At the time, I had some kind of story in mind for these two. They never made it so far as to have names but they had personalities. The girl/woman there with the horns was this kids guide, his guardian. I think the idea was that she could only be seen him and other people that had their own guardians. Now in my defense, this was before I knew about Deathnote and such so no, I was not pulling my idea from there. It was more of a Faerie world kind of thing.
The young man pictured here, clasping his papers tight was supposed to be a bit melancholy and his counterpart was the opposite. She was realistic, however, about his chances of not making it ie. being killed by some monster or another sometime soon. She just had a good hold on making peace with whatever might happen before it actually happened or something like that. Something I find myself aspiring to quite a bit nowadays interestingly... Maybe I should revisit the idea.
Oh and she isn't really a she... or he. Just a being. No private bits to speak of and no need for that sort of thing for any of the guardians. There was a reason for that... but I can't remember anymore. I just knew that I didn't want any sort of sexualized relationship between the guardians and their wards, it was to be more... simple but also much more complex.
