[X] Don't be hasty and start from the beginning. Read up on Academy City and Espers.
There's no handy "Academy city 101" "Superpowers for dummies" book lying around, but you manage to cobble up some basic knowledge from books and the internet.
Academy City.
A landlocked sovereign city-state whose territory consists of a walled enclave within the Tokyo Metropolitan Employment Area. As the city's name suggests, it is a city of several schools and institutions of higher learning from kindergarten to university level that learn side-by-side along with the scientists who research on psychic powers and higher technology. It is so advanced city its technology is said to be 30 years ahead of the world.
Academy City is composed of 23 districts, called School Districts one to twenty-three. Its total population is about 2.3 million with 80% of them being students and 1/8 of those students living in the city dorms. Of the entire student population, only 20% possesses a power worth mentioning, while about 60% demonstrate only a slight amount of psychic ability, level 0, 20% pursue other subjects instead of going under the Power Curriculum Program.
That significantly cut down on the number of people who can blow stuff up with their mind, but still leave about ten to a hundred thousand of them packed in the same plot of land. The knowledge doesn't really bring you much peace of mind.
The city's first line of law enforcement is the security bots that constantly patrol the streets. They're the one who deal with minor offense or delinquency, leaving Anti-Skill, an armed militia equipped with Academy City's latest toys, free to take care of real criminals. There's also Judgement, a city-wide "disciplinary comittee" of volunteer students, depending on their abilities to support Anti-Skill.
You take a look at a map and locate your appartment building and school before moving on to Espers.
Espers are the name given to the people who developped a supernatural ability through the Power Curriculum Program. Through the use of training, hypnosys and drug treatment, they learn to manifest their Personal Reality, substituting the world's reality with their own. The concept is eerily familiar, but whereas your Reality Marble is engraved in your very soul, the Personal Reality is describing as a mental structure whose magnitude depends entirely on the Esper's calculating ability.
...You have an inkling as to why Emiya Shirou never progressed beyond Level 1.
You're not Emiya Shirou. Not this Emiya Shirou at least. While you seemed to have things in common, your mindset are different and you definitely lack that Personal Reality of his.
But if that power is born from the physical shape, then you might be able to learn it as well. At least, self-hypnoiys is the first step of a sucessful magecraft and your own skill depends on imagination. While you don't have the six years this boy had to work on this skill you have more than a decade on him in the practice of those. It's no garantee, but it's worth a try, you think.
You keep reading for a while longer, delving into details about the underlying theories that support espers abilities and the experiments the students goes through. You're not eager to let some mad scientist toy with your brain, but the Level 1 experiments aren't that invasive, even if some are outright brutal. You can handle easily enough.
The only question then, is if you are willing to take the risk. Espers release a form of energy called AIM, which is as unique to each of them as their thumbprint. If you have AIM at all, it is most likely doesn't match your previous hosts.
You'll have to think about this carefully.
It's past midnight now. You're not really tired yet, but there's only a few hours until you have to show up for school. You live in the district 7 and your school is in the district 23. While the two border each other it is still quite a distance on foot, especially when you don't know your way around.
Maybe You should take a day off to really get your bearings.
