Actually, many characters were created, either the concept or specific parts of them, through a song
There's this character called Autumn (actually her provisional real name is korean: kim min-yeon I don't have much idea about korean names for now), and most of her character came over an animatic I imagined with this song

Actually, my oc is a kumiho thanks to this song, at first I was planning of making her a kitsune, but after hearing this song I did my research and found out that a kumiho suits better for the character, since their portrated as straight right evil and human eaters.
For the record kumihos are basically the korean variation of the myth around the kitsune, they both have nine tails and disguise as human to trick them, one of the difference is that kuminos are evil, while there are many stories of kitsunes being either bad, ambiguous and even good.
Also please excuse the name if it isn't correct or appropiate, I'm still researching about proper korean names, the same for her niece (kim ji-ji which I already know is a very weird name in korea for what I searched but it's provisional)
