Tagging character for Fire Emblem Fuukasetsugetsu

I'm planning on mass uploading the official portrait art of Fire Emblem Fuukasetsugetsu and was wondering how to tag the characters without tags yet.

Should I go with full name: sylvain_jose_gautier
first name last name only: sylvain_gautier
or first name+(Fire Emblem Fuukasetsugetsu): sylvain_(fire_emblem)/sylvain_(fire_emblem_fuukasetsugetsu)

The current tags are all over the place:
dorothea (fire emblem)
edelgard von hresvelgr (fire emblem)
hubert von bestla

Currently there's a discussion going on regarding FE character tags in topic #16149 .
I believe it'd be best if you waited until a resolution is met, although you can go forward with uploading and setting character tags yourself.

I believe the common consensus is using the full name, if the full name is already taken you put _(fire_emblem) at the end of the character tag.
