Hey-yo! So, this is an idea that I thought up of at one point for my One-Shot Ideas, however, it ended up being in the back of my mind, calling me, telling me to pursue it, so here I am, check out my One-Shot stories and leave a review if you want the same thing happening for the other stories. So with that out of the way, let's get on with the story!

It happened so suddenly one day, at first, it started out with just simple flashes out of nowhere, people just past them off as visions and wrote stories about what they saw. But then people started recognizing complete strangers, magic started to become more real, even a few sports and tournaments started rising in popularity.

But the worse change were the monsters, scientist ended up finding a low level monster and studied them, but they slowly started to increase in size, strength, and numbers, it came to the point where they looked ready to invade, and they did. Loses were devastating to any opposing military, but then came a mage.

At first the soldiers were ready to drag him off the field, but when they saw him cast a spell, taking out several monsters along with it, they gave him free reign, then came a ranger, a warrior, a knight, a priest, a rouge, and finally a berserker. The tides finally turned, and the monsters were finally killed.

However, this brought up some questions, how could they kill these creatures? Seemingly untrained civilians were able to do what battle-hardened soldiers couldn't? So they researched discovered, just as humanity has always done, and what they found changed everything.

Turns out, reincarnation had finally proven its existance, and with its discoveries came many changes, religions tried jumping the discoveries to spread their influences, but surprisingly, most priest that were found had said they were killed by cults eerily similar to the religions of today which was the cause of their atheism.

Military tried to capitalize on the potential military growth, but didn't need to as most knights had ended up joining willingly due to their vows. Scientist and mages joined together because of their love of research and discoveries, eventually, schools started popping up designed for RIs(Reincarnated Individuals).

With a remarkable 3 years, the entirety of the world had changed, and that is what lead to Izuku Midoriya heading to an RI confirmation test. To be precise, he was being forced to go by his former best friend turned bully, Kastuki Bakugo.

To be exact, an RI test were not mandatory, as many RIs had remembered their past and proven it without their help, but Izuku was listed off to have no potential to be an RI, by a famous mage with top tier prediction ability. However a prediction is just that, and to fully prove that he was useless, Katsuki wanted to confirm it live in front of the school.

Hence, the hidden camera that was recording the results of a test that had yet to come in. There were at least 200 viewers to witness Izuku's declaration of uselessness, and when the doctor finally came in, the viewer jumped another 50, "Mr. Midoriya, before I tell you the results of the test, let me ask you something, what do you know about the probability of cross-lives?"

This caught Izuku's attention as he responded, "The likelihood of a person with multiple lives right? Well, it's common for a person to have one life, rare for a person to have two, and extremely rare for a person to have three, such as Shoto Todoroki, is that right?"

The doctor nodded as he proceeded, "Yes, very good, while the only thing I can say to correct that is not every can be an RI, however, let me ask you one more question, what do you know about class probability?" Izuku thought some more, "Mages make up most of the RI, Knights being a close second, Warriors are third, Berzerkers are forth, Priest are fifth, Rangers are sixth, and Rougues are seventh, but that may be due to how they tend to hide from society as a whole so the results may be inaccurate."

The doctor nodded as he looked him straight in the eye, "Good, as you know, combining these two predictions makes the likeness of three happening unlikely to begin with, but, as your doctor, I will be proud to tell you this, I am only given the choice of telling you your cross-lives number, which is a resounding seven, congratulations Izuku Midoriya, you are the first of your kind."

And as that statement was said, the world would be thrown into a frenzy.
