Aliasing ガンマカオス → gammachaos
Link to alias
Reason:
Wandered across artist named ガンマカオス
at http://www.pixiv.net/member.php?id=315240
and uploaded post #913009
Saw two of the uploads had "Chaos" printed on them, which seemed like it could be an alternate name for artist. (but a tad on the semi-vague side ... considering all the artist names that start with Chaos.)
(There is an artist at e621 tagged as chaos_(artist), but I'm fairly sure it is a different artist.)
Thankfully I looked at an earlier upload and saw "GAMMACHAOS" was printed on it (at http://www.pixiv.net/member_illust.php?mode=medium&illust_id=1566015 )
EDIT: Checked gammachaos FA and has some of same art that is at ガンマカオス/gammachaos's pixiv gallery.
