@HYBRID_BEING Good question. It feels like it probably is, but I'm not sure. If anyone has a better grasp of Japanese puns than I do, please let us know!
@Myorn Haha...I loved that line. I think that, given 04R1's modesty, she'd consider even the best Ecchi manga to be a crappy one. So, I think they're being self-aware through the eyes of the main character...maybe?
