Ashiya's friends Saga and Fushimi invite Ashiy and Abeno on the photography club's overnight trip.
Since the incident with the Executive, Ashiya has been able to detect yokai at a distance.
However, he still hasn't mastered that skill, so Abeno uses the overnight trip to develop Ashiya's detection ability.
Yahiko is invited along to help, but a prank he pulls on Ashiya draws out another one of his latent powers--!
Anyway, Yahiko, no one asked you to 
make this a scary hide-and-seek game!
Jedenfalls hat dich niemand darum gebeten,
Gruselverstecken draus zu machen, Yahiko!
Yahiko, no añadas un elemento de terror
a las escondidas.
Yahiko, on joue à cache-cache,
pas à fais-moi peur !
Enfim, Yahiko, ninguém pediu para
fazer um esconde-esconde assustador!
