There are two names given
here, with the note that there are "6 other people in total" If you're looking for the two girls on the front and you're lucky, then maybe it's these two. In any case, you will need to somehow identify who these two names belong to (and since it's in kanji, there might be different readings, but seems like the first one given there is Rina, and the second one is Maho)
By the way, since I haven't watched any JAV like that yet, does it feel a lot different in how it's staged etc.? I mean compared to straight stuff. Maybe there are far more dialogues etc.?
P.S. Well, I guess since it's kind of a "pick-up" premise, there would be just as much talking in straight JAV. My another guess is that there might be much more feminine talk (one of the features of Japanese) and even the "mature" and "young" woman styles of speech etc.
