The bulk update request #1131 is active.

create alias shimizu_tsubasa (0) -> shizumi_tsubasa (86)

Reason: The artist changed their name some time back, essentially swapping the mi and zu syllables (originally 清水, shimizu, now replaced with シズミ, shizumi). The tweet mentioning the change is too far back for me to find, but their Twitter, Pixiv, and other sites have the new name.
