Bouga Kyoukai: Kanma no Niwa

Strange events are taking place at a certain academy.
While rumors were spreading of the uncanny “Seven Wonders,”
certain individuals who had the unique powers of “Awakening,”
in who manifested the existence of beings known as “Angels.”
For the sake of reaffirming reality,
for the sake of protecting your loved ones,
—you must face them.
