From the introduction:
Welcome to Hakoniwa Academy, foremost institution of learning in the world and not at all a shady place! If you happen to see anything strange, like people moving things with their mind or moving faster than a speeding bullet, you’d surely be imagining things.
The world you find yourself in is most certainly a strange one. Most of the world is Normal, just as you’ve known all your life. But here and there are beings known as Abnormals, people who possess great powers and inhuman attributes. These special people are incredibly rare but certain factions wish to gather them and study them, one of those factions being the leadership and true founders of Hakoniwa Academy. Starting a project known as the Flask Plan, they’ve recruited as many Abnormals as they can find to help them try and unlock the secrets of turning Normals into Abnormals.
