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--!
If he can't find me, buy me 
some ice cream, Haruitsuki!
Wenn er mich nicht spürt,
kauf mir ein Eis, Haruitsuki!
Si no lo logra,
cómprame un helado, Haruitsuki.
S’il perd encore,
achète-moi une glace, Haruitsuki !
Se ele não conseguir me sentir, compre
um sorvete para mim, Haruitsuki!
