Rio -Rainbow Gate!-/Trivia
- Hey, It's That Voice!: Quite a few, actually:
- Rio Rollins is Yoko and Rei
- Mint Clark is Kirino, Mio and Azu-nyan
- Rosa Canyon is Lamia, Loveless and Hiyori Tamura (Doesn't help that Rosa herself from afar looked like a white-haired Lamia)
- Tom Howard is Garterbelt and Kimura-sensei. Better yet, he's Kotaro Taiga.
- Cartia is Erza and Yuuko.
- Linda is Mio and Ritsu
- Ania is Nia and Shizuka
- Villain of the Week Elvis is Ryu and Hisoka
- Dana is Yuki and Chouhi.
- Relationship Voice Actor: Since when did Yoko teach Nia how to play in a casino game?
- Also Rio and Linda are love rivals and pulled a 180 on their personalities.
- Shout-Out
- In episode 5, Howard tries to come up with some fancy name for some (no doubt lewd) event to commemorate the opening of the Sky Resort. One of these names is Dead or Alive Paradise, which may also double as a Mythology Gag, given that Rio ran the casino and was an unlockable character in the PSP game of the same name.
- Jack Mighty, a kid whose family specializes in disarming bombs, is a reference to Mighty Bomb Jack, another game by Tecmo. Jack's medallion even has a design on its face that resembles Bomb Jack's helmet.
- Perhaps the least subtle is where the program controlling the barriers around Linda is represented by a game of Star Force.
- Talking to Himself: The twins, who are voiced by Aya Uchida.
