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--!
After you quit working for me, 
you'll have to protect yourself.
Wenn du aufhörst, für mich zu arbeiten,
musst du dich selbst schützen.
Cuando dejes de trabajar conmigo,
Quand tu ne bosseras plus avec nous,
tu devras te défendre tout seul.
Depois que parar de trabalhar para mim,
você terá que se proteger sozinho.
