Are they different individuals? I feel their style to be so close that I thought they' re same person at the beginning. Especially the Japan versus Korea episode, I remember Tomii has made at least 2 sets of similar match. And also the skin of models they used are quite alike.
@vaporeon天蝎宫 I will admit I don't know them personally. But what I do know is the quality of Kuron's work was significantly lower when he first began - which was way after Tomii - and I've watched it slowly but surely and naturally evolve over time. I could ramble about a bunch of theories I have, like I believe it's possible Kuron may be Korean, or maybe there's a reason "Kuron" sounds so similar to "clone", but it would be no more than a bunch of crackpot theories. However, what I do know for sure is that long after Tomii retired Kuron came out and said Tomii gave him permission to use his characters. And lately he has done so with Miyabi. Tomii also apparently is still around since he has recent bookmarks on pixiv. So, while it's hard to say for certain what's really going on, I do think it's safe to say they're 2 different people, but they communicate privately.
