Indigo

Overview

In the middle of the 20th century, people with abnormal development began to be born in the world, who were called indigo. But few know that there are those whose anomalies are hidden, and the indigos themselves call them sleepers. The appearance of indigos began to threaten the established world order, so a hunt for them began in secret. To save themselves, indigos began to recruit sleepers using lists with their names.
