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--
He was here when we said 
we were going to the store.
Als wir zum Kiosk wollten,
war er noch hier.
Abenon estaba aquí cuando nos fuimos.
Pourtant, il était encore là
avant qu’on aille à la cafèt’.
Ele estava aqui quando
falamos que iríamos à loja.
