A yokai named Egen is scheduled to visit the mundane world.
Egen, who dreams of establishing a school in the Underworld, will be observing Abeno and Ashiya's high school for a limited time. Ashiya does his best to help Egen. However, Abeno's foul mood leaves Ashiya bewildered.
There's something bothering Abeno about Egen's visit, but Ashiya is completely unaware of what that is--
Not many yokai would fearlessly 
travel to the Birdcage.
Nicht viele Yokai würden
furchtlos zum Vogelkäfig aufbrechen.
Des esprits qui s’aventurent
dans la Cage du Passereau,
Não são muitos yokai que
viajam sem medo para a Gaiola.
