In the Japanese version of the anime, whenever a Duelist declares the activation of a "Rank-Up-Magic" card, they do not say the phrase "I activate the Spell Card..." However, if the card is not a Normal Spell Card, they declare the card's property.
The Rank-Up-Magic cards were first introduced in the anime by Girag, who used "Rank-Up-Magic Barian's Force" to brainwash residents of Heartland in order to take the "Numbers" from Yuma, Astral and Shark. Each time it would be used to Rank-Up Xyz Monsters into "CXyz" monsters in order to overpower the "Numbers". Mizar used it next when he himself ranked up his "Number 107: Galaxy-Eyes Tachyon Dragon" in order to form its Chaos form. This monster wasn't fully revealed as the Sphere Field collapsed from its power. Alito and Girag both ranked up their respective "Number 10X" monsters. Both of them were defeated by Yuma and Astral (Girag was also defeated by Vector posing as Ray). In the same Duel where Girag was defeated, Yuma gained his own Rank-Up-Magic card in the form of "Limited Barian's Force" during his Duel with Girag from "Ray" but was later transformed into "Numeron Force" by ZEXAL II. Vector also demonstrated his mastery of Rank-Up-Magic cards when he used "Rank-Up-Magic Barian's Force" on his "Number 10X" monster, and also to brainwash Brooke Walker.
