Vulcan is a very skilled engineer with a love for animals which often bulids his machines to an animal theme. His goal in life is to build something like his family's Amaterasu to supply enough energy to the world in order to save the world's endangered animals. Despite his grand ideals he desires to remain independent.
This is rooted in his total hated for Haijima Industeries as he blames them from the death of his family. This also means that he has a total distrust of the Special Fire Force's requests for him to join their organisations.
Vulcan is very passionate about his occupation and loves creating new inventions.

Vulcan becomes the Engineer for Special Fire Force Company 8.
