Hailing from an invitation, Leon is curious what this Sigford could be. On the paper, it promised a relaxing gathering of champions. It's always good to see other region champions ~~with the possibility of challenging them!~~ so the Galar champion sets for the island. Flying over it on Charizard, his eyes are widened and his mouth opened slightly from the sight. It's huge! This Sigford must be very rich to own *This* Much land. He spots a ship coming into the docks of the beach and thought he should drop by there, in case that's where he should.

Nearing land, Charizard's strong wings kick up the sand and Leon jumps from his back. Even though the invitation seems fancy, Leon still wore his usual uniform: jersey, shorts, and his cape. Personally, a good look on him! He looks over to the ship closing in, seeing what he should do next. Maybe he has to be patient to be formally taken to the mansion? The champion decides to see what the others will do in this "Situation" Before going on.

But as Leon could see... There was a small ship approaching the island, as the sail from Unova finally arrived here carrying the dad of a certain rockstar gym leader and one Johto Champion. Chisana was hanging in the back of the ship, enjoying the waves and the silence. But then, when she got told they arrived, she leisurely got up, picking up her Pokeballs before a small staircase was extended for her, before she felt the fresh air.
"Whoever the hell owns this place, I am thankful for it. This is gonna be one hell of a vacation!" She said happily, finally letting all of her Pokémon out of their balls on the land. One powerhouse after another...

Amelia was already nearby, waiting under the shack. Seeing that the two champions are the first to arrive, she can't hold herself and start to approach the two while being accompanied by Machamps behind her (her bodyguards). She watches who must be Chisana (Jade) from Johto pulling up from her boat and then Leon from Galar land from his Charizard. "Welcome," She greets them with a smile. "I'm glad you two could make it~"

Leon is intrigued as this female approaches from down the boat. She's a small one and he's even more amazed if she's a champion! Seeing as how big this cruise ship, Leon wonders with a bit of nervousness if this is a place for him. Maybe this meetup is for the highly rich kind? It's not like the male wasn't in high standing too, but he never flaunt his money around, or use it to acquire anything so flashy. Once the female was within the sands, getting her shoes dirty (so she's not spoiled?) she summoned out her Pokémon. Leon's heart race seeing as the bulks appear. He could feel it now. This girl is a champion. The grin on his face widen and he almost made his way toward her when something from his peripheral vision catches him.

Yet another girl came into the fray. But what Leon really noticed was the two Machamp that follow her. Immediately, he assumes that even with the girl's small stature she could be holding a strong battling spirit that allowed her to have those Machamp by her side. It's not until she introduces to the both of them that the Galar champion understood she's the daughter who sent the invitations to everyone. Momentarily forgetting the female that came from the ship, Leon nods to- Amelia, was it?- in common courtesy before turning it into a small bow. At least he could offer that much to appear formal than he usually is. 

"It's great to be here!" He loudly says, standing back upright. "I'm Leon!" Even though the daughter might already know, it couldn't hurt for the other female from the cruise ship to get his name too, just in case. "This was an interesting proposal," He puts and finally decides to take in the view of the island at this standpoint.
