Psychic Academy Series by Katsu Aki

Ai Shiomi is pushed into attending the Psychic Academy, a place of learning for psychically gifted students. Not only must he live up to his older brother's heroic reputation as 'The Man Who Stopped the Evil Lord,' but he must also deal with the fact that his brother is now a teacher at the academy!

The school year is coming to a close, and that means one thing: final exams! Ai is pretty confident about the academic part, but as for the psychic tests, let's just say his head is spinning. And to make matters worse, some of the envious students are setting out to make sure Ai's first year at the Psychic Academy is his last. Attendance is definitely required for this next volume of Psychic Academy.

A mysterious new girl named Faafa sweeps into school and enchants Ai with theromantic notion of ditching class, a way to achieve true "freedom."
