"Remielle" comes from an early translation of leaked Chinese beta server content. These translations are usually either "close enough" or the spelling is changed for the English localisation. The initial tag was created (although improperly, it was missing an underscore before the qualifier) by @Lina101 who also fills in some other missing miHoYo copyright tags but doesn't make wikis for them, so this ping is a reminder to please do it properly in the future.
As above, there is a BUR to adjust the spelling to the live server name.
