I guess this review came as no surprise to anyone who's been watching the Fantasy Zone. Time now for Rio Rainbow Gate.

Rio Rainbow Gate is an anime created off the back of Tecmo Koei's line of Pachinko games. Rio herself also appeared in Dead or Alive Xtreme which also sums up the shows content.
The story is about a Casino Dealer named Rio Rollins who is the daughter of a more famous Casino Dealer. She works at Howard Resort who is owned by a perverted yet strangely good and honest boss. Her mission is to get the mystical Gate Cards which will grant her a wish and hopefully get her closer to her missing mother who isn't really missing. Along the way she must take down her step sister who is also her greatest rival.
Oh boy Formulaic or what, it sounds like YuGiOh zero with boobs and that's exactly what it is and it comes with an impressive checklist of cliches.
1. Annoying child character who becomes an episode plot point and ends up as a surrogate younger sister.
2. Main character is loved by everyone and is ridiculously talented at what she does and knows Heart of the Cards Magic.
3. Early bad guys talk big but still lose.
4. Side characters do nothing but look pretty, one of them will be emotionless.
5. Clumsy character is ridiculously adorable and over exaggerated.
6. There is a line of sexy cosplay to look forward to.
7. Rival shows up unexpected but acts as a friend.
8. There's a robot girl with a gimmick of losing her head.
9. Casino Games are a bit over the top and always serious business.
10. Big enemy shows up and derails main character using psychological torture.
11. Rival reveals that she's behind all this and challenges main character.
12. Rival is stronger than main character and crushes her spirit in the process.
13. Early bad guys switch sides out of respect for their former enemy.
14. Main character goes on a self discovery journey and reclaims her lost spirit and confidence through an unknown spirit guardian who is really someone close to her.
15. Main Character challenges rival again and wins.
16. Big enemy gets desperate and tries to do an ass pull moment.
17. Main character pulls a Madoka Magica God Scene.
18. Series ends with sudden new characters indicating a second season that won't happen.
I don't normally write with this much sarcasm in my language but it kind of warrants it. Rio Rainbow Gate proves how bad Yu-Gi-Oh's storyline was by re-writing it as a proper anime show, adding boobs and even more lousy cliches.
At the very least the show is reasonably entertaining, you can easily find yourself absorbed in the weirdness around you particularly Anya Helsing when she manages to destroy three supercars through bending trees by accident through her sheer clumsiness. But still it's budget anime at it's finest and you certainly won't gain anything watching it. No dub thank god, it's bad enough in Japanese.
Final Verdict: It's terrible but good terrible, for the price you pay for it, it certainly is worth the money and worth at least one viewing and I will admit that I want to go to a Casino now, so at the very least it's achieved it's primary goal.
