His daughter? Definitely unlikely - I believe she mentioned he was only 10 when he met the demon previously. Possibly the mom was someone who took care of him when he was down from all the abuse in his household.
She's got red eyes, he's got green eyes, Ruu has 1 red and 1 green eye. Notably a Demon having heterochromia is often used to denote them being a half-demon.
Now Let's be clear I'm not saying Ruu-Mother had sexual relations with a 10 year old. But we don't actually know how Succubi Reproduce. So it's not outside of the realm of possibility that he may be the father through non-sexual means.

I mean sure, but not particularly relevant. First boys often don't hit puberty at 10, but second I said it was "unlikely" not that it was guaranteed. Even in that gross series I read a synopsis for and noped out of long ago, he was 12-13.

At this point, both him being older brother and Ruu being little sister, and Ruu being the uncle's actual daughter, are equally likely to be the case; but I don't and I won't care, as long as I keep seeing these fluffy Manga pages I'll be happy.
