Hm... Yeah, Aqua for heroine, all the way. If we're gonna get an ahegao sex slave might as well be a useless goddess. Plus, water. It's almost poetic.
...dat moment when you comment the credits meme before the chapter.
@Phelix I see your point, but as I always say. Different world, different rules.
MC is a Sadist, that much is clear. And every S&M relationship has a sadis and a masochist. In a real world S&M, everything's consensual. It's not rape.
And this the same. Girls go CRAZY in heat just with a touch, deal with it. They want the D, and will gladly do anything to get it (look at Lumi, she asks for it even without being touch-aroused). They're doing that willingly (sort of. It's the only D in the world, so it's not like they can choose another one. But they can choose to keep their distance). So MC plays the S role to his heart's content and the girls comply as good lil' Ms.
And he's not even a bastard, like some people say. He doesn't tie them, hit them, or hurt them in any way. Just a bit of verbal abuse, and not even that much. He's not calling them useless pieces of shit or anything. He calls them bitches in heat (which they are) and teases them by talking about their anuses and stuff.
I get S&M is not for everyone, but really, he's nowhere near as bad as people want to make him. A couple of chapters ago some were calling him a straight up rapist. Like, really bruh? Dude legit sends women to heat with a single touch, overriding any resistances they may have, but chooses not to use it on every single girl he sees, and even dodges girls so they won't go into a frenzy...but he's a rapist? Well, to each their own, I suppose...
Nagatoro is a WAY worse Sadist, abuser and piece of shit than this dude, and yet most people are fine with her, for reasons beyond my understanding.
