The words Nil Admirari mean “to be surprised by nothing” in latin which I guess perfectly the describes the fantasy story & twists that happen in this game. The word tenbin means scales so I’m guessing the title translates vaguely to “the balance of no surprises”. The subtitle refers to the roaring 20s “empire” in Tokyo, that the story takes place in and refers to it as ~gorgeous~ but that’s a coverup for the dirty truth underneath. Kuze Tsugumi’s family has been struggling financially so she’s decided to try to help her family by marrying some rich guy, despite the protests of her clingy otoutokun. Shit gets weird when one night her brother Hitaki mumbles crazy shit and then sets himself on fire. (He doesn’t die just goes into a coma and has a fever at the hospital.) Apparently a book that he read cause him to do this and it’s known from previous incidents according to 2 detectives who come to her house. After this event it seems like Tsugumi sees an aura-like fire on the book when no one else does. They ask her to join their police force unit Fukurou so they can use her powers to help find more of these cursed books(希モノ). They offer her a salary and a place to live and since her engagement appears to be called off, she cuts her long hair off & joins them. Her job is mostly to go around bookstores and check to make sure there’s no cursed books there. And while spending time with the guys at Fukurou, she’s about to learn some things that she was never taught in school ( ͡° ͜ʖ ͡°).
