That evening, Makizawa Sota gathered all the members of the Defense Society and inspected everyone overnight, but no other Shadow Men were found.
This did not surprise anyone, the opposing force would have already retreated their people knowing they have been exposed.
The method of inspection involved rotating a light source above a person's head and observing whether the changing shadows conformed to the laws of physics.
Even if those Shadow Men could manipulate the direction of their shadows, under such impromptu high-speed inspection, it would be impossible for manual manipulation to keep up with the changes in the light source, they were bound to give themselves away!
Upon learning that entities from another world had infiltrated the higher ranks, the Japanese government finally took the matter seriously and urgently instructed all departments to conduct a self-inspection overnight using the method provided by the Exchange Group.
