RaisingK, unless you can connect this picture or the account this picture came from to blueberry_(5959)'s original account, changing it back again is just vandalism.
According to his artist entry this is from his secondary Pixiv account. If that's not correct then fix the artist entry. I'm pretty sure RaisingK's edits are coming from an script he's running that uses artist entries to add artist tags to posts missing artist tags.
