The Amazing Seven (Japanese: アメージング７ (セブン) Amējingu Sebun) are a set of myths that happen around Y-Academy. Similar to the previous set, some of them focused on human characters and some focused on the Onryo encountered during their inception.
Obtaining all seven of the Mystery Medals unlocks entry to the third mysterious Y-Circle monument, where a Yo-kai named Mikettio resides.
They are covered in the Y School Heroes anime series, lasting from episode 24 to episode 32, except episode 30 and episode 31.
