BUR #27729 has been approved by @nonamethanks.
category melusine_(genshin_impact) -> general
This is a species tag, nearly all the in-game Melusine have their own official names (i.e. Aeval, Sedene, Menthe, etc.) and are already tagged with such a majority of the time. There isn't a single representative of Melusine, they don't all look the same, they have distinct names and appearances, unlike something like a Pikachu or Renamon, which despite technically being species, function as characters.
