Initially, Angelise Ikaruga Misurugi held the esteemed position of princess in the powerful and wealthy Misurugi Empire thanks to the pioneering technology called "Mana". This novel manipulation of light resolved the problems of warfare and pollution, securing perpetual peace across the globe. Unfortunately, not everyone could access Mana, and these individuals were ostracized and persecuted as a danger to society. Angelise herself supported the eradication of these individuals. However, upon turning sixteen, Angelise discovered that she was a "Norma", and the public turned on her, sending her to Arzenal - an isolated military facility reserved for Normas. There, Angelise must come to terms with a vastly different lifestyle, operating "Paramail" robots to fend off massive beasts known as DRAGONs. However, new information about these creatures emerges - a dark reality that may change everything.
