, but we only ask that Ackerman be added", Mr. Ackerman laughed as the papers were finalized. Eren was led to the car which was opened by the chauffeur.

"Get on, my lady", he said respectfully. Eren turned to run back and hugged Sarah tightly. He sobbed, tears leaking down his cheeks. "Thank you for everything, Sarah! I'm going to miss you", Eren cried. Sarah let tears escape his own eyes as he leaned down to kiss Eren's forehead. "Sweet child, you have been blessed with a chance of a real life. Take care, Eren". Eren nodded as his new parents took him into a hug. They were surprisingly warm and genuine. They rode off at first in silence. "Eren, my child, from now on I'll be your mother. My name is Yuki Ackerman", Yuki gave him a sweet smile. "And I'll be your new father, Damian Ackerman", the Hera chuckled.

"Thank you...for taking me in", Eren muttered. "No need. You are our child now. You'll meet your brother soon", Yuki clapped. Eren looked out the window. The kingdom they lived in was separated by three walls to ensure that another disease was blocked from infecting nobles. Eren still couldn't believe he was now a noble of the highest class. The Ackerman family are the most powerful family right after the royal family. The car reached to a stop and Eren couldn't help, but gawk at the enormous estate that was now his home. The door was opened for him as he entered the house to be greeted by a handsome Hera no older than Erenwith black short hair and dark gray eyes. "Mika (male!Mikasa), come!" Yuki called excitedly. Mika walked forward looking at Eren with an intense look. "Meet your new sister, Eren", Damian grinned.

Eren gulped a bit intimidated until the boy smiled. "Mika Ackerman, I hope we'll get along Eren", he said kissing the back of his hand. Eren smiled back relieved. "Yeah", he agreed.
