Vagabond Rusher

A world where magic is possible and considered reality in a sense, Mahou Academy has been built to enhance and further nourish these talented magicians known as Artists. This academy ranks certain power, with F being its lowest. Shiki Shinjirou is one of those F, having no magic at all. Alone since birth, he never considered looking for his parents and sought out to just live his life normally until he dies of old age. His expectation changes as he tried to save a girl in the alleyway from a group of delinquents. He learns the hard way how life is with people having powers and abusing them. He later realizes what differs him from the ranks, how he himself became the "Vagabond Rusher". His only choice of strength? "Andrenaline Rush". How he does it? An energy drink.
