That's okay! the kids are from those yugiohs nobody cares about.

Ruka (gallitrap) is the teen girl. She's 14, stupidly well-connected, makes playing cards for a living, is friends with Eridan, of all trolls, and recently got one of her eyes ripped out of her face and so has a sweet eyepatch. She's usually pretty calm and thoughtful, but sucks at pop culture.

Yuma (soulbondee, being applied this round) is the teen boy. He's 13 and sucks at everything. He wants to be a CARD GAME CHAMPION, but he has really shitty tactics (he doesn't even know what the word means) and so loses a lot. Including the time he challenged a trash-collecting robot to a game and got his ass handed to him. He's exuberant and flamboyant, but no matter how many times he fails he will just KEEP BRINGING IT. Once he decides he's friends with someone, there is no getting out of it.
