ESPer

Abilities appeared in Itsuki's world 25 years ago. Various incidents and calamities occurred, and by researching into the cause, it was discovered that each human possessed various abilities. They're also called PSI and ESP, I think. First, all the people with powers were each gathered into schools. There was one per prefecture. Though there were some exceptions. Powers are ranked from F to S, and classes are divided based on that rank. Of course, that also depends on the school.

The world didn't contain nothing but power users, there were also zeroes. In fact, there were more Zeroes than ESPers.
