We do have plenty of demons so two humans is fine! For those who can make a human who already have a demon that would be perfect! If not that's alright! And partial amnesia is fine though they don't need to know about the real world as Gello's home is in its own realm. No one knows about what her home is like, not even the demons, so no worries! Things will be explained and detailed about her home!
