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--
Perhaps that's why he didn't say anything.
Womöglich hat er deshalb geschwiegen.
Quizás por eso no dijo nada.
C’est sans doute pourquoi
il n’a rien dit…
Talvez seja por isso
que ele não falou nada.
