It's most likely void princess rather than teletubbies because the artist has worked on elsword material and not teletubies.
Likely a confusion from the title because it sounds like the name for teletubbies in korean.
Changing the tag if no is going to argue otherwise.
I don't play Elsword and I am also not familiar with this character either and I was confused by the title itself and you so you are spot on my mistake here. I also checked this artist has drawn man oher Aisha drawings too so it was my mistake to not check twice before uploading so I am sorry about that. In short thanks for fixing the tags mates!
