Reishoujo Mako

In every school there are very unusual characters. Take, for example, a quiet and seemingly unremarkable girl named Mako, who turns out to be an extremely gifted psychic. The school where Mako studies is beset by a series of supernatural disasters caused by a mysterious entity, which becomes the clairvoyant's primary task to track down and neutralize - because if she fails, all the school's students will be in mortal danger!
