"Concrete Revolutio is packed with more superbeings than you could possibly ask for. There are traditional sentai warriors here, and child geniuses piloting giant mechas. There are massive beasts created by government experiments, and cyborg detectives sworn to protect the peace. There are forces of nature and forces of darkness, invincible warriors and self-destructive terrorists. There's even a robot girl called Earth-chan who floats in space and answers the prayers of those who call for her using her mechanical star-antenna."
