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?!
I'm sorry to make you walk 
around so much for nothing.
.آسفة لجعلك تسير في كلّ مكان بلا أيّ نتيجة
Tut mir leid, dass wir Sie so für nichts und
wieder nichts herumgescheucht haben.
Perdón por hacerlo caminar por nada.
Perdón por hacerle caminar en vano.
Mi dispiace.
Desculpe fazê-lo ficar andando à toa.
Простите, что вам пришлось 
столько ходить попусту.
