The Twilight Seven (Japanese: トワイライト７(セブン) Towairaito Sebun) are another set of myths that happen around Y-Academy. Unlike the Seven Academy Mysteries, they are notably found outside of the campus most of the time.
They are covered in the Yo-kai Watch Jam - Yo-kai Academy Y: Close Encounters of the N Kind anime series, lasting from YG009 to YG015.
