Overview#
It's a textbook that covers the history of Heroes, from their origins with the rise of the first Vigilantes, and the establishment of the Hero Licensing system.
Hitomi University's undergraduates use it for studying, but it can be a complicated book to read, so it is often recommended to copy notes from upperclassmen.[1]
