Trivia

• In this Mirror World, Faust is a Proselyte of the Index.
• This is the first Identity to require three different Sin Resources to activate a Passive.
• This Identity's Morning Greeting mentions a Prescript which has Faust "drink a liter of juice and warm up" in the morning. This is a reference to a line in Children of the City, the song which plays for an important Index Messenger's Reception in Library of Ruina.
