[WARNING: mature content. please skip if below 18] What would you do if you have a system that can summon minions ranging from—super mecha’s, sexy vampires, Cunning Demoness, naughty angels, War gods, Monster girls, and curvy goddesses to do your bidding??? The present Earth has turned upside down because of the high values placed on the superheroes who were treated like gods among men. Ruby Rose's mother was brutally murdered by a superhero who wanted to force himself on her. And his six-year-old sister, who tried to fight the big superhero, was also killed and chopped into several pieces. Ever since then, Ruby has lost the love he once had for the superheroes that have become role models for everyone. He trained for years, and after getting stronger, he decided to hunt down all the heroes one by one. However anytime he fought against them, he was brutally defeated, and he'd always run away. Then, they eventually did it. They finally captured him and threw him half-dead into a gloomy cave, but at the brink of death, his eyes snapped open when he saw a glowing purple crystal in the dark.
