Haruhi Hydra

Haruhi Hydra (ハルイ ヒドラ Harui Hidora) is the former queen of the Pro-Dragon Faction. Or, she was publicly at the very least. Despite being mated to the self-proclaimed Emperor of Dragons, Jormungandr, Haruhi was never a being considered worthy of respect by him. Considering her a sub-par dragon, he only mated her due to her popularity and affection from the subjects. In short terms, she was a trophy wife. Jormungandr's immense and incomprehensible might made him superior to her in basically every conceivable way, and as such, she became little more than a breeding machine to lay eggs and produce powerful offspring for him.

After years of submission and ridicule, Haruhi eventually managed to develop a form of magic which she hoped could elevate her to a level beyond Jormungandr: Elemental Sovereign Fire Dragon Slayer Magic, AKA Abaddon Dragon Slayer Magic, a supreme element which stands above even the likes of Dual Elemental Dragon Slayer Magic. However, she did not manage to finish it in time before disaster struck. Towards that which she would refer to as "The Begining of The End", the day where the Dragon King Festival would take a turn for the worse as Acnologia himself arrived at their doorstep. Fearing for her life, Haruhi took flight and flew as far away from the upcoming battles as she could, developing her Sovereign element along the way.
