As a hero, Meguru wants to investigate the "black rose man" who's been causing trouble around the school. Miruku, thinking that it's dangerous for a middle schooler to be walking around by herself, asks an elderly male friend of hers, Nagatsuki, to accompany her. What will their investigation reveal?!
That's where we were 
out on patrol yesterday...
...لقد كنّا نقوم بدورّياتنا هناك بالأمس
Da waren wir gestern auf Patrouille.
Fue mientras patrullaba ayer…
Fue mientras patrullaba ayer…
C’est là qu’on a patrouillé hier…
È successo ieri mentre eravamo di ronda...
É onde estávamos de patrulha.
Мы там вчера патрулировали...
