A voyeur is regularly sneaking a look at the girls' bath, and the students are tasked with catching the culprit. Meanwhile, Jail attempts to find out more about this timeline and figure out why Nana sent them here.
I found a letter, sent to me
from the future, from me.
Eines Tages lag plötzlich ein Brief da.
Encontré una carta para mí,
Un jour, j’ai trouvé une lettre.
Encontrei uma carta vinda do futuro,
enviada por mim mesma.
