Intro. The story is set in a world where magic has been scientifically described and thus made technologically usable. People with corresponding talents can charge a device called a Casting Assistant Device (CAD) with their thoughts using psions—spiritual particles—which then activates the intended summoning sequence, altering the eidos, i.e., the information or properties of the affected object. The time of the story is the year 2095, 35 years after a 20-year-long Third World War that was decided by this modern magic. In Japan, the First Magic High School was established with the purpose of training magic-gifted youth. Each year, 200 students are admitted in two equally sized groups: the first group (also called Bloom, "flowers") consists of those who receive actual training, and the second group (also called Weed, "weeds").
