The original art belongs to merunyaa and only him.: https://ouo.io/5N2VW
and the edit of the completely naked kanna I found it here: https://ouo.io/UHMqVq
I don't know if IamzPlays is the one who created it or if he simply uploaded it. I really looked but I only found it from that page, the only thing I did is all the variations between the clothes.
