Wow I can't believe Kanda-kun just raped Ookuma.
I'm certainly no expert on the subject, but is it really that immoral in this context? The issue with stauatory rape is that the person can't consent, but if the two people involved are already a couple isn't consent assumed to a certain degree?
I'm not saying all examples of statutory rape are made okay if the two participants are already a couple. Definitely not. If Ookuma did sexual acts on Kanda while Kanda was unconscious or the like, that would definately NOT be okay. But in this case Kanda was under the influence of alcohol, but otherwise actively persuing sex with her girlfriend, something she'd be happy to do without the influence anyway.
I just think it's a bit harsh to call this rape, when I imagine there's a lot of couples in the world who've had sex while one of them wasn't in the right state of mind, and were perfectly okay with it afterwards.
