Midnight is a Pro Hero that is also a teacher at UA High School. Her quirk is Somnambulist, she generates a aroma around her that will put any who breath it in to sleep. 

Midnight has two Enhance abilities. The first one requires her to commit and then allows her to discard any number of cards from her hand to draw a card for each one discard. This effectively lets her cycle her hand any time an attack is played. 

Her second Enhance ability requires her to commit a foundation and it gives the current attack plus one or minus one speed for each of the attacks keywords. This ability is also playable while committed which means Midnight can use her top Enhance to cycle her hand and then continue slowing down her rival's attacks or making her own attacks faster.
