I think Lock, Shock, and Barrel could be an interesting choice for best man, in a sort of comical way. They could be trying their best to be proper and helpful during the wedding preparations, but of course, they'd get into some minor mischief along the way.

Harry would be an obvious choice for the best man. He's Ron's best friend, they've been through so much together. As for the maid of honor, it could be Ginny. Ginny and Hermione are good friends, and Ginny is also Ron's sister, so it would be a very fitting choice.

For the maid of honor, I think it would be Lusamine. As Lillie's mother, she would be the perfect person to support Lillie on her big day and ensure everything goes smoothly.
Lisbeth would make a great maid of honor. She's been a good friend to Asuna and has been through a lot with both of them. As for the best man, Klein could be a good choice. He's Kirito's long - time friend and has always been there for him in the game world.

In some fanfictions, Nico could be the best man for Percy. Their relationship has evolved over time, and Nico has proven himself to be a loyal friend. For Annabeth, Thalia could be the maid of honor.
