Ascension of the Holy Dragon Berserker Knight?

Airi was once the Queen of Dragons a Dragon of Golden Holy Light. She was sacrificed (sort of) by her best friend to usher in a new era 10,000 years ago. Using her as a Catalyst her friend now an ascended god created a system for her world. This allowed creatures, humans and demi-humans to level up and evolve. After 10,000 years of drifting consciousness she has awoken with her holy powers restrained and seemingly turned into a vampiric dragon?! Her memories were also restrained and she must level up evolve and learn the truth of what happened 10,000 years ago while regaining her powers. Just one problem. After waking up and finding her way into a town that was near place of slumber she attempted to get information from a cute girl who forced her into a blood pact?! Now if the young girl dies so will Airi! With such a hiccup she now needs to help this young human girl get stronger alongside her or she would have a major weakness.
