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--
For all those who placed their hopes 
in me, I will make it a reality!
Ich werde diesen Traum wahr machen,
für alle, die ihre Hoffnung in mich setzen!
Y lo lograré.
Por los que ponen sus esperanzas en mí.
Je ne peux décevoir
ceux qui comptent sur moi !
Para todos aqueles que depositam sua
esperança em mim, irei tornar isso realidade!
