Arc System Works describes the DLC.
While the incident in America triggered by Asuka R. Kreutz's surrender unfolds…
Special Brigade Commander Ramlethal Valentine heads to the outskirts of Illyria after receiving report of an emergency.
There she finds a girl who closely resembles “Bedman”, who once worked with the Universal Will against mankind.
The DLC will feature new characters not seen in the main story, such as Delilah.

A young girl who has awoken from a long slumber. She's lived within a dream since her birth due to a unique condition caused by her brain's inability to withstand her exceptional intellect and abilities. As she's only just woken up, she doesn't have a solid grasp on common sense and social skills. Her one and only motive is to get revenge for her brother's life.
