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.
I'll go back to the way I 
was before I met all of you.
werde ich wieder so sein wie ich war,
bevor ich euch kennenlernte.
regresaré a un estado 
en que no los conocía.
je redeviendrai celui que j’étais
avant de vous connaître.
tornerei com'ero prima di incontrarvi.
eu vou voltar a ser como
 antes de os conhecer.
то я стану таким, каким
был до встречи с вами.
