Undead Unluck: Fuuko's Favorite Manga

This is from Episode 19 where Fuuko explained to Juiz that she read an shojo manga called, "To You, From Me," which was a book that shows both past and future events of the world due to how certain story arcs detailed the past while locking away the future events. The manga itself had over 100 volumes and Fuuko read them all in her childhood.
