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--!
Damn it! Are you on 
Abeno-san's side, stomach?
Verdammt! Bist du etwa auf
Abeno-sans Seite, Magen?
¿Es que estás de su lado, estómago?
Sale traître. Depuis quand
t’es l’allié d’Abeno, estomac ?
Droga! Você está do lado
do Abeno-san, estômago?
