I've beat the final boss, prince goap yesterday and then when there were 3 options afterward like: side with neala, with demon girl, or with myself. Then I've chose side with myself, which the two girls (neala and demon girl) became servants and then there's a threesome scene. And after that scenne it seems that I can't progress any further in the otherworld with the demon girl, even though her relationship status in the phone is just "shocked". I've also checked in the phone if there's any quest about her, but the texts are just "N" or "U", which I don't understand at all.
So, I would like to ask if that's all I can do with the demon girl with this ending, or is there any kind of hidden scenes about her that I've missed? Thanks.
