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--
I was so sore, I slept all day on Sunday.
Ich war so fertig,
dass ich den ganzen Sonntag geschlafen habe.
me pasé el día durmiendo
porque me dolía todo.
Comme j’avais mal partout,
j’ai passé mon dimanche à dormir.
Eu fiquei tão dolorido,
dormi o domingo inteiro.
