Artist.

Do not confuse this guy (his TW) as Ziv. He's not an impersonator, just someone who really like his art style and start using it.

The account of this is not the same as Ziv's. Especially with this now deleted Reddit post, it's pretty clear that the account is not Ziv, even though he try to confuses the people, for whatever reason.

Do note that just because the two has somewhat similar art style, doesn't mean it's the same person. On Discord, he often asks people in Ziv's server about his works, so he could studying Ziv's art style, seems that Ziv is his mentor before the sudden disappearance of him. Moreover, he draw Cookie rather than normal Touhou for whatever reason, again.
