While Nene is investigating abnormal magic signals, she realizes that Mangetsu lies at the center of the astronomically high readings. Meanwhile, as Kuon is thinking about her older sister Shisui, who has long been asleep due to a curse, she somehow receives a message from her. She heads toward the location indicated in it and finds none other than the one responsible for the curse: Suishou.
And you have to be the last 
one left at the end, right?
وينبغي أن تكوني آخر واحدة
متبقية في النهاية، أليس كذلك؟
Und du musst als Letzte übrig bleiben!
E alla fine devi rimanere solo tu, giusto?
E você tem que ser
a última sobrevivente, né?
И тебе нужно победить их всех, 
оставшись последней?
