I would also find it cool if you gave more importance to the minor characters by reviewing the sexual scenes as with the maids and having a relationship with them like dark sorceress, ladies talley and milese also the millaine or irinlia character of a side quest, a form that it could be as if the protagonist learned magic of enslavement and let them as the ryoko a slave with a certain freedom (I speak freedom like leaving them in the place just that devout to you) or simply to do something with which they fall in love with you, can be which I'm asking for a lot but I think it would look great for the relationship systems. 

sorry for the english errors i'm not native in the language

The problem is not a lack of motivation, ideas or possibilities, but simply time. My to-do list is very long so minor side characters will have to wait a long time before I get back to them and give them some more content. But I know that many of them are well beloved and people would like to see more of them. :)
