David Argentino is a troubled youth who is about to begin a school year in a distant future where wars and revolutions have plagued the Earth, and where, at an unknown location, the world's largest school still stands. The school is Saris, a prison-like institution, run with an iron fist by the tyrannical principal known only as Headmaster. Battling depression, and a need to escape his past, David struggles to fit in. He meets the sensitive Marie, and love ensues. David delves deeply into intense soul-searching that eventually leads him to a breakthrough from his inner struggles. With the help of an angel called Sevens, his newfound freedom sparks a zeal for personal salvation from a dystopian world that begins to permeate throughout the school. Seeing his sinister plan for the students threatened, Headmaster embarks on a manipulative campaign to bring down the figurehead of this new uprising, resulting in a clash of wit and will, and battles with words and weapons.
