After clearing his throat the professor began.
"I am sure, no, I HOPE that you are all aware of the exam tomorrow", he projected loudly to the crowd of students. He took note of the few with their upper bodies sprawled on the small desks in front of them, fast asleep.
Striding quickly between two lanes of desks, the professor smacked a young boy upside the head, effectively startling him awake. The boy was not more than 12, but was sitting in a class of those at least six years his senior.
"Mr. Hatake", he said calmly as the boy rubbed his head. "Please remind the class the exact date that WWIII began".
As he made his way back to the pedestal at the front, he boy replied with a frustrated sigh. "2047, sir".
"Correct. What caused the war?"
Hatake sat up higher in his chair, trying to wake himself up for the long run of questions he knew was coming. You would have thought by now, at the end of the year, Professor Ingrid would know he was capable of answering every single question thrown his way.
"The experimental bomb launched by the Americans, which effectively turned London into a pile of rubbish".
"Correct. What happened next?"
"The consequences of that new technology was not only the physical damage and lives lost, but also what it did to life surrounding the destroyed area. Humans began to either die horrible deaths or morph into something that was foreign to them. They gained abilities they did not understand, and research suddenly took priority over making the Americans take responsibility."
"But London and the era around the city were not the only areas affected - "
"Correct professor" he said with a smirk. "The chemicals traveled through the air, through water, and did not dissipate over time. It spread across the planet in as little as a week. The whole world got stronger, and then everyone wanted to prove they were better".
"A grim past, that has led to our present" Ingrid nodded. He turned to the large monitor behind him and pulled up two maps, side-by-side.
Professor Ingrid continued the lesson without bothering the student for some time, which let Kakashi Hatake relax in his seat. He hated speaking in front of the class, even though he knew he was right. There was never a question of that fact.
The professor made sure to go over key points, a nice review for the exam that was almost upon them. The one that would determine if he was fit enough to have the future he desired.
Ingrid reminded them of the tragedy their ancestors lived through. The incredible geological changes Earth experienced in such a short time. Kakashi looked at the two maps, they compared Earth from 2048 to today. They looked like two different worlds. They were.
"With so much power at their disposal, our ancestors began the most cruel experiments on their own, in attempt to create something strong enough to finally win the war. However, the process and results of said experiments doubled, if not tripled the head count" his said grimly.
A young woman spoke, "like, what was the deal with the experiment?" Ingrid and Kakashi both gave a mental eye roll at her tone and use of the word "like".
"No one even knows exactly which nations succeeded at the creations, there was so much chaos and the population was disfigured. The product was a human that was stronger and more terrifying than anything we have even experienced in today's age. The beasts couldn't see right from wrong, could not follow orders, they didn't know who they were when they snapped. They barely got them back under control..."
Ingrid looked at his shoes, and realized how worn they looked. Kakashi's voice brought him back to reality.
"Sir, what was the overall death toll?"
Looking at him with a blank expression, Ingird responded.
"Over 90% of the entire population."
