Nice to meet you again too, Narukami-san. [Minato's expression doesn't betray anything but he did consider that he might have called Yu by his first name if they knew each other, only to decide against it since he doesn't remember if they were close at all.]

...Say, if we knew each other before this, it should be alright if you tell me if you need some help, right? [If not back to his apartment, at least some of the way.]
