Aliasing aka_(pixiv193029) → aka_(pixiv).
Alasing/Mass editing aka_(artist) → aka_(red_shine).
Reason: aka_(artist) has a site to go by. aka_(pixiv193029) doesn't, and his/her username is complete gibberish, so we'll have to go by aka_(pixiv) it seems. I'm unsure about aliasing aka_(artist); given that the whole point of change is to disambiguate between two artists called aka, it probably makes sense to mass edit and leave the tag free (and potentially marked ambiguous).
