Shiori come and tells Kakeru and Misuzu everything about the red night and about the black knights. Lisette is actually Liselotte, who seeks to destroy the world, just like her lover, Verard wished for. 64 years prior, Liselotte was sealed away by Index. However, by doing so, the Disciples turned into hideous creatures who are now called the Black Knights, who guard Liselotte's seal. They also seek to destroy the 7 fragments of the "Void Stone" which were separated into parallel worlds (when she was sealed), but have now been brought together in the red night. If all the fragments are collected, Liselotte's seal will be destroyed and opens up the Hell's gate (which is the black moon, which will bring the end of the world).
