Giraffe oversees the Revue auditions, controlling the Stage of Fate and seeking unpredictable performances from the Stage Girls. He maintains a calm demeanor, primarily observing the revues without direct intervention, though he manipulates circumstances to craft novel theatrical experiences. His signature verbal tic is the phrase "Wakarimasu" ("understood" or "I understand").

Across the franchise, Giraffe wields reality-warping abilities, granting wishes to victorious Stage Girls at the cost of the losers' motivation and brilliance. He orchestrated a time loop for Nana Daiba upon her request but later grew bored with its predictability. To break the loop, he manipulated events to ensure Hikari Kagura's arrival at Seisho Music Academy, triggering Karen Aijo's involvement in the auditions. In the mobile game *Revue Starlight Re LIVE*, his influence is indirect yet foundational; he created and distributed the "Elle Note," a notebook enabling its user (a young girl named Elle) to alter reality through storytelling, indirectly instigating the game's events.

In the second anime film, Giraffe orchestrates the "wi(l)d-screen baroque" revue to help the Seisho Stage Girls resolve lingering personal conflicts. He ultimately performs a heroic sacrifice, distributing fragments of his power to each girl as "fuel" for their brilliance and setting his body ablaze to create an unprecedented stage for Karen and Hikari's reunion. This act catalyzes their commitment to advancing their acting careers.

In the spin-off *Shōjo☆Conte All Starlight*, Giraffe adopts a more comedic role. He appears alongside Elle to initiate auditions but faces reluctance and interruptions from the Stage Girls. His attempts at awkward small talk with Elle highlight his comically serious demeanor, contrasting with his typically enigmatic presence. He oversees the chaotic audition battles between Seisho and rival schools like Siegfeld Institute, Rinmeikan Girls School, and Frontier School of Arts.
