Remember how she is greedy? Maybe it was all to buy that holy relic(slightly impossible since they are big treasures) or maybe she won one at the house of the protagonist that one night where everyone was drunk (more credible but still impossible). All I can say is that we don't know much about Yona other than being a super materialistic person. She can very well be a fallen noble or the princess of a fallen country who had a great debt and had to buy back the holy relic (family heirloom) hence the tendency to be materialistic. But I really don't know how she got it or who she really is. Hess are just my guesses. ┑( ̄Д  ̄)┍(〜 ̄△ ̄)〜
that's a very plausible theory..but the way she knows things is like..she has superpower..or like..in games the avatar that sells things and talk to u to explain shit..she feels like that..the know it all..but she like yuri too..thw know it all that is tired to be the only one who knows..hahahahaha..
I also had the theory she might be like a NPC (non playable character) ヾ(☆▽☆) but i also don't want to admit my other theories are wrong because this could be explained by the high level of education she might have received in the past. (づ ̄ ³ ̄)づ i have other hypothesis where Yona is like an error character made by the foolish deity that created all this messy situations Σ(  ̄□ ̄||)
But what she really is depends only on the author's genius mind so everything we said could be totally wrong ╮( ̄▽ ̄)╭

omg..there are so many interesting theories to choose from..huhu..one thing for sure..all these theories will not cease to make yona look goddamn awesome..she is so peculiar and interesting and crazy that i just cant take my eyes off her..fucking cracks me up everytime..this webtoon is cure to my heart..haha
i love how not only the character that isekai role is changing but also the sides!!typically only the isekai one change n become the main..but in here and the lady's butler..the sides character are getting the acknowledgement they deserve!fricking lovin this..
and seriously..yona is a baba yaga or some sort..how the hell die she get her hands on that?
