Aurora Vespera (暁薄明(アウロラベスペラ), Aurora Besupera; Latin and Japanese for "Dawn and Dusk") a loyal and devout follower of Dorothy Furlan da Liberi, is the last member of Dorothy's Army. She is an incredibly unique entity and one of the few hybrids to exist as a human turned Diabolus and Daemon Witch. She was instrumental in Dorothy's escape from hell, due to her unique power Cogitanti Speculum which allows her to resonate and manipulate any barrier; including the Gates of Hell. She also serves as the support analyst in Dorothy's Army, providing intel and coordination, making her one of its most highly valued members.
