They’re both standing underneath a tree that’s providing some shade to them

Koraidon: “Oh, Oh! Hi human! Nice to meet you, come here.”

Miraidon: “Koraidon, you really gotta invite every human you see?”

Koraidon: “Yes! I love humans and you do too, we’re best buds and practically the same Pokémon.”

Miraidon: “Sigh I hate that you’re right.”

They both seem incredibly inviting and sweet though.
