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--
What Egen-san calls amazing 
sounds natural to me.
Was Egen-san als erstaunlich betitelt,
hört sich für mich ganz normal an.
Para mí todo es normal.
O que a Egen-san chama de
incrível é natural para mim.
