I think I can let a few things slip, at least from some of the NPC's already shown.<br/><br/>Sayomi:  She's actually put her rape behind her as best she can.  To her mind there are more important things, like making sure her home is a stable one for her son.  Whom she loves like any mother should.  How she got him is not important, that she got him is.  Any sort of tightening of the eyes is more about how she wishes she could somehow make his life 'normal'.  She's a little worried about the lack of girls, and she's not so sure about the strange men he sometimes hangs out with (She doesn't know they're Yakuza) but as long as he's happy and safe, she doesn't really care.<br/><br/>The Twins: They aren't really.  They may look it, but Ichigo's mother, Ayane, based them off her original prototype.  Unit Zero, Rei.  They are, in fact, two halves.  And yet, not quite.  After she gave up part of her soul in making them, they started to grow on their own.  Thing is, they don't realize it and hold themselves back.<br/><br/>Nisen:  As everyone knows by now, he's the introvert of the pair.  His skills are mainly with his hands, which is why he runs a tailoring business.  The Ningyo Moonlight Cloth Studio.  But like Sanro he's also designed as a protector, so he's got weapon skills, and in a Japan with strict gun control laws, that means mainly martial arts style weapons.<br/><br/>Sanro:  The extrovert, he genuinely likes people to boot.  His teaching style is rather unique in a stratified school system like Japan's, but he doesn't care.  And most of the students love him for it, which is why he's still employed.  And like his not quite brother, he's also a fighter.  But his specialty is barehanded techniques.<br/><br/>Thing is that both men are starting to lose their 'professional' demeanor around Ichigo.  She's no longer the little kid anymore, and not having a childhood of their own, they're starting to test the waters with her.  Thing is though, they've also started to look outside their home for 'company' to stave off any odd behavior around her.  And being model class, means they don't need to work for it very hard.<br/><br/>Rei:  This guy is one fucked up piece of work.  Everything he does is based on possession and he believes that anything Kimekomi is his, to do with as he pleases, including his own daughter.  And he's not afraid to kill to get what he believes is his.<br/><br/>I think I can let that go for now.  :)
