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--
There were no classes the first day, 
so I was simply shown around the school.
Am ersten Tag fand kein Unterricht statt,
darum wurde ich in der Schule herumgeführt.
El primer día no tenían clases,
así que me enseñó el edificio.
Samedi, comme il n’y avait pas cours,
j’ai simplement visité les locaux.
Não havia aulas no primeiro dia, então
eu simplesmente andei pela escola.
