Concrete Revolutio

It is the 40s of the Shinka Era... In Japan, "superhumans" such as giant aliens, super robots, and monsters were active. While causing mysterious incidents, the "superhumans" at times stop destruction and save people. Jirou Hitoyoshi belongs to the "Superhuman Bureau," which works to register and protect such superhumans, and he has come to scout Kikko Hoshino, who is working as a server at a café. She is a "witch girl" type superhuman. And right in front of Jirou and Kikko, a battle between Grosse Augen, the superhuman of justice, and an "S" Planetarian unfolds, leaving Jirou and Kikko no choice but to join in the battle.
