BUR #20903 has been approved by @nonamethanks.
create alias kirsten_(arknights) -> kristen_(arknights)
The character's name in the official english translation is "Kristen".
I have no idea where Kirsten came up, probably a mistranslation.
Character wiki
Since it would be correct to create an alias anyway, might as well make the official name the main tag.
Edit: I'm afraid I forgot to enter the "char:" before the new tag, I apologise for the confusion but it is the first time I have done such a BUR, next time I will be more careful.
I cannot edit it, I kindly ask an admin to do so (if possible).
