Archimedes the Pidove: The leader of the Pidove Post, he's very task-oriented and never dallies. He'll be fine to you as long as you're not getting in the way of delivering mail. He works alongside Pulse and Rhythm in ensuring that any lovey-dovey-mushy letters go where they ought to go. He owns several small posts in different villages so that mail can extend wherever it needs to.
Pulse the Luvdisc: she's a renowned matchmaker. She's usually right on the money about pairing Pokemon, but sometimes her poor hearing causes problems for her and she makes a faulty matchup. She lives in the Alomomola Bay out in the east.
Rhythm the Pelipper: a kind and gentle soul, he's very interested in helping Pokemon become happy. He offered to Pulse the opportunity to ride around in his mouth so she could unite couples all over the land; prior to that, she was stuck helping Pokemon couple up in the Alomomola Bay area only.
