Amora of Artemesa -- Breaking

Artemesa is run by a fierce hierarchy. Only those with political power or powerful Amora can live comfortable lives. Those who don't have noble titles or low-tier Amora are trampled under the feet of the strong, especially the Royals. The hierarchy dominates not only Artemesa as a whole, but even individual workplaces or households. At the Fifteen Diamonds of Artemesa, that holds doubly true. The Fifteen are known as school for the elite and privileged. And the Royals at Luminine, one of the Fifteen, were seven of the strongest Amora users in the world. They were known as God-tiers. The King and the Jacks were known as the Cadre of Luminine. The Cadre was led by an extremely powerful individual, known as the Queen. Her given name was Asha, her official last name unknown. Asha was granted a noble title by the King, and was known as his Watchdog, his Sword, the piece he could move secretly and freely in the shadows. - In this first book, the Cadre is hit by a sudden insight into Asha's past. While it's not everything, it's more than they'd ever known about her before. A mysterious girl dressed all in black with skeletal wings appears on the scene, just as Asha leaves it. During the Interschool Tournament, a dark horse appears and threatens to take down everything Asha sought to keep safe. The Cadre were forcefully dragged into Asha's personal life, one they found to be much more dangerous than they thought. And while the Cadre and their Queen are away from the school, a war breaks out between the Fifteen Diamonds. Asha must protect the school, her cadre, her plans, at herself all at once. She seems to be fighting a three-fronted war against the monster inside her, her brother’s plans, and another puppet master behind a more sinister plot. - This book is about Asha's Breaking
