I'm seeing conflicting information regarding who made this. Running the image through SauceNAO gave me results for six different bad Pixiv IDs, all by Tami Tome Mo. Meanwhile, the Pinterest post I got this from, as well as a completely separate Pinterest post, claim that it was made by Oishiitigo. What's especially strange is that they both link to the same tweet, but said tweet does not contain the image at all. I genuinely have no idea what's going on here, so I'm just tagging with artist request for the time being.
