Chapter 1: Evolve Or Die!

Year 2025, Zimba, in a random city, time around 10 a.m. In a random school and a random senior high school class.

"Teacher, what are we doing today". A blonde haired cute girl spoke to her teacher standing in front of the class after raising her hand and being picked.

"Emily....sigh, we literally have a time table and a syllabus, how can you possibly not know what we're learning today?. I know you want to talk to this handsome teacher of yours but can you at least think of a not so obvious reason?". The teacher, a young man with short black hair and grey eyes replied to her narcissistically.

Hearing the first part of his reply, Emily blushed with embarrassment after being exposed in front of the class. But after hearing the second part, she couldn't help but role her eyes at this narcissistic teacher of her's. Even the classroom who were about to make fun of her lost the will to do so after hearing the teacher's statement.

Seeing how his word play had gotten everyone quiet, which was his desire, the teacher smiled at himself thinking he was so smart.

"Tsk, damn manipulator". Another cute girl, this time a brunette, spoke under her breathe.

"I heard that Layla, anyway let's get on with our class okay. Today we will be looking at..."

Just when the young teacher was about to address his class, he was interrupted. The interruption, not only interrupted him but everyone, everywhere. The whole world was interrupted, especially those who were having se...cough, point is everyone was interrupted.

"EVOLVE OR DIE!!!"

That's right, the interruption was a voice from the sky that everyone in the world heard... except for deaf people of course.

Because of the voice, many people who were doing something that requires focus died. The people who died the most were motorists, as even if one stopped in time before hitting those in front of them, it didn't mean those behind then would do the same. The roads were consumed in utter chaos accompanied by screams of agony and explosions everywhere across the world.

Even a couple who liked titanic too much and were re-enacting a specific scene on the roof with eyes closed. Where so startled that the lady fell off, blunging into the far ground. Dying on impact in a mess. Many who saw the scene screamed in horror.

At the same time, what appeared to be portals, manifested outside every human settlement. Outside these portals, beasts that looked like advanced versions of the animals on earth came out. All were at least the size of adult lions and none of them seemed to be vegetarians.

If anyone could perceive energy and where at the scene of one of the portals. They would have noticed how it wasn't only the beasts that were coming out of the portals. But the legendary mana everyone knew but no one had (like love in most cases these days) was also accompanying them into the world.

...

Back in the classroom...

"Sir Muku, what's going on?, what was that voice, what did it mean by evolve or die?. Another little beauty spoke, this time a green haired one. Fear of the unknown visible in her eyes, and in the eyes of every other student in the class for that matter.

"Calm down Jade, for now let's go to the assembly point, maybe the headmaster will....close and barricade the door now!!". Just as Muku was addressing his little students, he happened to look outside the window and noticed a scary scene.

Since the school was a multi floor building, his classroom was rather high up in the air and the school gate could be easily seen. When he looked at the gate, he saw a horrifying scene. The school guards were getting attacked and ripped apart by beasts that seemed to be mutant dogs.

They had, pitch black skin, long protruding canine teeth and were all at least a meter and a half tall. The scared guards couldn't even reach their weapons before they were ripped apart. Screaming for a few seconds before they were put out of their misery.

Witnessing that scene, Muku knew that they were screwed. The only thing his celebrated genius brain could think of was to barricade the door and hope that the monsters pass them by.

The students noticing their teacher's unfamiliar hysterical expression. All ran to the windows to see what was happening. They were met with a sight of black large dogs making their way into the school building after breaking down the steel gate, while a few well gobbling up the guards.

Many girls screamed, some froze, shaking in fear. Some guy peed his pants and bolted out of the room. As if that's what they were waiting for. All the boys ran out. A few of the girls ran out too.

"Stop you idiots, where do you think you're running to when they are coming from the only way out of here?!". Muku who had finally collected himself a bit, screamed at his students. But sadly his shout was mostly met by deaf ears, not many students stopped.

By the end of the episode, only he, Emily, Layla, Jade and one other girl were left in the room.

"Sigh, I was too late to act, well I can only keep these girls safe for now.". Muku very much wanted to go after his students but he knew there was no way they would all run in one direction plus it would just endanger the girls who remained.

So he proceeded to close the door and barricade it with desks. Then took down the red axe on the wall, took his chair and set down while nervously starring at the door.

"You girls stay away from the window and find a place to... Never mind". He was about to tell the girls to find a place to sit away from the windows but seeing how they all came and stood as close to him as they could. He shut his mouth knowing that there was likely nothing he could say that could get them to back off from him in that moment.

"Why do you all take a deep breathe huh, we wouldn't want a repeat of what happened with the other students to happen with you as well after all." Muku talked to them trying to get them to calm down their racing nerves.

Hearing him speak so softly, the girls took herd of his advice and started to calm down, even if it was only by just a bit.

"Sir, are we going to die?". Emily asked him with teary eyes and a shacking body due to fear.

Looking at her for a moment, then the other girls who were also asking the same question with their eyes. He sighed again, closed his eyes then opened them before speaking.

"No matter what happens, I, your teacher will protect you all with my life, so as long as I live, you will all be alive as well.... Of course if I die then you're screwed...Ow!!"

Hearing him speak so resolutely, the girls had all basically gotten their emotions in check. Though hearing the later part, Layla couldn't help but hit the back of his head.

"Did you have to say the later part?!". She asked him while glaring, but the visible smile on her face and the faces of the other girls showed that his attempt to lighten up the mood worked
