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.
Obtaining all seven of the Mystery Medals unlocks entry to the second mysterious Y-Circle monument, where a Yo-kai named Bluepon resides.
They are covered in the Y School Heroes anime series, lasting from episode 9 to episode 15.

Trivia[]
- The Twilight Seven are the first set to not entirely focus on Onryo, as both Kinya Daiouji and Kumako Kumoike are featured instead of the Onryo encountered during their myths, Kamagaeru and God Unchikumars respectively.
