@Rmii Where is this really form? Repeating the name of the copyright is *not* sufficient as the source, could you please let us know exactly the source for this?
Using SauceNAO, I was able to locate this image from a Pixiv with an artist entry at pixiv #69450845. It's really important to use reliable sources.
Please see these articles:
From artist request: Do not use this tag if there is a source available, such as the artist's homepage, blog, Pixiv, etc. Read howto:Artist, howto:Pixiv and create a new artist tag yourself, or ask for help in topic #8199: Artist tagging help.
