This card's name is based on a curtain raiser, a term used in acting to describe an opening performance for the main attraction of the show, where the first person on stage is often known for "raising the stage curtain".
This reflects both this card's Pendulum Effect and Monster Effect, as this monster acts as the player's "opening performance" by being the only monster they control, which allows it to gain 1100 ATK. Fittingly, in this card's debut in Yu-Gi-Oh! ARC-V episode 141141: "Swinging Back Into Action", this was the first monster Summoned by Sylvio Sawatari, which emphasizes the term in which this card is named after.
