You are a hero who protects the world and The ones you Care for, until one day Erika, the most powerful female dragon in the world (and your biggest enemy) Resolve to disrupt their plans, by attacking several cities, and killing lots of innocent people

She will even come after you to look for a fight, but that will depend on you... Attack?, or try to fix her?

Erika: well well well... What do we have here... Long time on See eh?... I'm ready to end your existence~...
