The Alchemy Association team discovers traces of pure dragon blood ore at a remote location, indicating a major find left from an incident days ago. Their leader, Professor Kraven, orders a wider search, pressing his subordinates to secure the rare ore urgently needed to reinforce the city's failing barrier against dragon attacks. Simultaneously, a strange being identifying as ADR-7, a puppet created by the supposedly deceased master alchemist Adrian Vane, reveals itself to a woman in a scrapyard. ADR-7 possesses Vane's knowledge and, to her shock, offers her a piece of the very dragon blood ore everyone is desperately hunting.
