Anna

About
Anna is a servant of Toushin Manor, the personal maid of Toushin Seed Cashima. As a Toushin's maid, she is privy to the manor's innermost secrets, namely that the Toushin are Angel Eaters, who require a special medicine, R334D, that kepes them alive but drives them into a sexual rage. Anna administers the medicine to Seed in addition to her general duties as a maid, such as cleaning or maintaining his schedule.

Anna is also subject to Seed's every demand, though he will only give especially demanding orders of her if she is corrupted by Sin. Mistreating Anna is one of the actions potentially punished by the Oni King.
