Prologue

About 2000 years ago Ymir Fritz gained the power to become a titan, but around 13 years later he died and his titan strength was divided into 9 which made his descendants use that power to tear down the ancient nation of Marley and conquer the entire continent.

But after 1800 years passed the Marley people began to rebel and managed to get 7 out of 9 titan. Karl Fritz then moved his people to the island of Paradise and erected a 50 meter high wall which contained thousands of Collosus Titan.

Karl Fritz then told the Marley people, "if the Marleys still want to fight then he will release thousands of Collosus Titans" since then the Marleys did not dare to colonize the Eldians on the island of Paradise.

Year 844

=========================

Currently in the Tybur family there is a figure of an 11-year-old boy playing with his 14-year-old sister. They are Willem Tybur and also Alicia Tybur (Willy's sister, I don't know her name so I named her: D).

A boy, wearing luxurious black clothes like a noble, he has short black hair to the top of his ears with blue eyes, he has a round head with straight eyebrows.

While the female, wearing a black noblewoman's clothing with blue eyes, she has long black hair on the braid tie, she has an oval head with curved eyebrows.

"Big Sister Alicia, when did Big Brother Willy go home?" asked the boy curiously. Alicia smiled at her younger brother, "Big Brother Willy is having a meeting with important people of Willem, so he is a bit late returning" she explained.

Willem then lowered his head, "I see," he said sadly. Alicia rubbed her head, "But I'm sure that Big Brother Willy will come home soon," she said with a smile. Willem looked enthusiastically at his oldest sister, "Really Sis !?" he asked.

Before Alicia opened her mouth, "I'm home, Willem," said the man's voice that made them turn around and saw a shoulder-length yellow-haired man with blue eyes who appeared to be 18 years old, had a muscular body and dressed in black nobleman clothes, he had a head shape oval with thin eyebrows.

Willem looked happily, "Big Brother Willy!" he shouted as he ran to the man and hugged his hips. Willy laughed happily, "Hello, my little brother, how was your day? How nice?" he asked.

Willem nodded his head enthusiastically, "Yes Big Brother, but it's even more fun with Big Bro," he said with a sad look. Willy smiled at him and rubbed his younger brother's head, "You know that I am the head of the family, so I can't have free time" he said.

Willem became sad to hear, "But can you try to be able to play with me, please?" asked him with a puppy gaze. Willy sighed with a smile on her face, "Good will I try to be able to spend my time playing with you, how?" he asked.

Willem nodded enthusiastically to hear, "Promise !?" he asked excitedly while showing his little finger. Willy nodded her head, "Promise," he said, holding his little finger.

Willem just grinned happily, "Then what if we play together, now?" Willy advised his younger brother. the reply was nodded, "Then you go out for a while, Big Bro wants to talk for a while with Big Sis," said Willy. Willem then nodded his head and walked out leaving the two of them.

Alice looked at her older brother, "What do you want to talk to me about, Brother?" she asked. Willy looked at his sister, "Alice, do you remember what we talked about a week ago?" he asked seriously.

Alice stared in surprise at him, "The conversation where I will inherit Titan WarHammer? Why is it, Big Brother?" she asked curiously. Willy took a deep breath, "Looks like you won't inherit it, but you will inherit the Titan WarHammee is Willem" he explained.

Alice's eyes began to widen at the explanation, "What !? Why would Willem have to inherit Titan WarHammer, Big Brother !?" she asked angrily. Willy sighed, "We wanted to make WarHammer Titan the last defense of the Marley nation, but Zekke suggested sending WarHammer too so that this mission would run successfully," he explained.

Alice stared in surprise at her older brother, "Then why should Willem inherit the Warhammer Titan instead of me?" she asked curiously. Before she finally realized looked at him understandingly, "Don't tell me ...!" she said with eyes that began to widen.

Willy nodded her head, "That's right, because Willem has been chosen to be a candidate and will take part in training along with the others," he explained. Alice stared angrily, * Plack * slapped Willy.

Willy held his cheek slapped by her and looked into the angry eyes of his sister, "Are you crazy, Brother !? Why did you send Willem there !? He can die you know!" she said with an angry look.

"You know I don't want to do it, but this is for our family too! I'm afraid the offspring of Karl Fritz will wake up thousands of Collosul Titan hiding inside the wall! That's why I agree" he explained, shouting loudly.

Alice then covered her face with her hand, "Is there another way?" she asked. Willy shook his head, "There is no other way, Alice. We just need to accept it," he said with a sad look. Alice then looked at her brother while shedding tears, "But he is our younger brother, Brother," she explained clearly crying.

Willy then embraced his sister, "I know, that's why we have to give him support from today onwards," he explained, who responded with a nod from him. They didn't know that Willem was listening to their conversation behind the door.

Dinner

========================

Currently the Tybur family is having dinner while chatting with each other. While Willem only played his spoon which made Willy stare curiously, "What's wrong, Will? Why don't you eat your food, does the dish not taste good?" he asked.

Willem did not answer for a few moments before finally staring at him seriously, "Big Bro! I will accept it!" he said suddenly, which made them surprised to hear that. While Willy looked confused, "Accept what, Willem?" he asked.

"I accepted it to inherit Titan WarHammer!" he clearly made them shock. Alice then hit the table with both hands while rising from her seat, "Willem! Do you know what you're talking about !?" she shouted. Willem nodded his head, "I know that, Sis!" he said.

Willy looked at his younger brother for a while before finally he sighed with resignation, "If that's what you want, then I won't ban it," he said. Alice stared in shock at him, "Big Brother!" she shouted in a voice of disbelief.

Willy raised his hand which made her close her mouth, "I know you're worried about him, but right now we have no other choice," he said. He then looked at Willem seriously, "Are you sure of your decision? You won't be able to return to normal if you accept it," he said.

Willem lowered his head while clenching his fist, "I know that, Big Brother" then he raised his head and looked confidently, "but I did it to protect all of you!" he explained.

Willy smiled at him, "Okay then! From today onwards you are the Warrior of Marley, Willem Tybur!" he said loudly.
