The Supernatural Studies Club meets Miyamura's sister, Leona, in their search for the seventh witch. She has dropped out of school in order to escape from that witch's power to erase memories. The instant one learns her name, all of their memories related to witches will be erased.
If you're determined to stay 
any longer, I'll show no mercy.
Erwarte keine Gnade,
wenn du dich nicht verziehst.
Si te rehúsas a marcharte, 
no tendré piedad contigo.
Si te niegas a marcharte, 
no tendré piedad contigo.
Si tu tiens à rester,
c’est à tes risques et périls.
Se hai intenzione di restare
 anche un altro secondo, non avrò pietà.
Se você está determinada 
a ficar, não terei piedade.
Если ты решила остаться, не жди пощады.
