Well, knowing that their dreams involve a lot of blood, bizarre imagery, penis-esque things, and some random NPCs are pursuing them, it's not hard to think they are not very social.
Hell, they all even have an ending in which they kill themselves. You can easily guess they three are depressed and in dispair, surrounded by sorrow and pain. Just look at those motherfucking dreams, for every nice place there is, you have, like, 4 or 6 areas full of grotesque scenarios.
And if that shit was not enough, look at how other people are reflected in those dreams. Mado sees them as faceless creatures that somehow don't even know how to speak; Uro sees them generally distorted and amorphous; And Sabi just sees fucking monsters and blood-covered people.
Even if we're not talking about rape here, you can easily see they are really afraid of the outer world. They don't even get out of their room!
As for personality-wise, Mado seems to like Paraca's thing, and reading.
Urotsuki seems fond of a lot of things, from video games to clothes, although her own fears appear to make hard to her to involve in such tastes.
And Sabi… well. You know. Sabi seems to live in a slum, but somehow she doesn't fit that place. I daresay she might have fallen really down but not because she was there in first place, but due to some external event. She seems to be a smart girl who sadly got a shit-ton of problems in her life and she sadly ended there.
