The Kanji for this artist's name can also be read as "Hinata" thus leading to this erroneous tag and artist wiki entry.
I already checked all the pics tagged with "hinata_kyousuke" to see if they linked back to Studio Himawari's site and they did, so I applied a tag script as I felt appropriate.
Here's some visual justification http://hugeup.com/v/534cbbf6
I can't, however, delete and merge/replace the "hinata_kyousuke" tag in the artist wiki at my current access level.
tl;dr: ITT Requesting mod/admin to step in and merge the hinata_kyousuke and himukai_kyousuke tags in the artist wiki.
