Fittingly, "Gagaga Girl" was the monster used with this card's effect in each of its appearances in the Yu-Gi-Oh! ZEXAL anime.
This card's OCG/TCG effect to change the Special Summoned "Gagaga" monster's Level to 4 is an alteration of its anime effect, which allows the player to increase the Special Summoned monster's Level by 1. In the anime, this card was used to Special Summon the Level 3 "Gagaga Girl" and increase its Level by 1, thus making it a Level 4 monster.
