25 years ago a bunch of teenage superheros, called The Wonders, made superheroes popular again but no one knows who they really are. Ryujin is born to superheroes but has no superpowers. Yet she wants to attend Sky High a superhero high school because she wants to be with Chaeryeong, her best friend.  Ryujin's mom has a bad feeling about this whole thing but trusts Ryujin anyway. And that's what you missed on glee.
