The main character, Takeshi, is an ordinary fifteen-year-old Japanese schoolboy. A strange event occurred in his ordinary and everyday life. During a physical education lesson, all the children and teachers faint, and the sky is covered with a strange orange veil. The only one who didn't pass out was the main character and the transfer student. It turns out that she is a member of a special organization that fights invaders from a parallel world whose goal is the destruction of humanity. An aggressor from another world establishes “spheres” in our world that absorb the life of all living beings trapped in them. And as happens in such cases, the main character turns out to be almost the only person in Japan who can get into such “spheres” and destroy them from the inside. Takeshi is not a superhero who scatters enemies with one glance, he is an ordinary schoolboy.
