graf michael sepperin
Graf Michael Sepperin is the leader of RKS and the biological father of Iris Sepperin. Thought to be the main antagonist of the game, that title is passed on to Iris after he is defeated.
Sepperin is considered the Dracula of Rosenkreuzstilette because he is based on the Dracula in Castlevania and can also transform into a large demon just like him.
