There's an artist on Danbooru under uekan but that ID on Pixiv has been deleted. This artist goes by uekaaan? Probably the same person but the artist seems to want to be un-affiliated with the old account, hence the remake. Leaving it up to someone else to decide.

Please check the little '?' next to the artist if you are unsure.
Artist sources and aliases are listed there.
In this case uekan is the correct tag.
