Hau'oli City, the Battle Royal Dome.

Some of those researchers had even been sent by the Kalos League specifically to assist them.
The Goomy research project would benefit the Kalos League, too.
As the regional Pokémon League with the most Goomy,
if the team in Sinnoh could raise a Hisui Goodra and then selectively breed Hisui Goomy,
