Now that's another manga that should be made into an anime :D

Yuuko has purplish black hair, whereas Kirie has greenish (possibly black) hair.

And only now noticed that Kirie and Yuuko do share the same eye colour. So that part does appear to be dominant by the looks of things.

Just because her great grand aunt has certain features doesn't mean she has to inherit those features.

I mean, there's her grandfather and his side of the family, then the grand parents on the mother/father's side of the family.

That's a lot of genetic material, especially when you have to start dealing with potentially recessive genes as well.

Add to that, that it might be a side effect of the whole being a ghost thing.

Well, the guarantee that they'd have the same colour eyes, just because they're kinfolk goes right out the window.

Personality is like a blend of Senjougahara and Kanbaru, and with that I mean the good parts of their personality, rather than their negative sides.

So playful, teasing, secure in their sexuality.
And when the jealousy side does arise, it's aimed at the one trying to take away their Precious, rather than the Precious themselves.

why am i thinking about sex with ghosts?
