After his planet is invaded by All-Conquering Overlord Hadris Torant, ordinary human being Orange ends up getting caught in the middle of a conflict ignited by anti-Hadris forces. And by caught in the middle of, I mean he ends up down a couple limbs and nearly dies. Thankfully Hadris' people take care of him and get him fixed up, and Orange decides he'd rather be on Hadris' side. He lucks into a position as an intern working right under the All-Conquering Overlord himself, and soon enough he ends up as Hadris' personal assistant. Orange ends up becoming involved in the affairs of Hadris and his closest aides - the Representatives - which leads to all kinds of wacky shenanigans and misadventures!

...Of course, an evil empire can't just be fun and games. It doesn't take Orange long to stumble into Hadris' darkest secret, a secret that threatens to violently reveal itself to the rest of Entirety any day now.
