mass update saburouta -> kokurikishi
create alias aihara_yuzuko -> aihara_yuzu
The artist now tagged as "saburouta" seems to be known as "kokurikishi" 虚空力士 from as far back as I can tell from the archive of their official site. Haven't found anything that hints towards that artist being or have once been known as "saburouta" other than the Pixiv URL "saburo-ta". サブロウタ is how the author of Citrus (a different person who does not seem to have an artist tag yet) is written and whom the entry should refer to.
Also, one of the main characters of Citrus is "Yuzu": 藍原 柚子（あいはら ゆず） Her name is not pronunced with a "ko".
