Several years after magic was brought to the world by an "Alleyway Lady" from another world, crimes committed by "Mages"—humans who acquired extraordinary powers through magic—had become a social issue. Kabutomori Ren, an ordinary person who failed his job hunt for the police force but joined the private magical organization "WALL OF MAGIC" to counter mage crimes, heads to meet Sumiharu Mina, the mage he will be supporting with his life on the line. It is a tense first meeting, but waiting for him there is... a girl who is still a student, playing with a soccer ball!?
