Yabuki Kentarou and Yamaiwa Shuuhai came from when the uploader copy-pasted the tags from post #2575186. I don't know where hju came from: even if they're a reposter, this image isn't even on their Pixiv.
For now, I've gone ahead and created an artist entry for the artist who's Pixiv and Twitter this image appears on, and removed the other tags. If this is actually a trace or recolor or repost, please readd accordingly
