Get to know Louise, a young magician in the making. Her current record of zero achievements with magic has earned her the nickname "Zero Louise" among the pupils at the Tristein Academy where she studies. In point of fact, most of the time her magic ends up in a hilariously disastrous way. The next step in this significant evaluation of her skill with magic requires her to conjure a familiar to serve as her attendant. At this crucial juncture, she channels all of her magic and makes a wish for a familiar that is "devoted, attractive, and powerful." Instead, she gets Hiraga Saito, a typical Japanese teenager. It's hard to say who is more shocked and disheartened, but the regulations don't allow for any more chances to try again. Louise is unable to escape her weird familiar, and he is unable to escape Louise.
