Ereshkigal appears in the comedic OVA series Fate/Grand Carnival, adapted into lighthearted scenarios distinct from her main series portrayal. She engages in the streaming competition "Servantube," broadcasting content directly from her underworld domain. This activity places her in direct rivalry with fellow streamer Osakabehime as they compete for viewer popularity. Their competition escalates, culminating in Osakabehime employing extreme fanservice tactics that breach platform guidelines, resulting in her account's termination. Ereshkigal also administers the series' parody Olympics event, overseeing underworld-themed competitions. Her duties include supervising challenges like a lava race, reflecting her domain's aesthetics. This role connects to her mythological background as a ruler of the dead while integrating her into the OVA's absurdist events. Her depiction in this spin-off highlights comedic traits over dramatic ones, showcasing her competitive drive during streaming and her bureaucratic efficiency during the games. These elements recontextualize her underworld authority into humorous situations without altering her core identity.
