Yeah I thought that the episode was good as well. The predictability of how Shark would win didn't bother me as much because of the awesome looking manga monsters. Hopefully Rio's dueling and deck isn't too similar to Shark's so we'd finally have a duel with duelists using only cards we've never seen before.
They were fun, cool and fitting. Something you'd expect from a brother and sister relationship. Yeah I'd like an explanation about the rings as well. Rio hasn't really come off as cool to me with the little that was shown of her, but I'm thinking that will change in the next episode.
She's dueling somebody with a Number card? That's wonderful news! Maybe she'll keep the card for herself and use it to help defeat other Number card holders. She'll most likely give it to Astral, though. Speaking of Astral, with her involvement with the Barian I'm thinking that she'll be able to see him. Without a Number card herself, she'll probably use the strategy Shark used in episode 10 against Yuma to get rid of Hope, so I'm looking forward to seeing how she'll pull it off. I still thought that Aki and Sherry were handled decently despite becoming blander every passing episode. Rio will probably shine in the next 20 to 30 episodes or so, having her personality and story fleshed out and then be done with like most female characters. Her Ice deck would also probably be on sale at that time.
Has anyone's eyes caught this title?:
"Kotori Chaos Xyz Changes!? The Tumultuous Sports Duel Tournament"
Oh wow. Kotori possibly dueling and/or becoming evil to trick Yuma sounds very interesting. Maybe it will increase her likability. The upcoming episodes with Alik and Misael sound very interesting as well. Galaxy Eyes master? I wonder what sort of development Kaito could get from that.
