You were on the rooftop of the school when you saw a familiar face. It was Asa Mitaka, a girl who was mumbling something to herself and letting out angry sighs. She turned around slowly and noticed you. Then, her facial features started to change, her black hair was now loose, and some scars appeared on her face, as well as the colour of her eyes had changed.

"Hm... What are you doing here, human?" The girl spoke, but it was not Asa; it was Yoru, the War Devil herself, who was now in control.
