BUR #21321 has been approved by @evazion.
create alias oneerissa_ravencroft -> malpha_ravencroft
create alias anerissa_ravencroft -> aradia_ravencroft
A user on Gelbooru requested these aliases, their Danbooru wikis both mention these names, and someone called Bob recently asked on the Discord if the tags should be changed. I don't know or care to know anything about vtubers but since I got no response when I asked on Discord myself, a BUR should sort it out.
