I visited every international site to see what her name is across the different languages and here's what I got....

Arezu (English)
>Means "Desire" in Persian
Hinatsu (Japanese and German)
>Means "Summer Sun" in Japanese
Sera (Spanish)
>Means "Princess" in Hebrew
Marcia (French)
>Means "Dedicated to Mars" in Latin
Maru (Italian)
>Means "Round" in Japanese
Seonghwa (Korean)
>Means "Torch" in Korean
Huo xia (Chinese)
>Means "Summer Fire" in Chinese

It seems that she most likely will specialize in Fire-type Pokémon. Combine this info with her "lady Pokémon" (which is also referenced as female in every other language) and we potentially have ourselves a new Fire-type evolution or regional variant. Most of the other languages like Italian say she's taking care of "certain Queen Pokémon". I think any of the female only species are viable candidates but there's 2 Pokémon that come to mind and that is Vespiquen and Tsareena. Maybe they'll get new regional variants or maybe Combee and Steenee will get new Split Evolutions. What do you guys think?
