kano, lefthand are the same artist
For some reason pictures sourced from http://kano12456.web.fc2.com/index.html give kano as the artist name, but from what I can tell the pixiv account http://www.pixiv.net/member.php?id=15975 is the same artist. Everything linked from the pixiv seems to be tagged with lefthand.
There's only three kano tagged pics so changing them manually wouldn't be a problem. The issue is changing what the uploader suggests his name is. I'm not sure how to go about doing that, to be honest. Does it just involve merging the wiki entries into either of the two names? Thanks.
