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--!
Yesterday I couldn't even stay 
hidden for thirty minutes,
Gestern konnte ich mich
keine 30 Minuten verstecken,
Ayer no aguantaba ni media hora,
Je tenais même pas une demi-heure,
mais aujourd’hui, ça va mieux.
Ontem eu não consegui ficar
escondido nem por meia hora,
