This is her Twitter account: https://twitter.com/sheep_Vtuber, and YouTube channel https://www.youtube.com/channel/UC0m3d4OsXqbx2m7ndrQj7Cw. I couldn't find her tag by searching the wiki and would be grateful if someone could point me to the correct tag.

Edit: Thank you @Damian0358! Added a few links to her wiki and tagged her other arts from her illustrator.
