Shadow Being System

William and Sam entered the classroom, and an immediate hush fell over their classmates. All eyes turned to them, some with awe and others with disdain. The girls gazed at William as if he were a rare gem, their eyes sparkling with admiration. The boys, however, shot him looks of scorn, clearly annoyed by his mere presence.

Ignoring the stares, William and Sam made their way to their desks. William's heart sigh as he noticed the desk littered with red ink, an apparent love declaration or a sign of the ongoing hostility. He sighed, do those girls know how hard it is to clean their love messages. Although annoying, he didn't refuse it, afterall, they are his fangirls.

The classroom buzzed with whispered conversations until the door creaked open. In walked a man of impressive stature, reminiscent of Arnold Schwarzenegger in his prime—muscular, broad, and imposing. His presence commanded attention, and the room fell silent once more.

The man was their homeroom teacher, he said with a booming voice. "Good morning, class. Today Mr. Damon, will be our guest speaker today. He'll be here to give you some kind of a pre-orientation for what's to come."

A murmur of respect swept through the room as Mr. Damon entered. He was in his mid-twenties, with striking blond hair and piercing brown eyes. His tight-fitting white shirt outlined his well-defined muscles, and his black trousers completed his polished look. Despite his striking appearance, the girls' gazes didn't linger on him. To them, William remained the true object of fascination.

Mr. Damon stood at the front of the room, a bit awkwardly, as if trying to adjust to his role. He cleared his throat, trying to appear more authoritative. "I understand you're all eager to hear about the military academy. As your teacher has informed you, I'm a teacher from Military Academy 3."

The students exchanged respectful nods. Mr. Damon's smug expression grew. That's right, you folks, he thought to himself, I'm a teacher at Military Academy 3.

He continued, "I'm here to give you an overview of what's coming up. I need you to listen attentively, as this concerns your future." His serious tone drew the students' focus.

William straightened up, intrigued despite himself. Mr. Damon took a black marker and drew a large sphere on the whiteboard. Underneath, he wrote "Earth" in block letters. He gestured to the circle. "Consider this circle as Earth."

The room watched intently as he proceeded. "One hundred years ago, Earth was on the brink of destruction. Civil wars and nuclear conflicts between countries in which many died ravaged the planet. It was a dark time."

He drew a spaceship approaching Earth and used lines to illustrate its descent. "As if to punish us, a spaceship arrived. It wasn't here to save us. Onboard were demon-like creatures of unkown origin with elemental powers, bent on doing only one thing -destroying humanity-, countries joined arms to resist them but even normal guns and bombs do not work on them"

The room gasped collectively. William leaned forward, captivated. Mr. Damon drew an eagle on a shield and continued, "In humanity's darkest hour, several families with supernatural abilities, known as The Originals, stepped up to fight back. With their unique abilities and knowledge, they managed to drive the beasts away, now note I said drive away not win, the beast retreated to another planet."

He showed the spaceship departing Earth and heading to another planet. "The Originals knowing that the beasts will surely return then began to share their knowledge—soul essence and abilities—with the public, believing that if the beasts return, they will be in for hell of a surprise. Thanks to their knowledge and the use of abilities for advanced technology, Earth made remarkable progress."

He drew various technological advancements, including transportation portals which enable humans travel between planets to kill the beasts residing on the planets and to mine variuos materials from several planets. "Despite our progress, the threat is far from over.

That's why a global law was enacted: every sixteen-year-old must attend military school for three years to learn fighting skills and abilities."

The students' faces grew serious. Mr. Damon's tone softened slightly. "Now, this doesn't mean you have to become soldiers after graduation. The goal is for you to be able to protect yourselves and your families in case of a beast invasion."

With that, Mr. Damon concluded his speech. "That's all for today. I'll leave you in the capable hands of your teacher. Thank you for your attention."

The students stood, bowing in respect. "Thank you, Mr. Damon!" they chorused. He waved and said, "I'll see some of you at the academy. I look forward to it."

The teacher then went to the front holding a paper. "Now listen carefully."
