"RUMMY LABYRINTH" (ラミーラビリンス Ramīrabirinsu) is a duo of idols introduced in Cardfight!! Vanguard G: GIRS Crisis who later become a trio after teaming up with Saya Yatomi to join the U20 Championship in Cardfight!! Vanguard G: NEXT. They are also known as "RUMMY LABYRINTH with Saya" during this tournament.
In the G Quest's quest in Magallanica branch, they performed a concert and sang the song Don't Look Back.
It is later revealed that their idol activities are actually a ruse. Am and Luna are secretly pawns in Ryuzu Myoujin's ideal, valued for their powerful imaginations which allow them to manifest the Zodiac Time Beasts into reality using Depend Cards. Luna is initially unaware of this, however Am is aware and aids Ryuzu willingly because she knows that if the Stride Gate is opened, her comatose parents will be revived. After seeing Am in pain from the strain creating depend cards puts on the body, Luna decided to do it in her place. While summoning the Zodiac Time Beasts didn't put strain on Luna's body as it had for Am, Chrono, and Ryuzu, her mind shut down and she became a zombie who single-mindedly summons the Zodiac Time Beasts in order to save Am's parents.
